# --description--
|
||||
|
||||
Instead of adjusting your overall background or the color of the text to make the foreground easily readable, you can add a `background-color` to the element holding the text you want to emphasize. This challenge uses `rgba()` instead of `hex` codes or normal `rgb()`.
|
||||
|
||||
<blockquote>rgba stands for:<br> r = red<br> g = green<br> b = blue<br> a = alpha/level of opacity</blockquote>
|
||||
|
||||
The RGB values can range from 0 to 255. The alpha value can range from 1, which is fully opaque or a solid color, to 0, which is fully transparent or clear. `rgba()` is great to use in this case, as it allows you to adjust the opacity. This means you don't have to completely block out the background.
|
||||
|
||||
You'll use `background-color: rgba(45, 45, 45, 0.1)` for this challenge. It produces a dark gray color that is nearly transparent given the low opacity value of 0.1.
|
||||
|
||||
# --instructions--
|
||||
|
||||
To make the text stand out more, adjust the `background-color` of the `h4` element to the given `rgba()` value.
|
||||
|
||||
Also for the `h4`, remove the `height` property and add `padding` of 10px.
|
||||
|
||||
# --hints--
|
||||
|
||||
Your code should add a `background-color` property to the `h4` element set to `rgba(45, 45, 45, 0.1)`.
|
||||
|
||||
```js
|
||||
assert(
|
||||
/(background-color|background):rgba\(45,45,45,0?\.1\)(;?}|;)/gi.test(
|
||||
code.replace(/\s/g, '')
|
||||
)
|
||||
);
|
||||
```
|
||||
|
||||
Your code should add a `padding` property to the `h4` element and set it to 10 pixels.
|
||||
|
||||
```js
|
||||
assert(
|
||||
$('h4').css('padding-top') == '10px' &&
|
||||
$('h4').css('padding-right') == '10px' &&
|
||||
$('h4').css('padding-bottom') == '10px' &&
|
||||
$('h4').css('padding-left') == '10px'
|
||||
);
|
||||
```
|
||||
|
||||
The `height` property on the `h4` element should be removed.
|
||||
|
||||
```js
|
||||
assert(!($('h4').css('height') == '25px'));
|
||||
```

title: Adjust the Color of Various Elements to Complementary Colors
|

# --description--
|
||||
|
||||
The Complementary Colors challenge showed that opposite colors on the color wheel can make each other appear more vibrant when placed side-by-side. However, the strong visual contrast can be jarring if it's overused on a website, and can sometimes make text harder to read if it's placed on a complementary-colored background. In practice, one of the colors is usually dominant and the complement is used to bring visual attention to certain content on the page.
|
||||
|
||||
# --instructions--
|
||||
|
||||
This page will use a shade of teal (`#09A7A1`) as the dominant color, and its orange (`#FF790E`) complement to visually highlight the sign-up buttons. Change the `background-color` of both the `header` and `footer` from black to the teal color. Then change the `h2` text `color` to teal as well. Finally, change the `background-color` of the `button` to the orange color.
|
||||
|
||||
# --hints--
|
||||
|
||||
The `header` element should have a `background-color` of #09A7A1.
|
||||
|
||||
```js
|
||||
assert($('header').css('background-color') == 'rgb(9, 167, 161)');
|
||||
```
|
||||
|
||||
The `footer` element should have a `background-color` of #09A7A1.
|
||||
|
||||
```js
|
||||
assert($('footer').css('background-color') == 'rgb(9, 167, 161)');
|
||||
```
|
||||
|
||||
The `h2` element should have a `color` of #09A7A1.
|
||||
|
||||
```js
|
||||
assert($('h2').css('color') == 'rgb(9, 167, 161)');
|
||||
```
|
||||
|
||||
The `button` element should have a `background-color` of #FF790E.
|
||||
|
||||
```js
|
||||
assert($('button').css('background-color') == 'rgb(255, 121, 14)');
|
||||
```

|

You can specify the height of an element using the `height` property in CSS, similar to the `width` property. Here's an example that changes the height of an image to 20px:
|
||||
|
||||
```css
|
||||
img {
|
||||
height: 20px;
|
||||
}
|
||||
```
|
||||
|
||||
# --instructions--
|
||||
|
||||
Add a `height` property to the `h4` tag and set it to 25px.
|
||||
|
||||
**Note:** You may need to be at 100% zoom to pass the test on this challenge.
|
||||
|
||||
# --hints--
|
||||
|
||||
Your code should change the `h4` `height` property to a value of 25 pixels.
|
||||
|
||||
```js
|
||||
assert(
|
||||
Math.round(document.querySelector('h4').getBoundingClientRect().height) ===
|
||||
25 &&
|
||||
/h4{\S*height:25px(;\S*}|})/.test($('style').text().replace(/\s/g, ''))
|
||||
);

title: Adjust the Hover State of an Anchor Tag

# --description--
|
||||
|
||||
This challenge will touch on the usage of pseudo-classes. A pseudo-class is a keyword that can be added to selectors, in order to select a specific state of the element.
|
||||
|
||||
For example, the styling of an anchor tag can be changed for its hover state using the `:hover` pseudo-class selector. Here's the CSS to change the `color` of the anchor tag to red during its hover state:
|
||||
|
||||
```css
|
||||
a:hover {
|
||||
color: red;
|
||||
}
|
||||
```
|
||||
|
||||
# --instructions--
|
||||
|
||||
The code editor has a CSS rule to style all `a` tags black. Add a rule so that when the user hovers over the `a` tag, the `color` is blue.
|
||||
|
||||
# --hints--
|
||||
|
||||
The anchor tag `color` should remain black, only add CSS rules for the `:hover` state.
|
||||
|
||||
```js
|
||||
assert($('a').css('color') == 'rgb(0, 0, 0)');
|
||||
```
|
||||
|
||||
The anchor tag should have a `color` of blue on hover.
|
||||
|
||||
```js
|
||||
assert(
|
||||
code.match(
|
||||
/a:hover\s*?{\s*?color:\s*?(blue|rgba\(\s*?0\s*?,\s*?0\s*?,\s*?255\s*?,\s*?1\s*?\)|#00F|rgb\(\s*?0\s*?,\s*?0\s*?,\s*?255\s*?\))\s*?;\s*?}/gi

Colors have several characteristics including hue, saturation, and lightness. CSS3 introduced the `hsl()` property as an alternative way to pick a color by directly stating these characteristics.
|
||||
|
||||
**Hue** is what people generally think of as 'color'. If you picture a spectrum of colors starting with red on the left, moving through green in the middle, and blue on right, the hue is where a color fits along this line. In `hsl()`, hue uses a color wheel concept instead of the spectrum, where the angle of the color on the circle is given as a value between 0 and 360.

**Saturation** is the amount of gray in a color. A fully saturated color has no gray in it, and a minimally saturated color is almost completely gray. This is given as a percentage with 100% being fully saturated.
|
||||
|
||||
**Lightness** is the amount of white or black in a color. A percentage is given ranging from 0% (black) to 100% (white), where 50% is the normal color.
|
||||
|
||||
Here are a few examples of using `hsl()` with fully-saturated, normal lightness colors:
|
||||
|
||||
<table class='table table-striped'><thead><tr><th>Color</th><th>HSL</th></tr></thead><tbody><tr><td>red</td><td>hsl(0, 100%, 50%)</td></tr><tr><td>yellow</td><td>hsl(60, 100%, 50%)</td></tr><tr><td>green</td><td>hsl(120, 100%, 50%)</td></tr><tr><td>cyan</td><td>hsl(180, 100%, 50%)</td></tr><tr><td>blue</td><td>hsl(240, 100%, 50%)</td></tr><tr><td>magenta</td><td>hsl(300, 100%, 50%)</td></tr></tbody></table>
|
||||
|
||||
# --instructions--
|
||||
|
||||
Change the `background-color` of each `div` element based on the class names (`green`, `cyan`, or `blue`) using `hsl()`. All three should have full saturation and normal lightness.
|
||||
|
||||
# --hints--
|
||||
|
||||
Your code should use the `hsl()` property to declare the color `green`.
|
||||
|
||||
```js
|
||||
assert(code.match(/\.green\s*?{\s*?background-color\s*:\s*?hsl/gi));
|
||||
```
|
||||
|
||||
Your code should use the `hsl()` property to declare the color `cyan`.
|
||||
|
||||
```js
|
||||
assert(code.match(/\.cyan\s*?{\s*?background-color\s*:\s*?hsl/gi));
|
||||
```
|
||||
|
||||
Your code should use the `hsl()` property to declare the color `blue`.
|
||||
|
||||
```js
|
||||
assert(code.match(/\.blue\s*?{\s*?background-color\s*:\s*?hsl/gi));
|
||||
```
|
||||
|
||||
The `div` element with class `green` should have a `background-color` of green.
|
||||
|
||||
```js
|
||||
assert($('.green').css('background-color') == 'rgb(0, 255, 0)');
|
||||
```
|
||||
|
||||
The `div` element with class `cyan` should have a `background-color` of cyan.
|
||||
|
||||
```js
|
||||
assert($('.cyan').css('background-color') == 'rgb(0, 255, 255)');
|
||||
```
|
||||
|
||||
The `div` element with class `blue` should have a `background-color` of blue.
|
||||
|
||||
```js
|
||||
assert($('.blue').css('background-color') == 'rgb(0, 0, 255)');
|
||||
```

|
||||
|
||||
The font size of header tags (`h1` through `h6`) should generally be larger than the font size of paragraph tags. This makes it easier for the user to visually understand the layout and level of importance of everything on the page. You use the `font-size` property to adjust the size of the text in an element.
|
||||
|
||||
# --instructions--
|
||||
|
||||
To make the heading significantly larger than the paragraph, change the `font-size` of the `h4` tag to 27 pixels.
|
||||
|
||||
# --hints--
|
||||
|
||||
Your code should add a `font-size` property to the `h4` element set to 27 pixels.
|
||||
|
||||
```js
|
||||
assert($('h4').css('font-size') == '27px');

# --description--
|
||||
|
||||
The `hsl()` option in CSS also makes it easy to adjust the tone of a color. Mixing white with a pure hue creates a tint of that color, and adding black will make a shade. Alternatively, a tone is produced by adding gray or by both tinting and shading. Recall that the 's' and 'l' of `hsl()` stand for saturation and lightness, respectively. The saturation percent changes the amount of gray and the lightness percent determines how much white or black is in the color. This is useful when you have a base hue you like, but need different variations of it.
|
||||
|
||||
# --instructions--
|
||||
|
||||
All elements have a default `background-color` of `transparent`. Our `nav` element currently appears to have a `cyan` background, because the element behind it has a `background-color` set to `cyan`. Add a `background-color` to the `nav` element so it uses the same `cyan` hue, but has `80%` saturation and `25%` lightness values to change its tone and shade.
|
||||
|
||||
# --hints--
|
||||
|
||||
The `nav` element should have a `background-color` of the adjusted cyan tone using the `hsl()` property.
|
||||
|
||||
```js
|
||||
assert(
|
||||
code.match(/nav\s*?{\s*?background-color:\s*?hsl\(180,\s*?80%,\s*?25%\)/gi)
|

You can specify the width of an element using the `width` property in CSS. Values can be given in relative length units (such as `em`), absolute length units (such as `px`), or as a percentage of its containing parent element. Here's an example that changes the width of an image to 220px:
|
||||
|
||||
```css
|
||||
img {
|
||||
width: 220px;
|
||||
}
|
||||
```
|
||||
|
||||
# --instructions--
|
||||
|
||||
Add a `width` property to the entire card and set it to an absolute value of 245px. Use the `fullCard` class to select the element.
|
||||
|
||||
# --hints--
|
||||
|
||||
Your code should change the `width` property of the card to 245 pixels by using the `fullCard` class selector.
|
||||
|
||||
```js
|
||||
const fullCard = code.match(/\.fullCard\s*{[\s\S]+?[^}]}/g);
|
||||
assert(
|
||||
fullCard &&
|
||||
/width\s*:\s*245px\s*(;|})/gi.test(fullCard[0]) &&
|
||||
$('.fullCard').css('maxWidth') === 'none'

);

|
||||
|
||||
There are a variety of ways to alter the animation rates of similarly animated elements. So far, this has been achieved by applying an `animation-iteration-count` property and setting `@keyframes` rules.
|
||||
|
||||
To illustrate, the animation on the right consists of two stars that each decrease in size and opacity at the 20% mark in the `@keyframes` rule, which creates the twinkle animation. You can change the `@keyframes` rule for one of the elements so the stars twinkle at different rates.
|
||||
|
||||
# --instructions--
|
||||
|
||||
Alter the animation rate for the element with the class name of `star-1` by changing its `@keyframes` rule to 50%.
|
||||
|
||||
# --hints--
|
||||
|
||||
The `@keyframes` rule for the `star-1` class should be 50%.
|
||||
|
||||
```js
|
||||
assert(code.match(/twinkle-1\s*?{\s*?50%/g));
|
||||
```

# --description--
|
||||
|
||||
The previous challenges covered how to use some of the animation properties and the `@keyframes` rule. Another animation property is the `animation-iteration-count`, which allows you to control how many times you would like to loop through the animation. Here's an example:
|
||||
|
||||
```css
|
||||
animation-iteration-count: 3;
|
||||
```
|
||||
|
||||
In this case the animation will stop after running 3 times, but it's possible to make the animation run continuously by setting that value to `infinite`.
|
||||
|
||||
# --instructions--
|
||||
|
||||
To keep the ball bouncing on the right on a continuous loop, change the `animation-iteration-count` property to `infinite`.
|
||||
|
||||
# --hints--
|
||||
|
||||
The `animation-iteration-count` property should have a value of `infinite`.
|
||||
|
||||
```js
|
||||
assert($('#ball').css('animation-iteration-count') == 'infinite');
|
||||
```

title: Animate Multiple Elements at Variable Rates

# --description--
|
||||
|
||||
In the previous challenge, you changed the animation rates for two similarly animated elements by altering their `@keyframes` rules. You can achieve the same goal by manipulating the `animation-duration` of multiple elements.
|
||||
|
||||
In the animation running in the code editor, there are three stars in the sky that twinkle at the same rate on a continuous loop. To make them twinkle at different rates, you can set the `animation-duration` property to different values for each element.
|
||||
|
||||
# --instructions--
|
||||
|
||||
Set the `animation-duration` of the elements with the classes `star-1`, `star-2`, and `star-3` to 1s, 0.9s, and 1.1s, respectively.
|
||||
|
||||
# --hints--
|
||||
|
||||
The `animation-duration` property for the star with class `star-1` should remain at 1s.
|
||||
|
||||
```js
|
||||
assert($('.star-1').css('animation-duration') == '1s');
|
||||
```
|
||||
|
||||
The `animation-duration` property for the star with class `star-2` should be 0.9s.
|
||||
|
||||
```js
|
||||
assert($('.star-2').css('animation-duration') == '0.9s');
|
||||
```
|
||||
|
||||
The `animation-duration` property for the star with class `star-3` should be 1.1s.
|
||||
|
||||
```js
|
||||
assert($('.star-3').css('animation-duration') == '1.1s');
|
||||

|

|
||||
Another positioning technique is to center a block element horizontally. One way to do this is to set its `margin` to a value of auto.
|
||||
|
||||
This method works for images, too. Images are inline elements by default, but can be changed to block elements when you set the `display` property to `block`.
|
||||
|
||||
# --instructions--
|
||||
|
||||
Center the `div` on the page by adding a `margin` property with a value of `auto`.
|
||||
|
||||
# --hints--
|
||||
|
||||
The `div` should have a `margin` set to `auto`.
|
||||
|
||||
```js
|
||||
assert(code.match(/margin:\s*?auto;/g));

||||

# --description--
|
||||
|
||||
CSS treats each HTML element as its own box, which is usually referred to as the <dfn>CSS Box Model</dfn>. Block-level items automatically start on a new line (think headings, paragraphs, and divs) while inline items sit within surrounding content (like images or spans). The default layout of elements in this way is called the <dfn>normal flow</dfn> of a document, but CSS offers the position property to override it.
|
||||
|
||||
When the position of an element is set to `relative`, it allows you to specify how CSS should move it *relative* to its current position in the normal flow of the page. It pairs with the CSS offset properties of `left` or `right`, and `top` or `bottom`. These say how many pixels, percentages, or ems to move the item *away* from where it is normally positioned. The following example moves the paragraph 10 pixels away from the bottom:
|
||||
|
||||
```css
|
||||
p {
|
||||
position: relative;
|
||||
bottom: 10px;
|
||||
}
|
||||
```
|
||||
|
||||
Changing an element's position to relative does not remove it from the normal flow - other elements around it still behave as if that item were in its default position.
|
||||
|
||||
**Note:** Positioning gives you a lot of flexibility and power over the visual layout of a page. It's good to remember that no matter the position of elements, the underlying HTML markup should be organized and make sense when read from top to bottom. This is how users with visual impairments (who rely on assistive devices like screen readers) access your content.
|
||||
|
||||
# --instructions--
|
||||
|
||||
Change the `position` of the `h2` to `relative`, and use a CSS offset to move it 15 pixels away from the `top` of where it sits in the normal flow. Notice there is no impact on the positions of the surrounding h1 and p elements.
|
||||
|
||||
# --hints--
|
||||
|
||||
The `h2` element should have a `position` property set to `relative`.
|
||||
|
||||
```js
|
||||
assert($('h2').css('position') == 'relative');
|
||||
```
|
||||
|
||||
Your code should use a CSS offset to relatively position the `h2` 15px away from the `top` of where it normally sits.
|
||||
|
||||
```js
|
||||
assert($('h2').css('top') == '15px');

