An element's <code>margin</code> controls the amount of space between an element's <code>border</code> 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 <code>margin</code> than the blue box, making it appear smaller.
|

When you increase the blue box's <code>margin</code>, it will increase the distance between its border and surrounding elements.

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: <code>padding</code>, <code>border</code>, and <code>margin</code>.
|
||||
An element's <code>padding</code> controls the amount of space between the element's content and its <code>border</code>.
|
||||
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 <code>padding</code> than the blue box.
|
||||
When you increase the blue box's <code>padding</code>, it will increase the distance (<code>padding</code>) between the text and the border around it.
|
||||

|
||||

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.
|
||||
<strong>Note:</strong> 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.
|
||||

||||
**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.

Now let's change the color of some of our text.
|

We can do this by changing the <code>style</code> of your <code>h2</code> element.
|
||||
The property that is responsible for the color of an element's text is the <code>color</code> style property.
|
||||
Here's how you would set your <code>h2</code> element's text color to blue:

<code><h2 style="color: blue;">CatPhotoApp</h2></code>
|

Note that it is a good practice to end inline <code>style</code> declarations with a <code>;</code> .

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 <code>--penguin-skin</code> and assign it the value of <code>gray</code>.
|
||||
Now you can use that variable elsewhere in your CSS to change the value of other elements to gray.

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.
|
||||
<a href='https://fonts.google.com/' target='_blank'>Google Fonts</a> is a