title: Change Animation Timing with Keywords

# --description--
|
||||
|
||||
In CSS animations, the `animation-timing-function` property controls how quickly an animated element changes over the duration of the animation. If the animation is a car moving from point A to point B in a given time (your `animation-duration`), the `animation-timing-function` says how the car accelerates and decelerates over the course of the drive.
|
||||
|
||||
There are a number of predefined keywords available for popular options. For example, the default value is `ease`, which starts slow, speeds up in the middle, and then slows down again in the end. Other options include `ease-out`, which is quick in the beginning then slows down, `ease-in`, which is slow in the beginning, then speeds up at the end, or `linear`, which applies a constant animation speed throughout.
|
||||
|
||||
# --instructions--
|
||||
|
||||
For the elements with id of `ball1` and `ball2`, add an `animation-timing-function` property to each, and set `#ball1` to `linear`, and `#ball2` to `ease-out`. Notice the difference between how the elements move during the animation but end together, since they share the same `animation-duration` of 2 seconds.
|
||||
|
||||
# --hints--
|
||||
|
||||
The value of the `animation-timing-function` property for the element with the id `ball1` should be `linear`.
|
||||
|
||||
```js
|
||||
const ball1Animation = __helpers.removeWhiteSpace(
|
||||
$('#ball1').css('animation-timing-function')
|
||||
);
|
||||
assert(ball1Animation == 'linear' || ball1Animation == 'cubic-bezier(0,0,1,1)');
|
||||
```
|
||||
|
||||
The value of the `animation-timing-function` property for the element with the id `ball2` should be `ease-out`.
|
||||
|
||||
```js
|
||||
const ball2Animation = __helpers.removeWhiteSpace(

title: Change the Position of Overlapping Elements with the z-index Property

# --description--
|
||||
|
||||
When elements are positioned to overlap (i.e. using `position: absolute | relative | fixed | sticky`), the element coming later in the HTML markup will, by default, appear on the top of the other elements. However, the `z-index` property can specify the order of how elements are stacked on top of one another. It must be an integer (i.e. a whole number and not a decimal), and higher values for the `z-index` property of an element move it higher in the stack than those with lower values.
|
||||
|
||||
# --instructions--
|
||||
|
||||
Add a `z-index` property to the element with the class name of `first` (the red rectangle) and set it to a value of 2 so it covers the other element (blue rectangle).
|
||||
|
||||
# --hints--
|
||||
|
||||
The element with class `first` should have a `z-index` value of 2.
|
||||
|
||||
```js
|
||||
assert($('.first').css('z-index') == '2');
|
||||
```

title: Create a Gradual CSS Linear Gradient
|
||||

# --description--
|
||||
|
||||
Applying a color on HTML elements is not limited to one flat hue. CSS provides the ability to use color transitions, otherwise known as gradients, on elements. This is accessed through the `background` property's `linear-gradient()` function. Here is the general syntax:
|
||||
|
||||
```css
|
||||
background: linear-gradient(gradient_direction, color 1, color 2, color 3, ...);
|
||||
```
|
||||
|
||||
The first argument specifies the direction from which color transition starts - it can be stated as a degree, where `90deg` makes a horizontal gradient (from left to right) and `45deg` makes a diagonal gradient (from bottom left to top right). The following arguments specify the order of colors used in the gradient.
|
||||
|
||||
Example:
|
||||
|
||||
```css
|
||||
background: linear-gradient(90deg, red, yellow, rgb(204, 204, 255));
|
||||
```
|
||||
|
||||
# --instructions--
|
||||
|
||||
Use a `linear-gradient()` for the `div` element's `background`, and set it from a direction of 35 degrees to change the color from `#CCFFFF` to `#FFCCCC`.
|
||||
|
||||
# --hints--
|
||||
|
||||
The `div` element should have a `linear-gradient` `background` with the specified direction and colors.
|
||||
|
||||
```js
|
||||
assert(
|
||||
$('div')
|
||||
.css('background-image')
|
||||
.match(
|
||||
/linear-gradient\(35deg, rgb\(204, 255, 255\), rgb\(255, 204, 204\)\)/gi
|
||||
)

||||
);

By manipulating different selectors and properties, you can make interesting shapes. One of the easier ones to try is a crescent moon shape. For this challenge you need to work with the `box-shadow` property that sets the shadow of an element, along with the `border-radius` property that controls the roundness of the element's corners.
|
||||
|
||||
You will create a round, transparent object with a crisp shadow that is slightly offset to the side - the shadow is actually going to be the moon shape you see.
|
||||
|
||||
In order to create a round object, the `border-radius` property should be set to a value of 50%.
|
||||
|
||||
You may recall from an earlier challenge that the `box-shadow` property takes values for `offset-x`, `offset-y`, `blur-radius`, `spread-radius` and a color value in that order. The `blur-radius` and `spread-radius` values are optional.
|
||||
|
||||
# --instructions--
|
||||
|
||||
Manipulate the square element in the editor to create the moon shape. First, change the `background-color` to `transparent`, then set the `border-radius` property to 50% to make the circular shape. Finally, change the `box-shadow` property to set the `offset-x` to 25px, the `offset-y` to 10px, `blur-radius` to 0, `spread-radius` to 0, and color to `blue`.
|
||||
|
||||
# --hints--
|
||||
|
||||
The value of the `background-color` property should be set to `transparent`.
|
||||
|
||||
```js
|
||||
assert(code.match(/background-color:\s*?transparent;/gi));
|
||||
```
|
||||
|
||||
The value of the `border-radius` property should be set to `50%`.
|
||||
|
||||
```js
|
||||
assert(code.match(/border-radius:\s*?50%;/gi));
|
||||
```
|
||||
|
||||
The value of the `box-shadow` property should be set to 25px for `offset-x`, 10px for `offset-y`, 0 for `blur-radius`, 0 for `spread-radius`, and finally `blue` for the color.
|
||||
|
||||
```js
|
||||
assert(
|
||||
code.match(/box-shadow:\s*?25px\s+?10px\s+?0(px)?\s+?0(px)?\s+?blue\s*?;/gi)
|
||||
);

You can use the `hr` tag to add a horizontal line across the width of its containing element. This can be used to define a change in topic or to visually separate groups of content.
|
||||
|
||||
# --instructions--
|
||||
|
||||
Add an `hr` tag underneath the `h4` which contains the card title.
|
||||
|
||||
**Note:** In HTML, `hr` is a self-closing tag, and therefore doesn't need a separate closing tag.
|
||||
|
||||
# --hints--
|
||||
|
||||
Your code should add an `hr` tag to the markup.
|
||||
|
||||
```js
|
||||
assert($('hr').length == 1);
|
||||
```
|
||||
|
||||
The `hr` tag should come between the title and the paragraph.
|
||||
|
||||
```js
|
||||
assert(code.match(/<\/h4>\s*?<hr(>|\s*?\/>)\s*?<p>/gi));

title: Create a More Complex Shape Using CSS and HTML

# --description--
|
||||
|
||||
One of the most popular shapes in the world is the heart shape, and in this challenge you'll create one using pure CSS. But first, you need to understand the `::before` and `::after` pseudo-elements. These pseudo-elements are used to add something before or after a selected element. In the following example, a `::before` pseudo-element is used to add a rectangle to an element with the class `heart`:
|
||||
|
||||
```css
|
||||
.heart::before {
|
||||
content: "";
|
||||
background-color: yellow;
|
||||
border-radius: 25%;
|
||||
position: absolute;
|
||||
height: 50px;
|
||||
width: 70px;
|
||||
top: -50px;
|
||||
left: 5px;
|
||||
}
|
||||
```
|
||||
|
||||
For the `::before` and `::after` pseudo-elements to function properly, they must have a defined `content` property. This property is usually used to add things like a photo or text to the selected element. When the `::before` and `::after` pseudo-elements are used to make shapes, the `content` property is still required, but it's set to an empty string. In the above example, the element with the class of `heart` has a `::before` pseudo-element that produces a yellow rectangle with height and width of `50px` and `70px`, respectively. This rectangle has round corners due to its 25% `border-radius` and is positioned absolutely at `5px` from the left and `50px` above the top of the element.
|
||||
|
||||
# --instructions--
|
||||
|
||||
Transform the element on the screen to a heart. In the `heart::after` selector, change the `background-color` to `pink` and the `border-radius` to 50%.
|
||||
|
||||
Next, target the element with the class `heart` (just `heart`) and fill in the `transform` property. Use the `rotate()` function with -45 degrees.
|
||||
|
||||
Finally, in the `heart::before` selector, set its `content` property to an empty string.
|
||||
|
||||
# --hints--
|
||||
|
||||
The `background-color` property of the `heart::after` selector should be `pink`.
|
||||
|
||||
```js
|
||||
const heartAfter = code.match(/\.heart::after\s*{[\s\S]+?[^\}]}/g)[0];
|
||||
assert(
|
||||
/({|;)\s*background-color\s*:\s*pink\s*(;|})/g.test(heartAfter)
|
||||
);
|
||||
```
|
||||
|
||||
The `border-radius` of the `heart::after` selector should be 50%.
|
||||
|
||||
```js
|
||||
assert(code.match(/border-radius\s*?:\s*?50%/gi).length == 2);
|
||||
```
|
||||
|
||||
The `transform` property for the `heart` class should use a `rotate()` function set to -45 degrees.
|
||||
|
||||
```js
|
||||
assert(code.match(/transform\s*?:\s*?rotate\(\s*?-45deg\s*?\)/gi));
|
||||
```
|
||||
|
||||
The `content` of the `heart::before` selector should be an empty string.
|
||||
|
||||
```js
|
||||
assert(code.match(/\.heart::before\s*?{\s*?content\s*?:\s*?("|')\1\s*?;/gi));
|

title: Create Movement Using CSS Animation

# --description--
|
||||
|
||||
When elements have a specified `position`, such as `fixed` or `relative`, the CSS offset properties `right`, `left`, `top`, and `bottom` can be used in animation rules to create movement.
|
||||
|
||||
As shown in the example below, you can push the item downwards then upwards by setting the `top` property of the `50%` keyframe to 50px, but having it set to 0px for the first (`0%`) and the last (`100%`) keyframe.
|
||||
|
||||
```css
|
||||
@keyframes rainbow {
|
||||
0% {
|
||||
background-color: blue;
|
||||
top: 0px;
|
||||
}
|
||||
50% {
|
||||
background-color: green;
|
||||
top: 50px;
|
||||
}
|
||||
100% {
|
||||
background-color: yellow;
|
||||
top: 0px;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
# --instructions--
|
||||
|
||||
Add a horizontal motion to the `div` animation. Using the `left` offset property, add to the `@keyframes` rule so rainbow starts at 0 pixels at `0%`, moves to 25 pixels at `50%`, and ends at -25 pixels at `100%`. Don't replace the `top` property in the editor - the animation should have both vertical and horizontal motion.
|
||||
|
||||
# --hints--
|
||||
|
||||
The `@keyframes` rule for `0%` should use the `left` offset of 0px.
|
||||
|
||||
```js
|
||||
assert(code.match(/[^50]0%\s*?{[\s\S]*?left:\s*?0px(;[\s\S]*?|\s*?)}/gi));
|
||||
```
|
||||
|
||||
The `@keyframes` rule for `50%` should use the `left` offset of 25px.
|
||||
|
||||
```js
|
||||
assert(code.match(/50%\s*?{[\s\S]*?left:\s*?25px(;[\s\S]*?|\s*?)}/gi));
|
||||
```
|
||||
|
||||
The `@keyframes` rule for `100%` should use the `left` offset of -25px.
|
||||
|
||||
```js
|
||||
assert(code.match(/100%\s*?{[\s\S]*?left:\s*?-25px(;[\s\S]*?|\s*?)}/gi));
|
||||

title: Create Texture by Adding a Subtle Pattern as a Background Image

# --description--
|
||||
|
||||
One way to add texture and interest to a background and have it stand out more is to add a subtle pattern. The key is balance, as you don't want the background to stand out too much, and take away from the foreground. The `background` property supports the `url()` function in order to link to an image of the chosen texture or pattern. The link address is wrapped in quotes inside the parentheses.
|
||||
|
||||
# --instructions--
|
||||
|
||||
Using the url of `https://cdn-media-1.freecodecamp.org/imgr/MJAkxbh.png`, set the `background` of the whole page with the `body` selector.
|
||||
|
||||
# --hints--
|
||||
|
||||
Your `body` element should have a `background` property set to a `url()` with the given link.
|
||||
|
||||
```js
|
||||
assert(
|
||||
code.match(
|
||||
/background:\s*?url\(\s*("|'|)https:\/\/cdn-media-1\.freecodecamp\.org\/imgr\/MJAkxbh\.png\1\s*\)/gi

|

This section of the curriculum focuses on Applied Visual Design. The first group of challenges build on the given card layout to show a number of core principles.
|
||||
|
||||
Text is often a large part of web content. CSS has several options for how to align it with the `text-align` property.
|
||||
|
||||
`text-align: justify;` causes all lines of text except the last line to meet the left and right edges of the line box.
|
||||
|
||||
`text-align: center;` centers the text
|
||||
|
||||
`text-align: right;` right-aligns the text
|
||||
|
||||
And `text-align: left;` (the default) left-aligns the text.
|
||||
|
||||
# --instructions--
|
||||
|
||||
Align the `h4` tag's text, which says "Google", to the center. Then justify the paragraph tag which contains information about how Google was founded.
|
||||
|
||||
# --hints--
|
||||
|
||||
Your code should use the text-align property on the `h4` tag to set it to `center`.
|
||||
|
||||
```js
|
||||
assert($('h4').css('text-align') == 'center');
|
||||
```
|
||||
|
||||
Your code should use the text-align property on the `p` tag to set it to `justify`.
|
||||
|
||||
```js
|
||||
assert($('p').css('text-align') == 'justify');
|
||||
```

For this challenge, you'll change the `opacity` of an animated element so it gradually fades as it reaches the right side of the screen.
|
||||
|
||||
In the displayed animation, the round element with the gradient background moves to the right by the 50% mark of the animation per the `@keyframes` rule.
|
||||
|
||||
# --instructions--
|
||||
|
||||
Target the element with the id of `ball` and add the `opacity` property set to 0.1 at `50%`, so the element fades as it moves to the right.
|
||||
|
||||
# --hints--
|
||||
|
||||
The `keyframes` rule for fade should set the `opacity` property to 0.1 at 50%.
|
||||
|
||||
```js
|
||||
assert(
|
||||
code.match(
|
||||
/@keyframes fade\s*?{\s*?50%\s*?{\s*?(?:left:\s*?60%;\s*?opacity:\s*?0?\.1;|opacity:\s*?0?\.1;\s*?left:\s*?60%;)/gi

|
||||
|
||||
The `opacity` property in CSS is used to adjust the opacity, or conversely, the transparency for an item.
|
||||
|
||||
<blockquote>A value of 1 is opaque, which isn't transparent at all.<br>A value of 0.5 is half see-through.<br>A value of 0 is completely transparent.</blockquote>
|
||||
|
||||
The value given will apply to the entire element, whether that's an image with some transparency, or the foreground and background colors for a block of text.
|
||||
|
||||
# --instructions--
|
||||
|
||||
Set the `opacity` of the anchor tags to 0.7 using `links` class to select them.
|
||||
|
||||
# --hints--
|
||||
|
||||
Your code should set the `opacity` property to 0.7 on the anchor tags by selecting the class of `links`.
|
||||
|
||||
```js
|
||||
assert(
|
||||
/\.links\s*{([\s\S]*?;)*\s*opacity\s*:\s*0*\.70*\s*(;[\s\S]*?|\s*)}/.test(

|
||||
|
||||
Color theory and its impact on design is a deep topic and only the basics are covered in the following challenges. On a website, color can draw attention to content, evoke emotions, or create visual harmony. Using different combinations of colors can really change the look of a website, and a lot of thought can go into picking a color palette that works with your content.
|
||||
|
||||
The color wheel is a useful tool to visualize how colors relate to each other - it's a circle where similar hues are neighbors and different hues are farther apart. When two colors are opposite each other on the wheel, they are called complementary colors. They have the characteristic that if they are combined, they "cancel" each other out and create a gray color. However, when placed side-by-side, these colors appear more vibrant and produce a strong visual contrast.
|
||||
|
||||
Some examples of complementary colors with their hex codes are:
|
||||
|
||||
<blockquote>red (#FF0000) and cyan (#00FFFF)<br>green (#00FF00) and magenta (#FF00FF)<br>blue (#0000FF) and yellow (#FFFF00)</blockquote>
|
||||
|
||||
This is different than the outdated RYB color model that many of us were taught in school, which has different primary and complementary colors. Modern color theory uses the additive RGB model (like on a computer screen) and the subtractive CMY(K) model (like in printing). Read [here](https://en.wikipedia.org/wiki/Color_model) for more information on this complex subject.
|
||||
|
||||
There are many color picking tools available online that have an option to find the complement of a color.
|
||||
|
||||
**Note:** Using color can be a powerful way to add visual interest to a page. However, color alone should not be used as the only way to convey important information because users with visual impairments may not understand that content. This issue will be covered in more detail in the Applied Accessibility challenges.
|
||||
|
||||
# --instructions--
|
||||
|
||||
Change the `background-color` property of the `blue` and `yellow` classes to their respective colors. Notice how the colors look different next to each other than they do compared against the white background.
|
||||
|
||||
# --hints--
|
||||
|
||||
The `div` element with class `blue` should have a `background-color` of blue.
|
||||
|
||||
```js
|
||||
assert($('.blue').css('background-color') == 'rgb(0, 0, 255)');
|
||||
```
|
||||
|
||||
The `div` element with class `yellow` should have a `background-color` of yellow.
|
||||
|
||||
```js
|
||||
assert($('.yellow').css('background-color') == 'rgb(255, 255, 0)');
|
||||
```

title: Learn about Tertiary Colors

|

Computer monitors and device screens create different colors by combining amounts of red, green, and blue light. This is known as the RGB additive color model in modern color theory. Red (R), green (G), and blue (B) are called primary colors. Mixing two primary colors creates the secondary colors cyan (G + B), magenta (R + B) and yellow (R + G). You saw these colors in the Complementary Colors challenge. These secondary colors happen to be the complement to the primary color not used in their creation, and are opposite to that primary color on the color wheel. For example, magenta is made with red and blue, and is the complement to green.
|
||||
|
||||
Tertiary colors are the result of combining a primary color with one of its secondary color neighbors. For example, within the RGB color model, red (primary) and yellow (secondary) make orange (tertiary). This adds six more colors to a simple color wheel for a total of twelve.
|
||||
|
||||
There are various methods of selecting different colors that result in a harmonious combination in design. One example that can use tertiary colors is called the split-complementary color scheme. This scheme starts with a base color, then pairs it with the two colors that are adjacent to its complement. The three colors provide strong visual contrast in a design, but are more subtle than using two complementary colors.
|
||||
|
||||
Here are three colors created using the split-complement scheme:
|
||||
|
||||
<table class='table table-striped'><thead><tr><th>Color</th><th>Hex Code</th></tr></thead><thead></thead><tbody><tr><td>orange</td><td>#FF7F00</td></tr><tr><td>cyan</td><td>#00FFFF</td></tr><tr><td>raspberry</td><td>#FF007F</td></tr></tbody></table>
|
||||
|
||||
# --instructions--
|
||||
|
||||
Change the `background-color` property of the `orange`, `cyan`, and `raspberry` classes to their respective colors. Make sure to use the hex codes and not the color names.
|
||||
|
||||
# --hints--
|
||||
|
||||
The `div` element with class `orange` should have a `background-color` of orange.
|
||||
|
||||
```js
|
||||
assert($('.orange').css('background-color') == 'rgb(255, 127, 0)');
|
||||
```
|
||||
|
||||
The `div` element with class `cyan` should have a `background-color` of cyan.
|
||||
|
||||
```js
|
||||
assert($('.cyan').css('background-color') == 'rgb(0, 255, 255)');
|
||||
```
|
||||
|
||||
The `div` element with class `raspberry` should have a `background-color` of raspberry.
|
||||
|
||||
```js
|
||||
assert($('.raspberry').css('background-color') == 'rgb(255, 0, 127)');
|
||||
```
|
||||
|
||||
All `background-color` values for the color classes should be hex codes and not color names.
|
||||
|
||||
```js
|
||||
assert(!/background-color:\s(orange|cyan|raspberry)/.test(code));
|
||||

|

|
||||
The last challenge introduced the `animation-timing-function` property and a few keywords that change the speed of an animation over its duration. CSS offers an option other than keywords that provides even finer control over how the animation plays out, through the use of Bezier curves.
|
||||
|
||||
In CSS animations, Bezier curves are used with the `cubic-bezier` function. The shape of the curve represents how the animation plays out. The curve lives on a 1 by 1 coordinate system. The X-axis of this coordinate system is the duration of the animation (think of it as a time scale), and the Y-axis is the change in the animation.
|
||||
|
||||
The `cubic-bezier` function consists of four main points that sit on this 1 by 1 grid: `p0`, `p1`, `p2`, and `p3`. `p0` and `p3` are set for you - they are the beginning and end points which are always located respectively at the origin (0, 0) and (1, 1). You set the x and y values for the other two points, and where you place them in the grid dictates the shape of the curve for the animation to follow. This is done in CSS by declaring the x and y values of the `p1` and `p2` "anchor" points in the form: `(x1, y1, x2, y2)`. Pulling it all together, here's an example of a Bezier curve in CSS code:
|
||||
|
||||
```css
|
||||
animation-timing-function: cubic-bezier(0.25, 0.25, 0.75, 0.75);
|
||||
```
|
||||
|
||||
In the example above, the x and y values are equivalent for each point (x1 = 0.25 = y1 and x2 = 0.75 = y2), which if you remember from geometry class, results in a line that extends from the origin to point (1, 1). This animation is a linear change of an element during the length of an animation, and is the same as using the `linear` keyword. In other words, it changes at a constant speed.
|
||||
|
||||
# --instructions--
|
||||
|
||||
For the element with the id of `ball1`, change the value of the `animation-timing-function` property from `linear` to its equivalent `cubic-bezier` function value. Use the point values given in the example above.
|
||||
|
||||
# --hints--
|
||||
|
||||
The value of the `animation-timing-function` property for the element with the id `ball1` should be the linear-equivalent `cubic-bezier` function.
|
||||
|
||||
```js
|
||||
assert(
|
||||
$('#ball1').css('animation-timing-function') ==
|
||||
'cubic-bezier(0.25, 0.25, 0.75, 0.75)'
|
||||
);
|
||||
```
|
||||
|
||||
The value of the `animation-timing-function` property for the element with the id `ball2` should not change.
|
||||
|
||||
```js
|
||||
const ball2Animation = __helpers.removeWhiteSpace(
|
||||
$('#ball2').css('animation-timing-function')
|
||||
);
|
||||
assert(
|
||||
ball2Animation == 'ease-out' || ball2Animation == 'cubic-bezier(0,0,0.58,1)'
|
||||
);
|
||||
```

|

To animate an element, you need to know about the animation properties and the `@keyframes` rule. The animation properties control how the animation should behave and the `@keyframes` rule controls what happens during that animation. There are eight animation properties in total. This challenge will keep it simple and cover the two most important ones first:
|
||||
|
||||
`animation-name` sets the name of the animation, which is later used by `@keyframes` to tell CSS which rules go with which animations.
|
||||
|
||||
`animation-duration` sets the length of time for the animation.
|
||||
|
||||
`@keyframes` is how to specify exactly what happens within the animation over the duration. This is done by giving CSS properties for specific "frames" during the animation, with percentages ranging from 0% to 100%. If you compare this to a movie, the CSS properties for 0% is how the element displays in the opening scene. The CSS properties for 100% is how the element appears at the end, right before the credits roll. Then CSS applies the magic to transition the element over the given duration to act out the scene. Here's an example to illustrate the usage of `@keyframes` and the animation properties:
|
||||
|
||||
```css
|
||||
#anim {
|
||||
animation-name: colorful;
|
||||
animation-duration: 3s;
|
||||
}
|
||||
|
||||
@keyframes colorful {
|
||||
0% {
|
||||
background-color: blue;
|
||||
}
|
||||
100% {
|
||||
background-color: yellow;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
For the element with the `anim` id, the code snippet above sets the `animation-name` to `colorful` and sets the `animation-duration` to 3 seconds. Then the `@keyframes` rule links to the animation properties with the name `colorful`. It sets the color to blue at the beginning of the animation (0%) which will transition to yellow by the end of the animation (100%). You aren't limited to only beginning-end transitions, you can set properties for the element for any percentage between 0% and 100%.
|
||||
|
||||
# --instructions--
|
||||
|
||||
Create an animation for the element with the id `rect`, by setting the `animation-name` to `rainbow` and the `animation-duration` to 4 seconds. Next, declare a `@keyframes` rule, and set the `background-color` at the beginning of the animation (`0%`) to blue, the middle of the animation (`50%`) to green, and the end of the animation (`100%`) to yellow.
|
||||
|
||||
# --hints--
|
||||
|
||||
The element with id of `rect` should have an `animation-name` property with a value of `rainbow`.
|
||||
|
||||
```js
|
||||
assert($('#rect').css('animation-name') == 'rainbow');
|
||||
```
|
||||
|
||||
The element with id of `rect` should have an `animation-duration` property with a value of 4s.
|
||||
|
||||
```js
|
||||
assert($('#rect').css('animation-duration') == '4s');
|
||||
```
|
||||
|
||||
The `@keyframes` rule should use the `animation-name` of `rainbow`.
|
||||
|
||||
```js
|
||||
assert(code.match(/@keyframes\s+?rainbow\s*?{/g));
|
||||
```
|
||||
|
||||
The `@keyframes` rule for `rainbow` should use a `background-color` of `blue` at 0%.
|
||||
|
||||
```js
|
||||
assert(code.match(/0%\s*?{\s*?background-color:\s*?blue;\s*?}/gi));
|
||||
```
|
||||
|
||||
The `@keyframes` rule for `rainbow` should use a `background-color` of `green` at 50%.
|
||||
|
||||
```js
|
||||
assert(code.match(/50%\s*?{\s*?background-color:\s*?green;\s*?}/gi));
|
||||
```
|
||||
|
||||
The `@keyframes` rule for rainbow should use a `background-color` of `yellow` at 100%.
|
||||
|
||||
```js
|
||||
assert(code.match(/100%\s*?{\s*?background-color:\s*?yellow;\s*?}/gi));
|
||||

# --description--
|
||||
|
||||
The next option for the CSS `position` property is `absolute`, which locks the element in place relative to its parent container. Unlike the `relative` position, this removes the element from the normal flow of the document, so surrounding items ignore it. The CSS offset properties (top or bottom and left or right) are used to adjust the position.
|
||||
|
||||
One nuance with absolute positioning is that it will be locked relative to its closest *positioned* ancestor. If you forget to add a position rule to the parent item, (this is typically done using `position: relative;`), the browser will keep looking up the chain and ultimately default to the `body` tag.
|
||||
|
||||
# --instructions--
|
||||
|
||||
Lock the `#searchbar` element to the top-right of its `section` parent by declaring its `position` as `absolute`. Give it `top` and `right` offsets of 50 pixels each.
|
||||
|
||||
# --hints--
|
||||
|
||||
The `#searchbar` element should have a `position` set to `absolute`.
|
||||
|
||||
```js
|
||||
assert($('#searchbar').css('position') == 'absolute');
|
||||
```
|
||||
|
||||
Your code should use the `top` CSS offset of 50 pixels on the `#searchbar` element.
|
||||
|
||||
```js
|
||||
assert($('#searchbar').css('top') == '50px');
|
||||
```
|
||||
|
||||
Your code should use the `right` CSS offset of 50 pixels on the `#searchbar` element.
|
||||
|
||||
```js
|
||||
assert($('#searchbar').css('right') == '50px');
|
||||

title: Lock an Element to the Browser Window with Fixed Positioning

# --description--
|
||||
|
||||
The next layout scheme that CSS offers is the `fixed` position, which is a type of absolute positioning that locks an element relative to the browser window. Similar to absolute positioning, it's used with the CSS offset properties and also removes the element from the normal flow of the document. Other items no longer "realize" where it is positioned, which may require some layout adjustments elsewhere.
|
||||
|
||||
One key difference between the `fixed` and `absolute` positions is that an element with a fixed position won't move when the user scrolls.
|
||||
|
||||
# --instructions--
|
||||
|
||||
The navigation bar in the code is labeled with an id of `navbar`. Change its `position` to `fixed`, and offset it 0 pixels from the `top` and 0 pixels from the `left`. After you have added the code, scroll the preview window to see how the navigation stays in place.
|
||||
|
||||
# --hints--
|
||||
|
||||
The `#navbar` element should have a `position` set to `fixed`.
|
||||
|
||||
```js
|
||||
assert($('#navbar').css('position') == 'fixed');
|
||||
```
|
||||
|
||||
Your code should use the `top` CSS offset of 0 pixels on the `#navbar` element.
|
||||
|
||||
```js
|
||||
assert($('#navbar').css('top') == '0px');
|
||||
```
|
||||
|
||||
Your code should use the `left` CSS offset of 0 pixels on the `#navbar` element.
|
||||
|
||||
```js
|
||||
assert($('#navbar').css('left') == '0px');
|
||||

title: Make a CSS Heartbeat using an Infinite Animation Count
|
||||

# --description--
|
||||
|
||||
Here's one more continuous animation example with the `animation-iteration-count` property that uses the heart you designed in a previous challenge.
|
||||
|
||||
The one-second long heartbeat animation consists of two animated pieces. The `heart` elements (including the `:before` and `:after` pieces) are animated to change size using the `transform` property, and the background `div` is animated to change its color using the `background` property.
|
||||
|
||||
# --instructions--
|
||||
|
||||
Keep the heart beating by adding the `animation-iteration-count` property for both the `back` class and the `heart` class and setting the value to `infinite`. The `heart:before` and `heart:after` selectors do not need any animation properties.
|
||||
|
||||
# --hints--
|
||||
|
||||
The `animation-iteration-count` property for the `heart` class should have a value of `infinite`.
|
||||
|
||||
```js
|
||||
assert($('.heart').css('animation-iteration-count') == 'infinite');
|
||||
```
|
||||
|
||||
The `animation-iteration-count` property for the `back` class should have a value of `infinite`.
|
||||
|
||||
```js
|
||||
assert($('.back').css('animation-iteration-count') == 'infinite');
|
||||

title: Make Motion More Natural Using a Bezier Curve

|
||||
|
||||
This challenge animates an element to replicate the movement of a ball being juggled. Prior challenges covered the `linear` and `ease-out` cubic Bezier curves, however neither depicts the juggling movement accurately. You need to customize a Bezier curve for this.
|
||||
|
||||
The `animation-timing-function` automatically loops at every keyframe when the `animation-iteration-count` is set to infinite. Since there is a keyframe rule set in the middle of the animation duration (at `50%`), it results in two identical animation progressions at the upward and downward movement of the ball.
|
||||
|
||||
The following cubic Bezier curve simulates a juggling movement:
|
||||
|
||||
```css
|
||||
cubic-bezier(0.3, 0.4, 0.5, 1.6);
|
||||
```
|
||||
|
||||
Notice that the value of y2 is larger than 1. Although the cubic Bezier curve is mapped on a 1 by 1 coordinate system, and it can only accept x values from 0 to 1, the y value can be set to numbers larger than one. This results in a bouncing movement that is ideal for simulating the juggling ball.
|
||||
|
||||
# --instructions--
|
||||
|
||||
Change value of the `animation-timing-function` of the element with the id of `green` to a `cubic-bezier` function with x1, y1, x2, y2 values set respectively to 0.311, 0.441, 0.444, 1.649.

The value of the `animation-timing-function` property for the element with the id `green` should be a `cubic-bezier` function with x1, y1, x2, y2 values as specified.
|
||||
|

```js
|
||||
assert(
|
||||
$('#green').css('animation-timing-function') ==
|
||||
'cubic-bezier(0.311, 0.441, 0.444, 1.649)'
|

);

title: Modify Fill Mode of an Animation

|

|

That's great, but it doesn't work right yet. Notice how the animation resets after `500ms` has passed, causing the button to revert back to the original color. You want the button to stay highlighted.
|
||||
|
||||
This can be done by setting the `animation-fill-mode` property to `forwards`. The `animation-fill-mode` specifies the style applied to an element when the animation has finished. You can set it like so:
|
||||
|
||||
```css
|
||||
animation-fill-mode: forwards;
|
||||
```
|
||||
|
||||
# --instructions--
|
||||
|
||||
Set the `animation-fill-mode` property of `button:hover` to `forwards` so the button stays highlighted when a user hovers over it.
|
||||
|
||||
# --hints--
|
||||
|
||||
`button:hover` should have a `animation-fill-mode` property with a value of `forwards`.
|
||||
|
||||
```js
|
||||
assert(
|
||||
code.match(
|
||||
/button\s*?:\s*?hover\s*?{[\s\S]*animation-fill-mode\s*?:\s*?forwards\s*?;[\s\S]*}/gi
|
||||
) &&
|
||||
code.match(
|
||||
/button\s*?:\s*?hover\s*?{[\s\S]*animation-name\s*?:\s*?background-color\s*?;[\s\S]*}/gi
|
||||
) &&
|
||||
code.match(
|
||||
/button\s*?:\s*?hover\s*?{[\s\S]*animation-duration\s*?:\s*?500ms\s*?;[\s\S]*}/gi
|
||||

title: Move a Relatively Positioned Element with CSS Offsets

# --description--
|
||||
|
||||
The CSS offsets of `top` or `bottom`, and `left` or `right` tell the browser how far to offset an item relative to where it would sit in the normal flow of the document. You're offsetting an element away from a given spot, which moves the element away from the referenced side (effectively, the opposite direction). As you saw in the last challenge, using the `top` offset moved the `h2` downwards. Likewise, using a `left` offset moves an item to the right.
|
||||
|
||||

|
||||
|
||||
# --instructions--
|
||||
|
||||
Use CSS offsets to move the `h2` 15 pixels to the right and 10 pixels up.
|
||||
|
||||
# --hints--
|
||||
|
||||
Your code should use a CSS offset to relatively position the `h2` 10px upwards. In other words, move it 10px away from the `bottom` of where it normally sits.
|
||||
|
||||
```js
|
||||
assert($('h2').css('bottom') == '10px');
|
||||
```
|
||||
|
||||
Your code should use a CSS offset to relatively position the `h2` 15px towards the right. In other words, move it 15px away from the `left` of where it normally sits.
|
||||
|
||||
```js
|
||||
assert($('h2').css('left') == '15px');

title: Push Elements Left or Right with the float Property

# --description--
|
||||
|
||||
The next positioning tool does not actually use `position`, but sets the `float` property of an element. Floating elements are removed from the normal flow of a document and pushed to either the `left` or `right` of their containing parent element. It's commonly used with the `width` property to specify how much horizontal space the floated element requires.
|
||||
|
||||
# --instructions--
|
||||
|
||||
The given markup would work well as a two-column layout, with the `section` and `aside` elements next to each other. Give the `#left` item a `float` of `left` and the `#right` item a `float` of `right`.
|
||||
|
||||
# --hints--
|
||||
|
||||
The element with id `left` should have a `float` value of `left`.
|
||||
|
||||
```js
|
||||
assert($('#left').css('float') == 'left');
|
||||
```
|
||||
|
||||
The element with id `right` should have a `float` value of `right`.
|
||||
|
||||
```js
|
||||
assert($('#right').css('float') == 'right');

The `font-size` property is used to specify how large the text is in a given element. This rule can be used for multiple elements to create visual consistency of text on a page. In this challenge, you'll set the values for all `h1` through `h6` tags to balance the heading sizes.
|
||||
|
||||
# --instructions--
|
||||
|
||||
<p>In the <code>style</code> tags, set the <code>font-size</code> of the:</p>
|
||||
|
||||
<ul>
|
||||
<li><code>h1</code> tag to 68px.</li>
|
||||
<li><code>h2</code> tag to 52px.</li>
|
||||
<li><code>h3</code> tag to 40px.</li>
|
||||
<li><code>h4</code> tag to 32px.</li>
|
||||
<li><code>h5</code> tag to 21px.</li>
|
||||
<li><code>h6</code> tag to 14px.</li>
|
||||
</ul>
|
||||
|
||||
# --hints--
|
||||
|
||||
Your code should set the `font-size` property for the `h1` tag to 68 pixels.
|
||||
|
||||
```js
|
||||
assert($('h1').css('font-size') == '68px');
|
||||
```
|
||||
|
||||
Your code should set the `font-size` property for the `h2` tag to 52 pixels.
|
||||
|
||||
```js
|
||||
assert($('h2').css('font-size') == '52px');
|
||||
```
|
||||
|
||||
Your code should set the `font-size` property for the `h3` tag to 40 pixels.
|
||||
|
||||
```js
|
||||
assert($('h3').css('font-size') == '40px');
|
||||
```
|
||||
|
||||
Your code should set the `font-size` property for the `h4` tag to 32 pixels.
|
||||
|
||||
```js
|
||||
assert($('h4').css('font-size') == '32px');
|
||||
```
|
||||
|

|
||||
You set the `font-size` of each heading tag in the last challenge, here you'll adjust the `font-weight`.
|
||||
|
||||
The `font-weight` property sets how thick or thin characters are in a section of text.
|
||||
|
||||
# --instructions--
|
||||
|
||||
<ul><li>Set the <code>font-weight</code> of the <code>h1</code> tag to 800.</li><li>Set the <code>font-weight</code> of the <code>h2</code> tag to 600.</li><li>Set the <code>font-weight</code> of the <code>h3</code> tag to 500.</li><li>Set the <code>font-weight</code> of the <code>h4</code> tag to 400.</li><li>Set the <code>font-weight</code> of the <code>h5</code> tag to 300.</li><li>Set the <code>font-weight</code> of the <code>h6</code> tag to 200.</li></ul>
|
||||
|
||||
# --hints--
|
||||
|
||||
Your code should set the `font-weight` property for the `h1` tag to 800.
|
||||
|
||||
```js
|
||||
assert($('h1').css('font-weight') == '800');
|
||||
```
|
||||
|
||||
Your code should set the `font-weight` property for the `h2` tag to 600.
|
||||
|
||||
```js
|
||||
assert($('h2').css('font-weight') == '600');
|
||||
```
|
||||
|
||||
Your code should set the `font-weight` property for the `h3` tag to 500.
|
||||
|
||||
```js
|
||||
assert($('h3').css('font-weight') == '500');
|
||||
```
|
||||
|
||||
Your code should set the `font-weight` property for the `h4` tag to 400.
|
||||
|
||||
```js
|
||||
assert($('h4').css('font-weight') == '400');
|
||||
```
|
||||
|
||||
Your code should set the `font-weight` property for the `h5` tag to 300.
|
||||
|
||||
```js
|
||||
assert($('h5').css('font-weight') == '300');
|
||||
```
|
||||
|
||||
Your code should set the `font-weight` property for the `h6` tag to 200.
|
||||
|
||||
```js
|
||||
assert($('h6').css('font-weight') == '200');
|
||||
```

CSS offers the `line-height` property to change the height of each line in a block of text. As the name suggests, it changes the amount of vertical space that each line of text gets.
|
||||
|
||||
# --instructions--
|
||||
|
||||
Add a `line-height` property to the `p` tag and set it to 25px.
|
||||
|
||||
# --hints--
|
||||
|
||||
Your code should set the `line-height` of the `p` tag to 25 pixels.
|

title: Use a Bezier Curve to Move a Graphic

# --description--
|
||||
|
||||
A previous challenge discussed the `ease-out` keyword that describes an animation change that speeds up first and then slows down at the end of the animation. On the right, the difference between the `ease-out` keyword (for the blue element) and `linear` keyword (for the red element) is demonstrated. Similar animation progressions to the `ease-out` keyword can be achieved by using a custom cubic Bezier curve function.
|
||||
|
||||
In general, changing the `p1` and `p2` anchor points drives the creation of different Bezier curves, which controls how the animation progresses through time. Here's an example of a Bezier curve using values to mimic the ease-out style:
|
||||
|
||||
```css
|
||||
animation-timing-function: cubic-bezier(0, 0, 0.58, 1);
|
||||
```
|
||||
|
||||
Remember that all `cubic-bezier` functions start with `p0` at (0, 0) and end with `p3` at (1, 1). In this example, the curve moves faster through the Y-axis (starts at 0, goes to `p1` y value of 0, then goes to `p2` y value of 1) than it moves through the X-axis (0 to start, then 0 for `p1`, up to 0.58 for `p2`). As a result, the change in the animated element progresses faster than the time of the animation for that segment. Towards the end of the curve, the relationship between the change in x and y values reverses - the y value moves from 1 to 1 (no change), and the x values move from 0.58 to 1, making the animation changes progress slower compared to the animation duration.
|
||||
|
||||
# --instructions--
|
||||
|
||||
To see the effect of this Bezier curve in action, change the `animation-timing-function` of the element with id of `red` to a `cubic-bezier` function with x1, y1, x2, y2 values set respectively to 0, 0, 0.58, 1. This will make both elements progress through the animation similarly.
|
||||
|
||||
# --hints--
|
||||
|
||||
The value of the `animation-timing-function` property of the element with the id `red` should be a `cubic-bezier` function with x1, y1, x2, y2 values set respectively to 0, 0, 0.58, 1 .
|
||||
|
||||
```js
|
||||
assert(
|
||||
$('#red').css('animation-timing-function') == 'cubic-bezier(0, 0, 0.58, 1)'
|
||||
);
|
||||
```
|
||||
|
||||
The element with the id `red` should no longer have the `animation-timing-function` property of `linear`.
|
||||
|
||||
```js
|
||||
assert($('#red').css('animation-timing-function') !== 'linear');
|
||||
```
|
||||
|
||||
The value of the `animation-timing-function` property for the element with the id `blue` should not change.
|
||||
|
||||
```js
|
||||
const blueBallAnimation = __helpers.removeWhiteSpace(
|
||||
$('#blue').css('animation-timing-function')
|
||||
);
|
||||
assert(
|
||||
blueBallAnimation == 'ease-out' ||
|
||||
blueBallAnimation == 'cubic-bezier(0,0,0.58,1)'
|
||||
);
|

title: Use a CSS Linear Gradient to Create a Striped Element
|
||||

||||

|

|
||||
|
||||
# --description--
|
||||
|
||||
The `repeating-linear-gradient()` function is very similar to `linear-gradient()` with the major difference that it repeats the specified gradient pattern. `repeating-linear-gradient()` accepts a variety of values, but for simplicity, you'll work with an angle value and color stop values in this challenge.
|
||||
|
||||
The angle value is the direction of the gradient. Color stops are like width values that mark where a transition takes place, and are given with a percentage or a number of pixels.
|
||||
|
||||
In the example demonstrated in the code editor, the gradient starts with the color `yellow` at 0 pixels which blends into the second color `blue` at 40 pixels away from the start. Since the next color stop is also at 40 pixels, the gradient immediately changes to the third color `green`, which itself blends into the fourth color value `red` as that is 80 pixels away from the beginning of the gradient.
|
||||
|
||||
For this example, it helps to think about the color stops as pairs where every two colors blend together.
|
||||
|
||||
```css
|
||||
0px [yellow -- blend -- blue] 40px [green -- blend -- red] 80px
|
||||
```
|
||||
|
||||
If every two color stop values are the same color, the blending isn't noticeable because it's between the same color, followed by a hard transition to the next color, so you end up with stripes.
|
||||
|
||||
# --instructions--
|
||||
|
||||
Make stripes by changing the `repeating-linear-gradient()` to use a gradient angle of `45deg`, then set the first two color stops to `yellow`, and finally the second two color stops to `black`.
|
||||
|
||||
# --hints--
|
||||
|
||||
The angle of the `repeating-linear-gradient()` should be 45deg.
|
||||
|
||||
```js
|
||||
assert(code.match(/background:\s*?repeating-linear-gradient\(\s*?45deg/gi));
|
||||
```
|
||||
|
||||
The angle of the `repeating-linear-gradient()` should no longer be 90deg
|
||||
|
||||
```js
|
||||
assert(!code.match(/90deg/gi));
|
||||
```
|
||||
|
||||
The color stop at 0 pixels should be `yellow`.
|
||||
|
||||
```js
|
||||
assert(code.match(/yellow\s+?0(px)?/gi));
|
||||
```
|
||||
|
||||
One color stop at 40 pixels should be `yellow`.
|
||||
|
||||
```js
|
||||
assert(code.match(/yellow\s+?40px/gi));
|
||||
```
|
||||
|
||||
The second color stop at 40 pixels should be `black`.
|
||||
|
||||
```js
|
||||
assert(code.match(/yellow\s+?40px,\s*?black\s+?40px/gi));
|
||||
```
|
||||
|
||||
The last color stop at 80 pixels should be `black`.
|
||||
|
||||
```js
|
||||
assert(code.match(/black\s+?80px/gi));
|
||||
```

You can use CSS `@keyframes` to change the color of a button in its hover state.
|
||||
|
||||
Here's an example of changing the width of an image on hover:
|
||||
|
||||
```html
|
||||
<style>
|
||||
img:hover {
|
||||
animation-name: width;
|
||||
animation-duration: 500ms;
|
||||
}
|
||||
|
||||
@keyframes width {
|
||||
100% {
|
||||
width: 40px;
|
||||
}
|
||||
}
|
||||
</style>
|
||||
|
||||
<img src="https://bit.ly/smallgooglelogo" alt="Google's Logo" />
|
||||
```
|
||||
|
||||
# --instructions--
|
||||
|
||||
Note that `ms` stands for milliseconds, where 1000ms is equal to 1s.
|
||||
|
||||
Use CSS `@keyframes` to change the `background-color` of the `button` element so it becomes `#4791d0` when a user hovers over it. The `@keyframes` rule should only have an entry for `100%`.
|
||||
|
||||
# --hints--
|
||||
|
||||
The @keyframes rule should use the `animation-name` background-color.
|
||||
|
||||
```js
|
||||
assert(code.match(/@keyframes\s+?background-color\s*?{/g));
|
||||
```
|
||||
|
||||
There should be one rule under `@keyframes` that changes the `background-color` to `#4791d0` at 100%.
|
||||
|
||||
```js
|
||||
assert(code.match(/100%\s*?{\s*?background-color:\s*?#4791d0;\s*?}/gi));
|
||||
```

The next function of the `transform` property is `skewX()`, which skews the selected element along its X (horizontal) axis by a given degree.
|
||||
|
||||
The following code skews the paragraph element by -32 degrees along the X-axis.
|
||||
|
||||
```css
|
||||
p {
|
||||
transform: skewX(-32deg);
|
||||
}
|
||||
```
|
||||
|
||||
# --instructions--
|
||||
|
||||
Skew the element with the id of `bottom` by 24 degrees along the X-axis by using the `transform` property.
|
||||
|
||||
# --hints--
|
||||
|
||||
The element with id `bottom` should be skewed by 24 degrees along its X-axis.
|
||||
|
||||
```js
|
||||
assert(code.match(/#bottom\s*?{\s*?.*?\s*?transform:\s*?skewX\(24deg\);/g));
|

Given that the `skewX()` function skews the selected element along the X-axis by a given degree, it is no surprise that the `skewY()` property skews an element along the Y (vertical) axis.
|
||||
|
||||
# --instructions--
|
||||
|
||||
Skew the element with the id of `top` -10 degrees along the Y-axis by using the `transform` property.
|
||||
|
||||
# --hints--
|
||||
|
||||
The element with id `top` should be skewed by -10 degrees along its Y-axis.
|
||||
|
||||
```js
|
||||
assert(code.match(/#top\s*?{\s*?.*?\s*?transform:\s*?skewY\(-10deg\);/g));

To change the scale of an element, CSS has the `transform` property, along with its `scale()` function. The following code example doubles the size of all the paragraph elements on the page:
|
||||
|
||||
```css
|
||||
p {
|
||||
transform: scale(2);
|
||||
}
|
||||
```
|
||||
|
||||
# --instructions--
|
||||
|
||||
Increase the size of the element with the id of `ball2` to 1.5 times its original size.
|
||||
|
||||
# --hints--
|
||||
|
||||
The `transform` property for `#ball2` should be set to scale it to 1.5 times its size.
|
||||
|
||||
```js
|
||||
assert(
|
||||
code.match(
|
||||
/#ball2\s*?{\s*?left:\s*?65%;\s*?transform:\s*?scale\(1\.5\);\s*?}|#ball2\s*?{\s*?transform:\s*?scale\(1\.5\);\s*?left:\s*?65%;\s*?}/gi

|

The `transform` property has a variety of functions that let you scale, move, rotate, skew, etc., your elements. When used with pseudo-classes such as `:hover` that specify a certain state of an element, the `transform` property can easily add interactivity to your elements.
|
||||
|
||||
Here's an example to scale the paragraph elements to 2.1 times their original size when a user hovers over them:
|
||||
|
||||
```css
|
||||
p:hover {
|
||||
transform: scale(2.1);
|
||||
}
|
||||
```
|
||||
|
||||
**Note:** Applying a transform to a `div` element will also affect any child elements contained in the div.
|
||||
|
||||
# --instructions--
|
||||
|
||||
Add a CSS rule for the `hover` state of the `div` and use the `transform` property to scale the `div` element to 1.1 times its original size when a user hovers over it.
|
||||
|
||||
# --hints--
|
||||
|
||||
The size of the `div` element should scale 1.1 times when the user hovers over it.
|
||||
|
||||
```js
|
||||
assert(code.match(/div:hover\s*?{\s*?transform:\s*?scale\(1\.1\);/gi));
|
||||
```

|
||||
To emphasize text, you can use the `em` tag. This displays text as italicized, as the browser applies the CSS of `font-style: italic;` to the element.
|
||||
|
||||
# --instructions--
|
||||
|
||||
Wrap an `em` tag around the contents of the paragraph tag to give it emphasis.
|
||||
|
||||
# --hints--
|
||||
|
||||
Your code should add an `em` tag to the markup.
|
||||
|
||||
```js
|
||||
assert($('em').length == 1);
|
||||
```
|
||||
|
||||
The `em` tag should wrap around the contents of the `p` tag but not the `p` tag itself.
|
||||
|
||||
```js
|
||||
assert($('p').children().length == 1 && $('em').children().length == 2);
|
||||

# --description--
|
||||
|
||||
To strikethrough text, which is when a horizontal line cuts across the characters, you can use the `s` tag. It shows that a section of text is no longer valid. With the `s` tag, the browser applies the CSS of `text-decoration: line-through;` to the element.
|
||||
|
||||
# --instructions--
|
||||
|
||||
Wrap the `s` tag around `Google` inside the `h4` tag and then add the word `Alphabet` beside it, which should not have the strikethrough formatting.
|
||||
|
||||
# --hints--
|
||||
|
||||
Your code should add one `s` tag to the markup.
|
||||
|
||||
```js
|
||||
assert($('s').length == 1);
|
||||
```
|
||||
|
||||
A `s` tag should wrap around the `Google` text in the `h4` tag. It should not contain the word `Alphabet`.
|
||||
|
||||
```js
|
||||
assert(
|
||||
$('h4 > s')
|
||||
.text()
|
||||
.match(/Google/gi) &&
|
||||
!$('h4 > s')
|
||||
.text()
|
||||
.match(/Alphabet/gi)
|
||||
);
|
||||
```
|
||||
|
||||
You should include the word `Alphabet` in the `h4` tag, without strikethrough formatting.
|
||||
|
||||
```js
|
||||
assert(
|
||||
$('h4')
|
||||
.html()
|
||||
.match(/Alphabet/gi)

# --description--
|
||||
|
||||
To make text bold, you can use the `strong` tag. This is often used to draw attention to text and symbolize that it is important. With the `strong` tag, the browser applies the CSS of `font-weight: bold;` to the element.
|
||||
|
||||
# --instructions--
|
||||
|
||||
Wrap a `strong` tag around `Stanford University` text inside the `p` tag (do not include the period).
|
||||
|
||||
# --hints--
|
||||
|
||||
Your code should add one `strong` tag to the markup.
|
||||
|
||||
```js
|
||||
assert($('strong').length == 1);
|
||||
```
|
||||
|
||||
The `strong` tag should be inside the `p` tag.
|
||||
|
||||
```js
|
||||
assert($('p').children('strong').length == 1);
|
||||
```
|
||||
|
||||
The `strong` tag should wrap around the words `Stanford University`.
|
||||
|
||||
```js
|
||||
assert(
|
||||
$('strong')
|
||||
.text()
|
||||
.match(/^Stanford University\.?$/gi)
|
||||
);

# --description--
|
||||
|
||||
The `text-transform` property in CSS is used to change the appearance of text. It's a convenient way to make sure text on a webpage appears consistently, without having to change the text content of the actual HTML elements.
|
||||
|
||||
The following table shows how the different `text-transform`values change the example text "Transform me".
|
||||
|
||||
<table class='table table-striped'><thead><tr><th>Value</th><th>Result</th></tr></thead><tbody><tr><td><code>lowercase</code></td><td>"transform me"</td></tr><tr><td><code>uppercase</code></td><td>"TRANSFORM ME"</td></tr><tr><td><code>capitalize</code></td><td>"Transform Me"</td></tr><tr><td><code>initial</code></td><td>Use the default value</td></tr><tr><td><code>inherit</code></td><td>Use the <code>text-transform</code> value from the parent element</td></tr><tr><td><code>none</code></td><td><strong>Default:</strong> Use the original text</td></tr></tbody></table>
|
||||
|
||||
# --instructions--
|
||||
|
||||
Transform the text of the `h4` to be uppercase using the `text-transform` property.
|
||||
|
||||
# --hints--
|
||||
|
||||
The `h4` text should be `uppercase`.
|
||||
|
||||
```js
|
||||
assert($('h4').css('text-transform') === 'uppercase');
|
||||
```
|
||||
|
||||
The original text of the h4 should not be changed.
|
||||
|
||||
```js
|
||||
assert($('h4').text() !== $('h4').text().toUpperCase());
|
||||

# --description--
|
||||
|
||||
To underline text, you can use the `u` tag. This is often used to signify that a section of text is important, or something to remember. With the `u` tag, the browser applies the CSS of `text-decoration: underline;` to the element.
|
||||
|
||||
# --instructions--
|
||||
|
||||
Wrap the `u` tag only around the text `Ph.D. students`.
|
||||
|
||||
**Note:** Try to avoid using the `u` tag when it could be confused for a link. Anchor tags also have a default underlined formatting.
|
||||
|
||||
# --hints--
|
||||
|
||||
Your code should add a `u` tag to the markup.
|
||||
|
||||
```js
|
||||
assert($('u').length === 1);
|
||||
```
|
||||
|
||||
The `u` tag should wrap around the text `Ph.D. students`.
|
||||
|
||||
```js
|
||||
assert($('u').text() === 'Ph.D. students');

title: Add a Negative Margin to an Element

# --description--
|
||||
|
||||
An element's `margin` controls the amount of space between an element's `border` and surrounding elements.
|
||||
|
||||
If you set an element's `margin` to a negative value, the element will grow larger.
|
||||
|
||||
# --instructions--
|
||||
|
||||
Try to set the `margin` to a negative value like the one for the red box.
|
||||
|
||||
Change the `margin` of the blue box to `-15px`, so it fills the entire horizontal width of the yellow box around it.
|
||||
|
||||
# --hints--
|
||||
|
||||
Your `blue-box` class should give elements `-15px` of `margin`.
|
||||
|
||||
```js
|
||||
assert($('.blue-box').css('margin-top') === '-15px');
|
||||

# --description--
|
||||
|
||||
CSS borders have properties like `style`, `color` and `width`.
|
||||
|
||||
For example, if we wanted to create a red, 5 pixel border around an HTML element, we could use this class:
|
||||
|
||||
```html
|
||||
<style>
|
||||
.thin-red-border {
|
||||
border-color: red;
|
||||
border-width: 5px;
|
||||
border-style: solid;
|
||||
}
|
||||
</style>
|
||||
```
|
||||
|
||||
# --instructions--
|
||||
|
||||
Create a class called `thick-green-border`. This class should add a 10px, solid, green border around an HTML element. Apply the class to your cat photo.
|
||||
|
||||
Remember that you can apply multiple classes to an element using its `class` attribute, by separating each class name with a space. For example:
|
||||
|
||||
```html
|
||||
<img class="class1 class2">
|
||||
```
|
||||
|
||||
# --hints--
|
||||
|
||||
Your `img` element should have the class `smaller-image`.
|
||||
|
||||
```js
|
||||
assert($('img').hasClass('smaller-image'));
|
||||
```
|
||||
|
||||
Your `img` element should have the class `thick-green-border`.
|
||||
|
||||
```js
|
||||
assert($('img').hasClass('thick-green-border'));
|
||||
```
|
||||
|
||||
Your image should have a border width of `10px`.
|
||||
|
||||
```js
|
||||
assert(
|
||||
$('img').hasClass('thick-green-border') &&
|
||||
parseInt($('img').css('border-top-width'), 10) >= 8 &&
|
||||
parseInt($('img').css('border-top-width'), 10) <= 12
|
||||
);
|
||||
```
|
||||
|
||||
Your image should have a border style of `solid`.
|
||||
|
||||
```js
|
||||
assert($('img').css('border-right-style') === 'solid');
|
||||
```
|
||||
|
||||
The border around your `img` element should be green.
|
||||
|
||||
```js
|
||||
assert($('img').css('border-left-color') === 'rgb(0, 128, 0)');
|
||||
```

|

Sometimes you will want to customize an element so that it has a different `margin` on each of its sides.
|
||||
|
||||
CSS allows you to control the `margin` of all four individual sides of an element with the `margin-top`, `margin-right`, `margin-bottom`, and `margin-left` properties.
|
||||
|
||||
# --instructions--
|
||||
|
||||
Give the blue box a `margin` of `40px` on its top and left side, but only `20px` on its bottom and right side.
|
||||
|
||||
# --hints--
|
||||
|
||||
Your `blue-box` class should give the top of elements `40px` of `margin`.
|
||||
|
||||
```js
|
||||
assert($('.blue-box').css('margin-top') === '40px');
|
||||
```
|
||||
|
||||
Your `blue-box` class should give the right of elements `20px` of `margin`.
|
||||
|
||||
```js
|
||||
assert($('.blue-box').css('margin-right') === '20px');
|
||||
```
|
||||
|
||||
Your `blue-box` class should give the bottom of elements `20px` of `margin`.
|
||||
|
||||
```js
|
||||
assert($('.blue-box').css('margin-bottom') === '20px');
|
||||
```
|
||||
|
||||
Your `blue-box` class should give the left of elements `40px` of `margin`.
|
||||
|
||||
```js
|
||||
assert($('.blue-box').css('margin-left') === '40px');
|

# --description--
|
||||
|
||||
Your cat photo currently has sharp corners. We can round out those corners with a CSS property called `border-radius`.
|
||||
|
||||
# --instructions--
|
||||
|
||||
You can specify a `border-radius` with pixels. Give your cat photo a `border-radius` of `10px`.
|
||||
|
||||
**Note:** This challenge allows for multiple possible solutions. For example, you may add `border-radius` to either the `.thick-green-border` class or the `.smaller-image` class.
|
||||
|
||||
# --hints--
|
||||
|
||||
Your image element should have the class `thick-green-border`.
|
||||
|
||||
```js
|
||||
assert($('img').hasClass('thick-green-border'));
|
||||
```
|
||||
|
||||
Your image should have a border radius of `10px`.
|
||||
|
||||
```js
|
||||
assert(
|
||||
$('img').css('border-top-left-radius') === '10px' &&
|
||||
$('img').css('border-top-right-radius') === '10px' &&
|
||||
$('img').css('border-bottom-left-radius') === '10px' &&
|
||||
$('img').css('border-bottom-right-radius') === '10px'
|
||||
);
|
||||
```

|
||||
|
||||
An element's `margin` controls the amount of space between an element's `border` and surrounding elements.
|
||||
|
||||
Here, we can see that the blue box and the red box are nested within the yellow box. Note that the red box has a bigger `margin` than the blue box, making it appear smaller.
|
||||
|
||||
When you increase the blue box's `margin`, it will increase the distance between its border and surrounding elements.
|
||||
|
||||
# --instructions--
|
||||
|
||||
Change the `margin` of the blue box to match that of the red box.
|
||||
|
||||
# --hints--
|
||||
|
||||
Your `blue-box` class should give elements `20px` of `margin`.
|
||||
|
||||
```js
|
||||
assert($('.blue-box').css('margin-top') === '20px');
|
||||
```

|
||||
Now let's put our Cat Photo App away for a little while and learn more about styling HTML.
|
||||
|
||||
You may have already noticed this, but all HTML elements are essentially little rectangles.
|
||||
|
||||
Three important properties control the space that surrounds each HTML element: `padding`, `border`, and `margin`.
|
||||
|
||||
An element's `padding` controls the amount of space between the element's content and its `border`.
|
||||
|
||||
Here, we can see that the blue box and the red box are nested within the yellow box. Note that the red box has more `padding` than the blue box.
|
||||
|
||||
When you increase the blue box's `padding`, it will increase the distance (`padding`) between the text and the border around it.
|
||||
|
||||
# --instructions--
|
||||
|
||||
Change the `padding` of your blue box to match that of your red box.
|
||||
|
||||
# --hints--
|
||||
|
||||
Your `blue-box` class should give elements `20px` of `padding`.
|
||||
|
||||
```js
|
||||
assert($('.blue-box').css('padding-top') === '20px');
|
||||

title: Attach a Fallback value to a CSS Variable
|

# --description--
|
||||
|
||||
When using your variable as a CSS property value, you can attach a fallback value that your browser will revert to if the given variable is invalid.
|
||||
|
||||
**Note:** This fallback is not used to increase browser compatibility, and it will not work on IE browsers. Rather, it is used so that the browser has a color to display if it cannot find your variable.
|
||||
|
||||
Here's how you do it:
|
||||
|
||||
```css
|
||||
background: var(--penguin-skin, black);
|
||||
```
|
||||
|
||||
This will set background to `black` if your variable wasn't set. Note that this can be useful for debugging.
|
||||
|
||||
# --instructions--
|
||||
|
||||
It looks like there is a problem with the variables supplied to the `.penguin-top` and `.penguin-bottom` classes. Rather than fix the typo, add a fallback value of `black` to the `background` property of the `.penguin-top` and `.penguin-bottom` classes.
|
||||
|
||||
# --hints--
|
||||
|
||||
The fallback value of `black` should be used in the `background` property of the `penguin-top` class.
|
||||
|
||||
```js
|
||||
assert(
|
||||
code.match(
|
||||
/.penguin-top\s*?{[\s\S]*background\s*?:\s*?var\(\s*?--pengiun-skin\s*?,\s*?black\s*?\)\s*?;[\s\S]*}[\s\S]*.penguin-bottom\s{/gi
|
||||
)
|
||||
);
|
||||
```
|
||||
|
||||
The fallback value of `black` should be used in `background` property of the `penguin-bottom` class.
|
||||
|
||||
```js
|
||||
assert(
|
||||
code.match(
|
||||
/.penguin-bottom\s*?{[\s\S]*background\s*?:\s*?var\(\s*?--pengiun-skin\s*?,\s*?black\s*?\)\s*?;[\s\S]*}/gi

|
||||
|
||||
When you create your variables in `:root` they will set the value of that variable for the whole page.
|
||||
|
||||
You can then over-write these variables by setting them again within a specific element.
|
||||
|
||||
# --instructions--
|
||||
|
||||
Change the value of `--penguin-belly` to `white` in the `penguin` class.
|
||||
|
||||
# --hints--
|
||||
|
||||
The `penguin` class should reassign the `--penguin-belly` variable to `white`.
|
||||
|
||||
```js
|
||||
assert(
|
||||
code.match(/\.penguin\s*?{[\s\S]*--penguin-belly\s*?:\s*?white\s*?;[\s\S]*}/gi)
|
||||
);
|
||||
```
|
||||
|
||||
The `penguin` class should not contain the `background-color` property
|
||||
|
||||
```js
|
||||
assert(
|
||||
code.match(/^((?!background-color\s*?:\s*?)[\s\S])*$/g)
|
||||
);
|
||||
```

# --description--
|
||||
|
||||
Now let's change the color of some of our text.
|
||||
|
||||
We can do this by changing the `style` of your `h2` element.
|
||||
|
||||
The property that is responsible for the color of an element's text is the `color` style property.
|
||||
|
||||
Here's how you would set your `h2` element's text color to blue:
|
||||
|
||||
```html
|
||||
<h2 style="color: blue;">CatPhotoApp</h2>
|
||||
```
|
||||
|
||||
Note that it is a good practice to end inline `style` declarations with a `;` .
|
||||
|
||||
# --instructions--
|
||||
|
||||
Change your `h2` element's style so that its text color is red.
|
||||
|
||||
# --hints--
|
||||
|
||||
Your `h2` element should have a `style` declaration.
|
||||
|
||||
```js
|
||||
assert($('h2').attr('style'));
|
||||
```
|
||||
|
||||
Your `h2` element should have color set to `red`.
|
||||
|
||||
```js
|
||||
assert($('h2')[0].style.color === 'red');
|
||||
```
|
||||
|
||||
Your `style` declaration should end with a `;` .
|
||||
|
||||
```js
|
||||
assert($('h2').attr('style') && $('h2').attr('style').endsWith(';'));
|
||||
```

# --description--
|
||||
|
||||
Font size is controlled by the `font-size` CSS property, like this:
|
||||
|
||||
```css
|
||||
h1 {
|
||||
font-size: 30px;
|
||||
}
|
||||
```
|
||||
|
||||
# --instructions--
|
||||
|
||||
Inside the same `<style>` tag that contains your `red-text` class, create an entry for `p` elements and set the `font-size` to 16 pixels (`16px`).
|
||||
|
||||
# --hints--
|
||||
|
||||
Between the `style` tags, give the `p` elements `font-size` of `16px`. Browser and Text zoom should be at 100%.
|
||||
|
||||
```js
|
||||
assert(code.match(/p\s*{\s*font-size\s*:\s*16\s*px\s*;\s*}/i));

# --description--
|
||||
|
||||
To create a CSS variable, you just need to give it a name with two hyphens in front of it and assign it a value like this:
|
||||
|
||||
```css
|
||||
--penguin-skin: gray;
|
||||
```
|
||||
|
||||
This will create a variable named `--penguin-skin` and assign it the value of `gray`. Now you can use that variable elsewhere in your CSS to change the value of other elements to gray.
|
||||
|
||||
# --instructions--
|
||||
|
||||
In the `penguin` class, create a variable name `--penguin-skin` and give it a value of `gray`.
|
||||
|
||||
# --hints--
|
||||
|
||||
`penguin` class should declare the `--penguin-skin` variable and assign it to `gray`.
|
||||
|
||||
```js
|
||||
assert(
|
||||
code.match(/\.penguin\s*\{[^{}]*?--penguin-skin\s*:\s*gr[ae]y\s*;[^{}]*?\}/gi)
|
||||
);
|
||||
```

title: Give a Background Color to a div Element

# --description--
|
||||
|
||||
You can set an element's background color with the `background-color` property.
|
||||
|
||||
For example, if you wanted an element's background color to be `green`, you'd put this within your `style` element:
|
||||
|
||||
```css
|
||||
.green-background {
|
||||
background-color: green;
|
||||
}
|
||||
```
|
||||
|
||||
# --instructions--
|
||||
|
||||
Create a class called `silver-background` with the `background-color` of `silver`. Assign this class to your `div` element.
|
||||
|
||||
# --hints--
|
||||
|
||||
Your`div` element should have the class `silver-background`.
|
||||
|
||||
```js
|
||||
assert($('div').hasClass('silver-background'));
|
||||
```
|
||||
|
||||
Your `div` element should have a silver background.
|
||||
|
||||
```js
|
||||
assert($('div').css('background-color') === 'rgb(192, 192, 192)');
|
||||
```
|
||||
|
||||
A class named `silver-background` should be defined within the `style` element and the value of `silver` should be assigned to the `background-color` property.
|
||||
|
||||
```js
|
||||
assert(code.match(/\.silver-background\s*{\s*background-color\s*:\s*silver\s*;?\s*}/));
|
||||
```

# --description--
|
||||
|
||||
In addition to specifying common fonts that are found on most operating systems, we can also specify non-standard, custom web fonts for use on our website. There are many sources for web fonts on the Internet. For this example we will focus on the Google Fonts library.
|
||||
|
||||
[Google Fonts](https://fonts.google.com/) is a free library of web fonts that you can use in your CSS by referencing the font's URL.
|
||||
|
||||
So, let's go ahead and import and apply a Google font (note that if Google is blocked in your country, you will need to skip this challenge).
|
||||
|
||||
To import a Google Font, you can copy the font's URL from the Google Fonts library and then paste it in your HTML. For this challenge, we'll import the `Lobster` font. To do this, copy the following code snippet and paste it into the top of your code editor (before the opening `style` element):
|
||||
|
||||
```html
|
||||
<link href="https://fonts.googleapis.com/css?family=Lobster" rel="stylesheet" type="text/css">
|
||||
```
|
||||
|
||||
Now you can use the `Lobster` font in your CSS by using `Lobster` as the FAMILY_NAME as in the following example:
|
||||
|
||||
```css
|
||||
font-family: FAMILY_NAME, GENERIC_NAME;
|
||||
```
|
||||
|
||||
The GENERIC_NAME is optional, and is a fallback font in case the other specified font is not available. This is covered in the next challenge.
|
||||
|
||||
Family names are case-sensitive and need to be wrapped in quotes if there is a space in the name. For example, you need quotes to use the `"Open Sans"` font, but not to use the `Lobster` font.
|
||||
|
||||
# --instructions--
|
||||
|
||||
Import the `Lobster` font to your web page. Then, use an element selector to set `Lobster` as the `font-family` for your `h2` element.
|
||||
|
||||
# --hints--
|
||||
|
||||
You should import the `Lobster` font.
|
||||
|
||||
```js
|
||||
assert($('link[href*="googleapis" i]').length);
|
||||
```
|
||||
|
||||
Your `h2` element should use the font `Lobster`.
|
||||
|
||||
```js
|
||||
assert(
|
||||
$('h2')
|
||||
.css('font-family')
|
||||
.match(/lobster/i)
|
||||
);
|
||||
```
|
||||
|
||||
You should only use an `h2` element selector to change the font.
|
||||
|
||||
```js
|
||||
assert(
|
||||
/\s*[^\.]h2\s*\{\s*font-family\s*:\s*('|"|)Lobster\1\s*(,\s*('|"|)[a-z -]+\3\s*)?(;\s*\}|\})/gi.test(
|
||||

title: Improve Compatibility with Browser Fallbacks

# --description--
|
||||
|
||||
When working with CSS you will likely run into browser compatibility issues at some point. This is why it's important to provide browser fallbacks to avoid potential problems.
|
||||
|
||||
When your browser parses the CSS of a webpage, it ignores any properties that it doesn't recognize or support. For example, if you use a CSS variable to assign a background color on a site, Internet Explorer will ignore the background color because it does not support CSS variables. In that case, the browser will use whatever value it has for that property. If it can't find any other value set for that property, it will revert to the default value, which is typically not ideal.
|
||||
|
||||
This means that if you do want to provide a browser fallback, it's as easy as providing another more widely supported value immediately before your declaration. That way an older browser will have something to fall back on, while a newer browser will just interpret whatever declaration comes later in the cascade.
|
||||
|
||||
# --instructions--
|
||||
|
||||
It looks like a variable is being used to set the background color of the `.red-box` class. Let's improve our browser compatibility by adding another `background` declaration right before the existing declaration and set its value to `red`.
|
||||
|
||||
# --hints--
|
||||
|
||||
Your `.red-box` rule should include a fallback with the `background` set to `red` immediately before the existing `background` declaration.
|
||||
|
||||
```js
|
||||
assert(
|
||||
code
|
||||
.replace(/\s/g, '')
|
||||
.match(
|
||||
/\.red-box{background:(red|#ff0000|#f00|rgb\(255,0,0\)|rgb\(100%,0%,0%\)|hsl\(0,100%,50%\));background:var\(--red-color\);height:200px;width:200px;}/gi
|
||||
)
|
||||
);
|
||||
```

# --description--
|
||||
|
||||
When you create a variable, it is available for you to use inside the selector in which you create it. It also is available in any of that selector's descendants. This happens because CSS variables are inherited, just like ordinary properties.
|
||||
|
||||
To make use of inheritance, CSS variables are often defined in the <dfn>:root</dfn> element.
|
||||
|
||||
`:root` is a <dfn>pseudo-class</dfn> selector that matches the root element of the document, usually the `html` element. By creating your variables in `:root`, they will be available globally and can be accessed from any other selector in the style sheet.
|
||||
|
||||
# --instructions--
|
||||
|
||||
Define a variable named `--penguin-belly` in the `:root` selector and give it the value of `pink`. You can then see that the variable is inherited and that all the child elements which use it get pink backgrounds.
|
||||
|
||||
# --hints--
|
||||
|
||||
The `--penguin-belly` variable should be declared in the `:root` and assigned the value `pink`.
|
||||
|
||||
```js
|
||||
assert(
|
||||
code.match(/:root\s*?{[\s\S]*--penguin-belly\s*?:\s*?pink\s*?;[\s\S]*}/gi)
|

|
||||
|
||||
Now we've proven that every HTML page has a `body` element, and that its `body` element can also be styled with CSS.
|
||||
|
||||
Remember, you can style your `body` element just like any other HTML element, and all your other elements will inherit your `body` element's styles.
|
||||
|
||||
# --instructions--
|
||||
|
||||
First, create a `h1` element with the text `Hello World`
|
||||
|
||||
Then, let's give all elements on your page the color of `green` by adding `color: green;` to your `body` element's style declaration.
|
||||
|
||||
Finally, give your `body` element the font-family of `monospace` by adding `font-family: monospace;` to your `body` element's style declaration.
|
||||
|
||||
# --hints--
|
||||
|
||||
You should create an `h1` element.
|
||||
|
||||
```js
|
||||
assert($('h1').length > 0);
|
||||
```
|
||||
|
||||
Your `h1` element should have the text `Hello World`.
|
||||
|
||||
```js
|
||||
assert(
|
||||
$('h1').length > 0 &&
|
||||
$('h1')
|
||||
.text()
|
||||
.match(/hello world/i)
|
||||
);
|
||||
```
|
||||
|
||||
Your `h1` element should have a closing tag.
|
||||
|
||||
```js
|
||||
assert(
|
||||
code.match(/<\/h1>/g) &&
|
||||
code.match(/<h1/g) &&
|
||||
code.match(/<\/h1>/g).length === code.match(/<h1/g).length
|
||||
);
|
||||
```
|
||||
|
||||
Your `body` element should have the `color` property of `green`.
|
||||
|
||||
```js
|
||||
assert($('body').css('color') === 'rgb(0, 128, 0)');
|
||||
```
|
||||
|
||||
Your `body` element should have the `font-family` property of `monospace`.
|
||||
|
||||
```js
|
||||
assert(
|
||||
$('body')
|
||||
.css('font-family')
|
||||
.match(/monospace/i)
|
||||
);
|
||||
```
|
||||
|
||||
Your `h1` element should inherit the font `monospace` from your `body` element.
|
||||
|
||||
```js
|
||||
assert(
|
||||
$('h1').length > 0 &&
|
||||
$('h1')
|
||||
.css('font-family')
|
||||
.match(/monospace/i)
|
||||
);
|
||||
```
|
||||
|
||||
Your `h1` element should inherit the color green from your `body` element.
|
||||
|
||||
```js
|
||||
assert($('h1').length > 0 && $('h1').css('color') === 'rgb(0, 128, 0)');
|
||||
```

In addition to pixels, you can also specify the `border-radius` using a percentage.
|
||||
|
||||
# --instructions--
|
||||
|
||||
Give your cat photo a `border-radius` of `50%`.
|
||||
|
||||
# --hints--
|
||||
|
||||
Your image should have a border radius of `50%`, making it perfectly circular.
|
||||
|
||||
```js
|
||||
assert(parseInt($('img').css('border-top-left-radius')) > 48);
|
||||
```
|
||||
|
||||
The `border-radius` value should use a percentage value of `50%`.
|
||||
|
||||
```js
|
||||
assert(code.match(/50%/g));
|
||||
```

# --description--
|
||||
|
||||
Yay! We just proved that inline styles will override all the CSS declarations in your `style` element.
|
||||
|
||||
But wait. There's one last way to override CSS. This is the most powerful method of all. But before we do it, let's talk about why you would ever want to override CSS.
|
||||
|
||||
In many situations, you will use CSS libraries. These may accidentally override your own CSS. So when you absolutely need to be sure that an element has specific CSS, you can use `!important`.
|
||||
|
||||
Let's go all the way back to our `pink-text` class declaration. Remember that our `pink-text` class was overridden by subsequent class declarations, id declarations, and inline styles.
|
||||
|
||||
# --instructions--
|
||||
|
||||
Let's add the keyword `!important` to your pink-text element's color declaration to make 100% sure that your `h1` element will be pink.
|
||||
|
||||
An example of how to do this is:
|
||||
|
||||
```css
|
||||
color: red !important;
|
||||
```
|
||||
|
||||
# --hints--
|
||||
|
||||
Your `h1` element should have the class `pink-text`.
|
||||
|
||||
```js
|
||||
assert($('h1').hasClass('pink-text'));
|
||||
```
|
||||
|
||||
Your `h1` element should have the class `blue-text`.
|
||||
|
||||
```js
|
||||
assert($('h1').hasClass('blue-text'));
|
||||
```
|
||||
|
||||
Your `h1` element should have the `id` of `orange-text`.
|
||||
|
||||
```js
|
||||
assert($('h1').attr('id') === 'orange-text');
|
||||
```
|
||||
|
||||
Your `h1` element should have the inline style of `color: white`.
|
||||
|
||||
```js
|
||||
assert(code.match(/<h1.*style/gi) && code.match(/<h1.*style.*color\s*?:/gi));
|
||||
```
|
||||
|
||||
Your `pink-text` class declaration should have the `!important` keyword to override all other declarations.
|
||||
|
||||
```js
|
||||
assert(
|
||||
code.match(/\.pink-text\s*?\{[\s\S]*?color:.*pink.*!important\s*;?[^\.]*\}/g)
|
||||
);
|
||||
```
|
||||
|
||||
Your `h1` element should be pink.
|
||||
|
||||
```js
|
||||
assert($('h1').css('color') === 'rgb(255, 192, 203)');
|
||||
```

title: Override Class Declarations by Styling ID Attributes

# --description--
|
||||
|
||||
We just proved that browsers read CSS from top to bottom in order of their declaration. That means that, in the event of a conflict, the browser will use whichever CSS declaration came last. Notice that if we even had put `blue-text` before `pink-text` in our `h1` element's classes, it would still look at the declaration order and not the order of their use!
|
||||
|
||||
But we're not done yet. There are other ways that you can override CSS. Do you remember id attributes?
|
||||
|
||||
Let's override your `pink-text` and `blue-text` classes, and make your `h1` element orange, by giving the `h1` element an id and then styling that id.
|
||||
|
||||
# --instructions--
|
||||
|
||||
Give your `h1` element the `id` attribute of `orange-text`. Remember, id styles look like this:
|
||||
|
||||
```html
|
||||
<h1 id="orange-text">
|
||||
```
|
||||
|
||||
Leave the `blue-text` and `pink-text` classes on your `h1` element.
|
||||
|
||||
Create a CSS declaration for your `orange-text` id in your `style` element. Here's an example of what this looks like:
|
||||
|
||||
```css
|
||||
#brown-text {
|
||||
color: brown;
|
||||
}
|
||||
```
|
||||
|
||||
**Note:** It doesn't matter whether you declare this CSS above or below `pink-text` class, since the `id` attribute will always take precedence.
|
||||
|
||||
# --hints--
|
||||
|
||||
Your `h1` element should have the class `pink-text`.
|
||||
|
||||
```js
|
||||
assert($('h1').hasClass('pink-text'));
|
||||
```
|
||||
|
||||
Your `h1` element should have the class `blue-text`.
|
||||
|
||||
```js
|
||||
assert($('h1').hasClass('blue-text'));
|
||||
```
|
||||
|
||||
Your `h1` element should have the id of `orange-text`.
|
||||
|
||||
```js
|
||||
assert($('h1').attr('id') === 'orange-text');
|
||||
```
|
||||
|
||||
There should be only one `h1` element.
|
||||
|
||||
```js
|
||||
assert($('h1').length === 1);
|
||||
```
|
||||
|
||||
Your `orange-text` id should have a CSS declaration.
|
||||
|
||||
```js
|
||||
assert(code.match(/#orange-text\s*{/gi));
|
||||
```
|
||||
|
||||
Your `h1` should not have any `style` attributes.
|
||||
|
||||
```js
|
||||
assert(!code.match(/<h1.*style.*>/gi));
|
||||
```
|
||||
|
||||
Your `h1` element should be orange.
|
||||
|
||||
```js
|
||||
assert($('h1').css('color') === 'rgb(255, 165, 0)');

So we've proven that id declarations override class declarations, regardless of where they are declared in your `style` element CSS.
|
||||
|
||||
There are other ways that you can override CSS. Do you remember inline styles?
|
||||
|
||||
# --instructions--
|
||||
|
||||
Use an inline style to try to make our `h1` element white. Remember, inline styles look like this:
|
||||
|
||||
```html
|
||||
<h1 style="color: green;">
|
||||
```
|
||||
|
||||
Leave the `blue-text` and `pink-text` classes on your `h1` element.
|
||||
|
||||
# --hints--
|
||||
|
||||
Your `h1` element should have the class `pink-text`.
|
||||
|
||||
```js
|
||||
assert($('h1').hasClass('pink-text'));
|
||||
```
|
||||
|
||||
Your `h1` element should have the class `blue-text`.
|
||||
|
||||
```js
|
||||
assert($('h1').hasClass('blue-text'));
|
||||
```
|
||||
|
||||
Your `h1` element should have the id of `orange-text`.
|
||||
|
||||
```js
|
||||
assert($('h1').attr('id') === 'orange-text');
|
||||
```
|
||||
|
||||
Your `h1` element should have an inline style.
|
||||
|
||||
```js
|
||||
assert(document.querySelector('h1[style]'));
|
||||
```
|
||||
|
||||
Your `h1` element should be white.
|
||||
|
||||
```js
|

assert($('h1').css('color') === 'rgb(255, 255, 255)');

|
||||
Our `pink-text` class overrode our `body` element's CSS declaration!
|
||||
|
||||
We just proved that our classes will override the `body` element's CSS. So the next logical question is, what can we do to override our `pink-text` class?
|
||||
|
||||
# --instructions--
|
||||
|
||||
Create an additional CSS class called `blue-text` that gives an element the color blue. Make sure it's below your `pink-text` class declaration.
|
||||
|
||||
Apply the `blue-text` class to your `h1` element in addition to your `pink-text` class, and let's see which one wins.
|
||||
|
||||
Applying multiple class attributes to a HTML element is done with a space between them like this:
|
||||
|
||||
```html
|
||||
class="class1 class2"
|
||||
```
|
||||
|
||||
**Note:** It doesn't matter which order the classes are listed in the HTML element.
|
||||
|
||||
However, the order of the `class` declarations in the `<style>` section is what is important. The second declaration will always take precedence over the first. Because `.blue-text` is declared second, it overrides the attributes of `.pink-text`
|
||||
|
||||
# --hints--
|
||||
|
||||
Your `h1` element should have the class `pink-text`.
|
||||
|
||||
```js
|
||||
assert($('h1').hasClass('pink-text'));
|
||||
```
|
||||
|
||||
Your `h1` element should have the class `blue-text`.
|
||||
|
||||
```js
|
||||
assert($('h1').hasClass('blue-text'));
|
||||
```
|
||||
|
||||
Both `blue-text` and `pink-text` should belong to the same `h1` element.
|
||||
|
||||
```js
|
||||
assert($('.pink-text').hasClass('blue-text'));
|
||||
```
|
||||
|
||||
Your `h1` element should be blue.
|
||||
|
||||
```js
|
||||
assert($('h1').css('color') === 'rgb(0, 0, 255)');
|
||||
```

|
||||
Sometimes your HTML elements will receive multiple styles that conflict with one another.
|
||||
|
||||
For example, your `h1` element can't be both green and pink at the same time.
|
||||
|
||||
Let's see what happens when we create a class that makes text pink, then apply it to an element. Will our class *override* the `body` element's `color: green;` CSS property?
|
||||
|
||||
# --instructions--
|
||||
|
||||
Create a CSS class called `pink-text` that gives an element the color pink.
|
||||
|
||||
Give your `h1` element the class of `pink-text`.
|
||||
|
||||
# --hints--
|
||||
|
||||
Your `h1` element should have the class `pink-text`.
|
||||
|
||||
```js
|
||||
assert($('h1').hasClass('pink-text'));
|
||||
```
|
||||
|
||||
Your `<style>` should have a `pink-text` CSS class that changes the `color`.
|
||||
|
||||
```js
|
||||
assert(code.match(/\.pink-text\s*\{\s*color\s*:\s*.+\s*;?\s*\}/g));
|
||||
```
|
||||
|
||||
Your `h1` element should be pink.
|
||||
|
||||
```js
|
||||
assert($('h1').css('color') === 'rgb(255, 192, 203)');
|
||||
```

You can set which font an element should use, by using the `font-family` property.
|
||||
|
||||
For example, if you wanted to set your `h2` element's font to `sans-serif`, you would use the following CSS:
|
||||
|
||||
```css
|
||||
h2 {
|
||||
font-family: sans-serif;
|
||||
}
|
||||
```
|
||||
|
||||
# --instructions--
|
||||
|
||||
Make all of your `p` elements use the `monospace` font.
|
||||
|
||||
# --hints--
|
||||
|
||||
Your `p` elements should use the font `monospace`.
|
||||
|
||||
```js
|
||||
assert(
|
||||
$('p')
|
||||
.not('.red-text')
|
||||
.css('font-family')
|
||||
.match(/monospace/i)
|
||||
);
|
||||
```

|

In addition to classes, each HTML element can also have an `id` attribute.
|
||||
|
||||
There are several benefits to using `id` attributes: You can use an `id` to style a single element and later you'll learn that you can use them to select and modify specific elements with JavaScript.
|
||||
|
||||
`id` attributes should be unique. Browsers won't enforce this, but it is a widely agreed upon best practice. So please don't give more than one element the same `id` attribute.
|
||||
|
||||
Here's an example of how you give your `h2` element the id of `cat-photo-app`:
|
||||
|
||||
```html
|
||||
<h2 id="cat-photo-app">
|
||||
```
|
||||
|
||||
# --instructions--
|
||||
|
||||
Give your `form` element the id `cat-photo-form`.
|
||||
|
||||
# --hints--
|
||||
|
||||
Your `form` element should have the id of `cat-photo-form`.
|
||||
|
||||
```js
|
||||
assert($('form').attr('id') === 'cat-photo-form');
|
||||
```

|

|
||||
CSS has a property called `width` that controls an element's width. Just like with fonts, we'll use `px` (pixels) to specify the image's width.
|
||||
|
||||
For example, if we wanted to create a CSS class called `larger-image` that gave HTML elements a width of 500 pixels, we'd use:
|
||||
|
||||
```html
|
||||
<style>
|
||||
.larger-image {
|
||||
width: 500px;
|
||||
}
|
||||
</style>
|
||||
```
|
||||
|
||||
# --instructions--
|
||||
|
||||
Create a class called `smaller-image` and use it to resize the image so that it's only 100 pixels wide.
|
||||
|
||||
# --hints--
|
||||
|
||||
Your `img` element should have the class `smaller-image`.
|
||||
|
||||
```js
|
||||
assert(
|
||||
$("img[src='https://bit.ly/fcc-relaxing-cat']").attr('class')
|
||||
.trim().split(/\s+/g).includes('smaller-image')
|
||||
);
|
||||
```
|
||||
|
||||
Your image should be 100 pixels wide.
|
||||
|
||||
```js
|
||||
assert(
|
||||
$('img').width() < 200 &&
|
||||
code.match(/\.smaller-image\s*{\s*width\s*:\s*100px\s*(;\s*}|})/i)
|
||||
);
|
||||
```

title: Specify How Fonts Should Degrade

# --description--
|
||||
|
||||
There are several default fonts that are available in all browsers. These generic font families include `monospace`, `serif` and `sans-serif`.
|
||||
|
||||
When one font isn't available, you can tell the browser to "degrade" to another font.
|
||||
|
||||
For example, if you wanted an element to use the `Helvetica` font, but degrade to the `sans-serif` font when `Helvetica` isn't available, you will specify it as follows:
|
||||
|
||||
```css
|
||||
p {
|
||||
font-family: Helvetica, sans-serif;
|
||||
}
|
||||
```
|
||||
|
||||
Generic font family names are not case-sensitive. Also, they do not need quotes because they are CSS keywords.
|
||||
|
||||
# --instructions--
|
||||
|
||||
To begin, apply the `monospace` font to the `h2` element, so that it now has two fonts - `Lobster` and `monospace`.
|
||||
|
||||
In the last challenge, you imported the `Lobster` font using the `link` tag. Now comment out that import of the `Lobster` font (using the HTML comments you learned before) from Google Fonts so that it isn't available anymore. Notice how your `h2` element degrades to the `monospace` font.
|
||||
|
||||
**Note:** If you have the `Lobster` font installed on your computer, you won't see the degradation because your browser is able to find the font.
|
||||
|
||||
# --hints--
|
||||
|
||||
Your h2 element should use the font `Lobster`.
|
||||
|
||||
```js
|
||||
assert(
|
||||
$('h2')
|
||||
.css('font-family')
|
||||
.match(/^"?lobster/i)
|
||||
);
|
||||
```
|
||||
|
||||
Your h2 element should degrade to the font `monospace` when `Lobster` is not available.
|
||||
|
||||
```js
|
||||
assert(
|
||||
/\s*h2\s*\{\s*font-family\s*\:\s*(\'|"|)Lobster\1\s*,\s*monospace\s*;?\s*\}/gi.test(
|
||||
code
|
||||
)
|
||||
);
|
||||
```
|
||||
|
||||
You should comment out your call to Google for the `Lobster` font by putting `<!--` in front of it.
|
||||
|
||||
```js
|
||||
assert(new RegExp('<!--[^fc]', 'gi').test(code));
|
||||
```
|
||||
|
||||
You should close your comment by adding `-->`.
|
||||
|
||||
```js
|
||||
assert(new RegExp('[^fc]-->', 'gi').test(code));
|
||||
```

Classes allow you to use the same CSS styles on multiple HTML elements. You can see this by applying your `red-text` class to the first `p` element.
|
||||
|
||||
# --hints--
|
||||
|
||||
Your `h2` element should be red.
|
||||
|
||||
```js
|
||||
assert($('h2').css('color') === 'rgb(255, 0, 0)');
|
||||
```
|
||||
|
||||
Your `h2` element should have the class `red-text`.
|
||||
|
||||
```js
|
||||
assert($('h2').hasClass('red-text'));
|
||||
```
|
||||
|
||||
Your first `p` element should be red.
|
||||
|
||||
```js
|
||||
assert($('p:eq(0)').css('color') === 'rgb(255, 0, 0)');
|
||||
```
|
||||
|
||||
Your second and third `p` elements should not be red.
|
||||
|
||||
```js
|
||||
assert(
|
||||
!($('p:eq(1)').css('color') === 'rgb(255, 0, 0)') &&
|
||||
!($('p:eq(2)').css('color') === 'rgb(255, 0, 0)')
|
||||
);
|
||||
```
|
||||
|
||||
Your first `p` element should have the class `red-text`.
|
||||
|
||||
```js
|
||||
assert($('p:eq(0)').hasClass('red-text'));
|
||||

# --description--
|
||||
|
||||
Now let's start fresh and talk about CSS inheritance.
|
||||
|
||||
Every HTML page has a `body` element.
|
||||
|
||||
# --instructions--
|
||||
|
||||
We can prove that the `body` element exists here by giving it a `background-color` of black.
|
||||
|
||||
We can do this by adding the following to our `style` element:
|
||||
|
||||
```css
|
||||
body {
|
||||
background-color: black;
|
||||
}
|
||||
```
|
||||
|
||||
# --hints--
|
||||
|
||||
Your `body` element should have the `background-color` of black.
|
||||
|
||||
```js
|
||||
assert($('body').css('background-color') === 'rgb(0, 0, 0)');
|
||||
```
|
||||
|
||||
Your CSS rule should be properly formatted with both opening and closing curly brackets.
|
||||
|
||||
```js
|
||||
assert(
|
||||
code.match(/<style>\s*body\s*\{\s*background.*\s*:\s*.*;\s*\}\s*<\/style>/i)
|
||||
);
|
||||
```
|
||||
|
||||
Your CSS rule should end with a semi-colon.
|
||||
|
||||
```js
|
||||
assert(
|
||||
code.match(/<style>\s*body\s*\{\s*background.*\s*:\s*.*;\s*\}\s*<\/style>/i)
|
||||
);
|
||||
```

title: Understand Absolute versus Relative Units

# --description--
|
||||
|
||||
The last several challenges all set an element's margin or padding with pixels (`px`). Pixels are a type of length unit, which is what tells the browser how to size or space an item. In addition to `px`, CSS has a number of different length unit options that you can use.
|
||||
|
||||
The two main types of length units are absolute and relative. Absolute units tie to physical units of length. For example, `in` and `mm` refer to inches and millimeters, respectively. Absolute length units approximate the actual measurement on a screen, but there are some differences depending on a screen's resolution.
|
||||
|
||||
Relative units, such as `em` or `rem`, are relative to another length value. For example, `em` is based on the size of an element's font. If you use it to set the `font-size` property itself, it's relative to the parent's `font-size`.
|
||||
|
||||
**Note:** There are several relative unit options that are tied to the size of the viewport. They are covered in the Responsive Web Design Principles section.
|
||||
|
||||
# --instructions--
|
||||
|
||||
Add a `padding` property to the element with class `red-box` and set it to `1.5em`.
|
||||
|
||||
# --hints--
|
||||
|
||||
Your `red-box` class should have a `padding` property.
|
||||
|
||||
```js
|
||||
assert(
|
||||
$('.red-box').css('padding-top') != '0px' &&
|
||||
$('.red-box').css('padding-right') != '0px' &&
|
||||
$('.red-box').css('padding-bottom') != '0px' &&
|
||||
$('.red-box').css('padding-left') != '0px'
|
||||
);
|
||||
```
|
||||
|
||||
Your `red-box` class should give elements 1.5em of `padding`.
|
||||
|
||||
```js
|
||||
assert(code.match(/\.red-box\s*?{[\s\S]*padding\s*:\s*?1\.5em/gi));
|
||||
```

# --description--
|
||||
|
||||
Classes are reusable styles that can be added to HTML elements.
|
||||
|
||||
Here's an example CSS class declaration:
|
||||
|
||||
```html
|
||||
<style>
|
||||
.blue-text {
|
||||
color: blue;
|
||||
}
|
||||
</style>
|
||||
```
|
||||
|
||||
You can see that we've created a CSS class called `blue-text` within the `<style>` tag. You can apply a class to an HTML element like this: `<h2 class="blue-text">CatPhotoApp</h2>`. Note that in your CSS `style` element, class names start with a period. In your HTML elements' class attribute, the class name does not include the period.
|
||||
|
||||
# --instructions--
|
||||
|
||||
Inside your `style` element, change the `h2` selector to `.red-text` and update the color's value from `blue` to `red`.
|
||||
|
||||
Give your `h2` element the `class` attribute with a value of `red-text`.
|
||||
|
||||
# --hints--
|
||||
|
||||
Your `h2` element should be red.
|
||||
|
||||
```js
|
||||
assert($('h2').css('color') === 'rgb(255, 0, 0)');
|
||||
```
|
||||
|
||||
Your `h2` element should have the class `red-text`.
|
||||
|
||||
```js
|
||||
assert($('h2').hasClass('red-text'));
|
||||
```
|
||||
|
||||
Your stylesheet should declare a `red-text` class and have its color set to `red`.
|
||||
|
||||
```js
|
||||
assert(code.match(/\.red-text\s*\{\s*color\s*:\s*red;?\s*\}/g));
|
||||
```
|
||||
|
||||
You should not use inline style declarations like `style="color: red"` in your `h2` element.
|
||||
|
||||
```js
|
||||
assert($('h2').attr('style') === undefined);
|
||||
```

# --description--
|
||||
|
||||
After you create your variable, you can assign its value to other CSS properties by referencing the name you gave it.
|
||||
|
||||
```css
|
||||
background: var(--penguin-skin);
|
||||
```
|
||||
|
||||
This will change the background of whatever element you are targeting to gray because that is the value of the `--penguin-skin` variable. Note that styles will not be applied unless the variable names are an exact match.
|
||||
|
||||
# --instructions--
|
||||
|
||||
Apply the `--penguin-skin` variable to the `background` property of the `penguin-top`, `penguin-bottom`, `right-hand` and `left-hand` classes.
|
||||
|
||||
# --hints--
|
||||
|
||||
The `--penguin-skin` variable should be applied to the `background` property of the `penguin-top` class.
|
||||
|
||||
```js
|
||||
assert(
|
||||
code.match(
|
||||
/.penguin-top\s*?{[\s\S]*background\s*?:\s*?var\s*?\(\s*?--penguin-skin\s*?\)\s*?;[\s\S]*}[\s\S]*.penguin-bottom\s{/gi
|
||||
)
|
||||
);
|
||||
```
|
||||
|
||||
The `--penguin-skin` variable should be applied to the `background` property of the `penguin-bottom` class.
|
||||
|
||||
```js
|
||||
assert(
|
||||
code.match(
|
||||
/.penguin-bottom\s*?{[\s\S]*background\s*?:\s*?var\s*?\(\s*?--penguin-skin\s*?\)\s*?;[\s\S]*}[\s\S]*.right-hand\s{/gi
|
||||
)
|
||||
);
|
||||
```
|
||||
|
||||
The `--penguin-skin` variable should be applied to the `background` property of the `right-hand` class.
|
||||
|
||||
```js
|
||||
assert(
|
||||
code.match(
|
||||
/.right-hand\s*?{[\s\S]*background\s*?:\s*?var\s*?\(\s*?--penguin-skin\s*?\)\s*?;[\s\S]*}[\s\S]*.left-hand\s{/gi
|
||||
)
|
||||
);
|
||||
```
|
||||
|
||||
The `--penguin-skin` variable should be applied to the `background` property of the `left-hand` class.
|
||||
|
||||
```js
|
||||
assert(
|
||||
code.match(
|
||||
/.left-hand\s*?{[\s\S]*background\s*?:\s*?var\s*?\(\s*?--penguin-skin\s*?\)\s*?;[\s\S]*}/gi
|
||||
)
|
||||
);

||||

# --description--
|
||||
|
||||
CSS Variables can simplify the way you use media queries.
|
||||
|
||||
For instance, when your screen is smaller or larger than your media query break point, you can change the value of a variable, and it will apply its style wherever it is used.
|
||||
|
||||
# --instructions--
|
||||
|
||||
In the `:root` selector of the `media query`, change it so `--penguin-size` is redefined and given a value of `200px`. Also, redefine `--penguin-skin` and give it a value of `black`. Then resize the preview to see this change in action.
|
||||
|
||||
# --hints--
|
||||
|
||||
`:root` should reassign the `--penguin-size` variable to `200px`.
|
||||
|
||||
```js
|
||||
assert(
|
||||
code.match(
|
||||
/media\s*?\(\s*?max-width\s*?:\s*?350px\s*?\)\s*?{[\s\S]*:root\s*?{[\s\S]*--penguin-size\s*?:\s*?200px\s*?;[\s\S]*}[\s\S]*}/gi
|
||||
)
|
||||
);
|
||||
```
|
||||
|
||||
`:root` should reassign the `--penguin-skin` variable to `black`.
|
||||
|
||||
```js
|
||||
assert(
|
||||
code.match(

|
||||
|
||||
Many people feel overwhelmed by the possibilities of more than 16 million colors. And it's difficult to remember hex code. Fortunately, you can shorten it.
|
||||
|
||||
For example, red's hex code `#FF0000` can be shortened to `#F00`. This shortened form gives one digit for red, one digit for green, and one digit for blue.
|
||||
|
||||
This reduces the total number of possible colors to around 4,000. But browsers will interpret `#FF0000` and `#F00` as exactly the same color.
|
||||
|
||||
# --instructions--
|
||||
|
||||
Go ahead, try using the abbreviated hex codes to color the correct elements.
|
||||
|
||||
<table class='table table-striped'><tbody><tr><th>Color</th><th>Short Hex Code</th></tr><tr><td>Cyan</td><td><code>#0FF</code></td></tr><tr><td>Green</td><td><code>#0F0</code></td></tr><tr><td>Red</td><td><code>#F00</code></td></tr><tr><td>Fuchsia</td><td><code>#F0F</code></td></tr></tbody></table>
|
||||
|
||||
# --hints--
|
||||
|
||||
Your `h1` element with the text `I am red!` should be given the `color` red.
|
||||
|
||||
```js
|
||||
assert($('.red-text').css('color') === 'rgb(255, 0, 0)');
|
||||
```
|
||||
|
||||
The abbreviated `hex code` for the color red should be used instead of the hex code `#FF0000`.
|
||||
|
||||
```js
|
||||
assert(code.match(/\.red-text\s*?{\s*?color\s*:\s*?#F00\s*?;?\s*?}/gi));
|
||||
```
|
||||
|
||||
Your `h1` element with the text `I am green!` should be given the `color` green.
|
||||
|
||||
```js
|
||||
assert($('.green-text').css('color') === 'rgb(0, 255, 0)');
|
||||
```
|
||||
|
||||
The abbreviated `hex code` for the color green should be used instead of the hex code `#00FF00`.
|
||||
|
||||
```js
|
||||
assert(code.match(/\.green-text\s*?{\s*?color\s*:\s*?#0F0\s*?;?\s*?}/gi));
|
||||
```
|
||||
|
||||
Your `h1` element with the text `I am cyan!` should be given the `color` cyan.
|
||||
|
||||
```js
|
||||
assert($('.cyan-text').css('color') === 'rgb(0, 255, 255)');
|
||||
```
|
||||
|
||||
The abbreviated `hex code` for the color cyan should be used instead of the hex code `#00FFFF`.
|
||||
|
||||
```js
|
||||
assert(code.match(/\.cyan-text\s*?{\s*?color\s*:\s*?#0FF\s*?;?\s*?}/gi));
|
||||
```
|
||||
|
||||
Your `h1` element with the text `I am fuchsia!` should be given the `color` fuchsia.
|
||||
|
||||
```js
|
||||
assert($('.fuchsia-text').css('color') === 'rgb(255, 0, 255)');
|
||||
```
|
||||
|
||||
The abbreviated `hex code` for the color fuchsia should be used instead of the hex code `#FF00FF`.
|
||||
|
||||
```js
|
||||
assert(code.match(/\.fuchsia-text\s*?{\s*?color\s*:\s*?#F0F\s*?;?\s*?}/gi));

title: Use an id Attribute to Style an Element
|

# --description--
|
||||
|
||||
One cool thing about `id` attributes is that, like classes, you can style them using CSS.
|
||||
|
||||
However, an `id` is not reusable and should only be applied to one element. An `id` also has a higher specificity (importance) than a class so if both are applied to the same element and have conflicting styles, the styles of the `id` will be applied.
|
||||
|
||||
Here's an example of how you can take your element with the `id` attribute of `cat-photo-element` and give it the background color of green. In your `style` element:
|
||||
|
||||
```css
|
||||
#cat-photo-element {
|
||||
background-color: green;
|
||||
}
|
||||
```
|
||||
|
||||
Note that inside your `style` element, you always reference classes by putting a `.` in front of their names. You always reference ids by putting a `#` in front of their names.
|
||||
|
||||
# --instructions--
|
||||
|
||||
Try giving your form, which now has the `id` attribute of `cat-photo-form`, a green background.
|
||||
|
||||
# --hints--
|
||||
|
||||
Your `form` element should have the id of `cat-photo-form`.
|
||||
|
||||
```js
|
||||
assert($('form').attr('id') === 'cat-photo-form');
|
||||
```
|
||||
|
||||
Your `form` element should have the `background-color` of green.
|
||||
|
||||
```js
|
||||
assert($('#cat-photo-form').css('background-color') === 'rgb(0, 128, 0)');
|
||||
```
|
||||
|
||||
Your `form` element should have an `id` attribute.
|
||||
|
||||
```js
|
||||
assert(
|
||||
code.match(/<form.*cat-photo-form.*>/gi) &&
|
||||
code.match(/<form.*cat-photo-form.*>/gi).length > 0
|
||||
);
|
||||
```
|
||||
|
||||
You should not give your `form` any `class` or `style` attributes.
|
||||
|
||||
```js
|
||||
assert(!code.match(/<form.*style.*>/gi) && !code.match(/<form.*class.*>/gi));
|
||||
```

# --description--
|
||||
|
||||
You have been adding `id` or `class` attributes to elements that you wish to specifically style. These are known as ID and class selectors. There are other CSS Selectors you can use to select custom groups of elements to style.
|
||||
|
||||
Let's bring out CatPhotoApp again to practice using CSS Selectors.
|
||||
|
||||
For this challenge, you will use the `[attr=value]` attribute selector to style the checkboxes in CatPhotoApp. This selector matches and styles elements with a specific attribute value. For example, the below code changes the margins of all elements with the attribute `type` and a corresponding value of `radio`:
|
||||
|
||||
```css
|
||||
[type='radio'] {
|
||||
margin: 20px 0px 20px 0px;
|
||||
}
|
||||
```
|
||||
|
||||
# --instructions--
|
||||
|
||||
Using the `type` attribute selector, try to give the checkboxes in CatPhotoApp a top margin of 10px and a bottom margin of 15px.
|
||||
|
||||
# --hints--
|
||||
|
||||
The `type` attribute selector should be used to select the checkboxes.
|
||||
|
||||
```js
|
||||
assert(
|
||||
code.match(
|
||||
/<style>[\s\S]*?\[\s*?type\s*?=\s*?("|')checkbox\1\s*?\]\s*?{[\s\S]*?}[\s\S]*?<\/style>/gi
|
||||
)
|
||||
);
|
||||
```
|
||||
|
||||
The top margins of the checkboxes should be 10px.
|
||||
|
||||
```js
|
||||
assert(
|
||||
(function () {
|
||||
var count = 0;
|
||||
$("[type='checkbox']").each(function () {
|
||||
if ($(this).css('marginTop') === '10px') {
|
||||
count++;
|
||||
}
|
||||
});
|
||||
return count === 3;
|
||||
})()
|
||||
);
|
||||
```
|
||||
|
||||
The bottom margins of the checkboxes should be 15px.
|
||||
|
||||
```js
|
||||
assert(
|
||||
(function () {
|
||||
var count = 0;
|
||||
$("[type='checkbox']").each(function () {
|
||||
if ($(this).css('marginBottom') === '15px') {
|
||||
count++;
|
||||
}
|
||||
});
|
||||
return count === 3;
|
||||
})()
|
||||
);
|
||||
```

# --description--
|
||||
|
||||
Let's try this again, but with `margin` this time.
|
||||
|
||||
Instead of specifying an element's `margin-top`, `margin-right`, `margin-bottom`, and `margin-left` properties individually, you can specify them all in one line, like this:
|
||||
|
||||
```css
|
||||
margin: 10px 20px 10px 20px;
|
||||
```
|
||||
|
||||
These four values work like a clock: top, right, bottom, left, and will produce the exact same result as using the side-specific margin instructions.
|
||||
|
||||
# --instructions--
|
||||
|
||||
Use Clockwise Notation to give the element with the `blue-box` class a margin of `40px` on its top and left side, but only `20px` on its bottom and right side.
|
||||
|
||||
# --hints--
|
||||
|
||||
Your `blue-box` class should give the top of elements `40px` of `margin`.
|
||||
|
||||
```js
|
||||
assert($('.blue-box').css('margin-top') === '40px');
|
||||
```
|
||||
|
||||
Your `blue-box` class should give the right of elements `20px` of `margin`.
|
||||
|
||||
```js
|
||||
assert($('.blue-box').css('margin-right') === '20px');
|
||||
```
|
||||
|
||||
Your `blue-box` class should give the bottom of elements `20px` of `margin`.
|
||||
|
||||
```js
|
||||
assert($('.blue-box').css('margin-bottom') === '20px');
|
||||
```
|
||||
|
||||
Your `blue-box` class should give the left of elements `40px` of `margin`.
|
||||
|
||||
```js
|
||||
assert($('.blue-box').css('margin-left') === '40px');
|
||||
```
|
||||
|
||||
You should use the clockwise notation to set the margin of `blue-box` class.
|
||||
|
||||
```js
|
||||
assert(
|
||||
/\.blue-box\s*{[\s\S]*margin[\s]*:\s*\d+px\s+\d+px\s+\d+px\s+\d+px(;\s*[^}]+\s*}|;?\s*})/.test(
|
||||
__helpers.removeCssComments($('style').text())
|
||||
)
|
||||
);
|

# --description--
|
||||
|
||||
With CSS, there are hundreds of CSS properties that you can use to change the way an element looks on your page.
|
||||
|
||||
When you entered `<h2 style="color: red;">CatPhotoApp</h2>`, you were styling that individual `h2` element with inline CSS, which stands for Cascading Style Sheets.
|
||||
|
||||
That's one way to specify the style of an element, but there's a better way to apply CSS.
|
||||
|
||||
At the top of your code, create a `style` block like this:
|
||||
|
||||
```html
|
||||
<style>
|
||||
</style>
|
||||
```
|
||||
|
||||
Inside that style block, you can create a <dfn>CSS selector</dfn> for all `h2` elements. For example, if you wanted all `h2` elements to be red, you would add a style rule that looks like this:
|
||||
|
||||
```html
|
||||
<style>
|
||||
h2 {
|
||||
color: red;
|
||||
}
|
||||
</style>
|
||||
```
|
||||
|
||||
Note that it's important to have both opening and closing curly braces (`{` and `}`) around each element's style rule(s). You also need to make sure that your element's style definition is between the opening and closing style tags. Finally, be sure to add a semicolon to the end of each of your element's style rules.
|
||||
|
||||
# --instructions--
|
||||
|
||||
Delete your `h2` element's style attribute, and instead create a CSS `style` block. Add the necessary CSS to turn all `h2` elements blue.
|
||||
|
||||
# --hints--
|
||||
|
||||
The `style` attribute should be removed from your `h2` element.
|
||||
|
||||
```js
|
||||
assert(!$('h2').attr('style'));
|
||||
```
|
||||
|
||||
You should create a `style` element.
|
||||
|
||||
```js
|
||||
assert($('style') && $('style').length >= 1);
|
||||
```
|
||||
|
||||
Your `h2` element should be blue.
|
||||
|
||||
```js
|
||||
assert($('h2').css('color') === 'rgb(0, 0, 255)');
|
||||
```
|
||||
|
||||
Your stylesheet `h2` declaration should be valid with a semicolon and closing brace.
|
||||
|
||||
```js
|
||||
assert(code.match(/h2\s*\{\s*color\s*:.*;\s*\}/g));
|
||||
```
|
||||
|
||||
All your `style` elements should be valid and have closing tags.
|
||||
|
||||
```js
|
||||
assert(
|
||||
code.match(/<\/style>/g) &&
|
||||
code.match(/<\/style>/g).length ===
|
||||
(
|
||||
code.match(
|
||||
/<style((\s)*((type|media|scoped|title|disabled)="[^"]*")?(\s)*)*>/g
|
||||
) || []
|
||||
).length
|
||||
);
|
||||
```

# --description--
|
||||
|
||||
<dfn>CSS Variables</dfn> are a powerful way to change many CSS style properties at once by changing only one value.
|
||||
|
||||
Follow the instructions below to see how changing just three values can change the styling of many elements.
|
||||
|
||||
# --instructions--
|
||||
|
||||
In the `penguin` class, change the `black` value to `gray`, the `gray` value to `white`, and the `yellow` value to `orange`.
|
||||
|
||||
# --hints--
|
||||
|
||||
`penguin` class should declare the `--penguin-skin` variable and assign it to `gray`.
|
||||
|
||||
```js
|
||||
assert(
|
||||
code.match(/.penguin\s*?{[\s\S]*--penguin-skin\s*?:\s*?gray\s*?;[\s\S]*}/gi)
|
||||
);
|
||||
```
|
||||
|
||||
`penguin` class should declare the `--penguin-belly` variable and assign it to `white`.
|
||||
|
||||
```js
|
||||
assert(
|
||||
code.match(/.penguin\s*?{[\s\S]*--penguin-belly\s*?:\s*?white\s*?;[\s\S]*}/gi)
|
||||
);
|
||||
```
|
||||
|
||||
`penguin` class should declare the `--penguin-beak` variable and assign it to `orange`.
|
||||
|
||||
```js
|
||||
assert(
|
||||
code.match(/.penguin\s*?{[\s\S]*--penguin-beak\s*?:\s*?orange\s*?;[\s\S]*}/gi)
|
||||
);

|
||||
|
||||
Did you know there are other ways to represent colors in CSS? One of these ways is called hexadecimal code, or hex code for short.
|
||||
|
||||
We usually use <dfn>decimals</dfn>, or base 10 numbers, which use the symbols 0 to 9 for each digit. <dfn>Hexadecimals</dfn> (or <dfn>hex</dfn>) are base 16 numbers. This means it uses sixteen distinct symbols. Like decimals, the symbols 0-9 represent the values zero to nine. Then A,B,C,D,E,F represent the values ten to fifteen. Altogether, 0 to F can represent a digit in hexadecimal, giving us 16 total possible values. You can find more information about [hexadecimal numbers here](https://en.wikipedia.org/wiki/Hexadecimal).
|
||||
|
||||
In CSS, we can use 6 hexadecimal digits to represent colors, two each for the red (R), green (G), and blue (B) components. For example, `#000000` is black and is also the lowest possible value. You can find more information about the [RGB color system here](https://en.wikipedia.org/wiki/RGB_color_model).
|
||||
|
||||
```css
|
||||
body {
|
||||
color: #000000;
|
||||
}
|
||||
```
|
||||
|
||||
# --instructions--
|
||||
|
||||
Replace the word `black` in our `body` element's background-color with its hex code representation, `#000000`.
|
||||
|
||||
# --hints--
|
||||
|
||||
Your `body` element should have the background-color of black.
|
||||
|
||||
```js
|
||||
assert($('body').css('background-color') === 'rgb(0, 0, 0)');
|
||||
```
|
||||
|
||||
The `hex code` for the color black should be used instead of the word `black`.
|
||||
|
||||
```js
|
||||
assert(
|
||||
code.match(
|
||||
/body\s*{(([\s\S]*;\s*?)|\s*?)background.*\s*:\s*?#000(000)?((\s*})|(;[\s\S]*?}))/gi
|
||||
)
|
||||
);

To review, hex codes use 6 hexadecimal digits to represent colors, two each for red (R), green (G), and blue (B) components.
|
||||
|
||||
From these three pure colors (red, green, and blue), we can vary the amounts of each to create over 16 million other colors!

||||
|
||||
For example, orange is pure red, mixed with some green, and no blue. In hex code, this translates to being `#FFA500`.
|
||||
|
||||
The digit `0` is the lowest number in hex code, and represents a complete absence of color.
|
||||
|
||||
The digit `F` is the highest number in hex code, and represents the maximum possible brightness.
|
||||
|
||||

Just like with hex code, you can mix colors in RGB by using combinations of different values.
|
||||
|
||||
# --instructions--
|
||||
|
||||
Replace the hex codes in our `style` element with their correct RGB values.
|
||||
|
||||
<table class='table table-striped'><tbody><tr><th>Color</th><th>RGB</th></tr><tr><td>Blue</td><td><code>rgb(0, 0, 255)</code></td></tr><tr><td>Red</td><td><code>rgb(255, 0, 0)</code></td></tr><tr><td>Orchid</td><td><code>rgb(218, 112, 214)</code></td></tr><tr><td>Sienna</td><td><code>rgb(160, 82, 45)</code></td></tr></tbody></table>

|
||||
|
||||
Another way you can represent colors in CSS is by using `RGB` values.
|
||||
|
||||
The `RGB` value for black looks like this:
|
||||
|
||||
```css
|
||||
rgb(0, 0, 0)
|
||||
```
|
||||
|
||||
The `RGB` value for white looks like this:
|
||||
|
||||
```css
|
||||
rgb(255, 255, 255)
|
||||
```
|
||||
|
||||
Instead of using six hexadecimal digits like you do with hex code, with `RGB` you specify the brightness of each color with a number between 0 and 255.
|
||||
|
||||
If you do the math, the two digits for one color equal 16 times 16, which gives us 256 total values. So `RGB`, which starts counting from zero, has the exact same number of possible values as hex code.
|
||||
|
||||
Here's an example of how you'd change the `body` background to orange using its RGB code.
|
||||
|
||||
```css
|
||||
body {
|
||||
background-color: rgb(255, 165, 0);
|
||||
}
|
||||
```
|
||||
|
||||
# --instructions--
|
||||
|
||||
Let's replace the hex code in our `body` element's background color with the RGB value for black: `rgb(0, 0, 0)`
|
||||
|
||||
# --hints--
|
||||
|
||||
Your `body` element should have a black background.
|
||||
|
||||
```js
|
||||
assert($('body').css('background-color') === 'rgb(0, 0, 0)');
|
||||
```
|
||||
|
||||
You should use `rgb` to give your `body` element a background of black.
|
||||
|
||||
```js
|
||||
assert(code.match(/rgb\s*\(\s*0\s*,\s*0\s*,\s*0\s*\)/gi));
|
||||
```

title: Add Flex Superpowers to the Tweet Embed

To the right is the tweet embed that will be used as a practical example. Some of the elements would look better with a different layout. The last challenge demonstrated `display: flex`. Here you'll add it to several components in the tweet embed to start adjusting their positioning.
|
||||
|
||||
# --instructions--
|
||||
|
||||
Add the CSS property `display: flex` to all of the following items - note that the selectors are already set up in the CSS:
|
||||
|
||||
`header`, the header's `.profile-name`, the header's `.follow-btn`, the header's `h3` and `h4`, the `footer`, and the footer's `.stats`.
|
||||
|
||||
# --hints--
|
||||
|
||||
Your `.follow-btn` should be rendered on the page. Be sure to turn off any extensions such as ad blockers.
|
||||
|
||||
```js
|
||||
assert($('.follow-btn').length > 0 && $('.follow-btn').css('display') !== 'none');
|
||||
```
|
||||
|
||||
Your `header` should have a `display` property set to `flex`.
|
||||
|
||||
```js
|
||||
assert($('header').css('display') == 'flex');
|
||||
```
|
||||
|
||||
Your `footer` should have a `display` property set to `flex`.
|
||||
|
||||
```js
|
||||
assert($('footer').css('display') == 'flex');
|
||||
```
|
||||
|
||||
Your `h3` should have a `display` property set to `flex`.
|
||||
|
||||
```js
|
||||
assert($('h3').css('display') == 'flex');
|
||||
```
|
||||
|
||||
Your `h4` should have a `display` property set to `flex`.
|
||||
|
||||
```js
|
||||
assert($('h4').css('display') == 'flex');
|
||||
```
|
||||
|
||||
Your `.profile-name` should have a `display` property set to `flex`.
|
||||
|
||||
```js
|
||||
assert($('.profile-name').css('display') == 'flex');
|
||||
```
|
||||
|
||||
Your `.follow-btn` should have a `display` property set to `flex`.
|
||||
|
||||
```js
|
||||
assert($('.follow-btn').css('display') == 'flex');
|
||||
```
|
||||
|
||||
Your `.stats` should have a `display` property set to `flex`.
|
||||
|
||||
```js
|
||||
assert($('.stats').css('display') == 'flex');
|
||||
```

|

The `align-items` property is similar to `justify-content`. Recall that the `justify-content` property aligned flex items along the main axis. For rows, the main axis is a horizontal line and for columns it is a vertical line.
|
||||
|
||||
Flex containers also have a **cross axis** which is the opposite of the main axis. For rows, the cross axis is vertical and for columns, the cross axis is horizontal.
|
||||
|
||||
CSS offers the `align-items` property to align flex items along the cross axis. For a row, it tells CSS how to push the items in the entire row up or down within the container. And for a column, how to push all the items left or right within the container.
|
||||
|
||||
The different values available for `align-items` include:
|
||||
|
||||
<ul><li><code>flex-start</code>: aligns items to the start of the flex container. For rows, this aligns items to the top of the container. For columns, this aligns items to the left of the container.</li><li><code>flex-end</code>: aligns items to the end of the flex container. For rows, this aligns items to the bottom of the container. For columns, this aligns items to the right of the container.</li><li><code>center</code>: align items to the center. For rows, this vertically aligns items (equal space above and below the items). For columns, this horizontally aligns them (equal space to the left and right of the items).</li><li><code>stretch</code>: stretch the items to fill the flex container. For example, rows items are stretched to fill the flex container top-to-bottom. This is the default value if no <code>align-items</code> value is specified.</li><li><code>baseline</code>: align items to their baselines. Baseline is a text concept, think of it as the line that the letters sit on.</li></ul>

An example helps show this property in action. Add the CSS property `align-items` to the `#box-container` element, and give it a value of `center`.
|
||||
|
||||
**Bonus**
|
||||
Try the other options for the `align-items` property in the code editor to see their differences. But note that a value of `center` is the only one that will pass this challenge.
|
||||
|
||||
# --hints--
|
||||
|
||||
The `#box-container` element should have an `align-items` property set to a value of `center`.
|
||||
|
||||
```js
|
||||
assert($('#box-container').css('align-items') == 'center');
|

|

Sometimes the flex items within a flex container do not fill all the space in the container. It is common to want to tell CSS how to align and space out the flex items a certain way. Fortunately, the `justify-content` property has several options to do this. But first, there is some important terminology to understand before reviewing those options.
|
||||
|
||||
[Here is a useful image showing a row to illustrate the concepts below.](https://www.w3.org/TR/css-flexbox-1/images/flex-direction-terms.svg)
|
||||
|
||||
Recall that setting a flex container as a row places the flex items side-by-side from left-to-right. A flex container set as a column places the flex items in a vertical stack from top-to-bottom. For each, the direction the flex items are arranged is called the **main axis**. For a row, this is a horizontal line that cuts through each item. And for a column, the main axis is a vertical line through the items.
|
||||
|
||||
There are several options for how to space the flex items along the line that is the main axis. One of the most commonly used is `justify-content: center;`, which aligns all the flex items to the center inside the flex container. Other options include:
|
||||
|
||||
<ul><li><code>flex-start</code>: aligns items to the start of the flex container. For a row, this pushes the items to the left of the container. For a column, this pushes the items to the top of the container. This is the default alignment if no <code>justify-content</code> is specified.</li><li><code>flex-end</code>: aligns items to the end of the flex container. For a row, this pushes the items to the right of the container. For a column, this pushes the items to the bottom of the container.</li><li><code>space-between</code>: aligns items to the center of the main axis, with extra space placed between the items. The first and last items are pushed to the very edge of the flex container. For example, in a row the first item is against the left side of the container, the last item is against the right side of the container, then the remaining space is distributed evenly among the other items.</li><li><code>space-around</code>: similar to <code>space-between</code> but the first and last items are not locked to the edges of the container, the space is distributed around all the items with a half space on either end of the flex container.</li><li><code>space-evenly</code>: Distributes space evenly between the flex items with a full space at either end of the flex container</li></ul>

The tweet embed `header` and `footer` used the `flex-direction` property earlier with a row value. Similarly, the items inside the `.profile-name` element would work well stacked as a column.
|
||||
|
||||
# --instructions--
|
||||
|
||||
Add the CSS property `flex-direction` to the header's `.profile-name` element and set the value to `column`.
|
||||
|
||||
# --hints--
|
||||
|
||||
Your `.follow-btn` should be rendered on the page. Be sure to turn off any extensions such as ad blockers.
|
||||
|
||||
```js
|
||||
assert($('.follow-btn').length > 0 && $('.follow-btn').css('display') !== 'none');
|
||||
```
|
||||
|
||||
The `.profile-name` element should have a `flex-direction` property set to `column`.
|
||||
|
||||
```js
|
||||
assert($('.profile-name').css('flex-direction') == 'column');
|
||||

The `header` and `footer` in the tweet embed example have child items that could be arranged as rows using the `flex-direction` property. This tells CSS to align the children horizontally.
|
||||
|
||||
# --instructions--
|
||||
|
||||
Add the CSS property `flex-direction` to both the `header` and `footer` and set the value to `row`.
|
||||
|
||||
# --hints--
|
||||
|
||||
Your `.follow-btn` should be rendered on the page. Be sure to turn off any extensions such as ad blockers.
|
||||
|
||||
```js
|
||||
assert($('.follow-btn').length > 0 && $('.follow-btn').css('display') !== 'none');
|
||||
```
|
||||
|
||||
The `header` should have a `flex-direction` property set to `row`.
|
||||
|
||||
```js
|
||||
assert(code.match(/header\s*?{[^}]*?flex-direction:\s*?row;/g));
|
||||
```
|
||||
|
||||
The `footer` should have a `flex-direction` property set to `row`.
|
||||
|
||||
```js
|
||||
assert(code.match(/footer\s*?{[^}]*?flex-direction:\s*?row;/g));
|
||||
```
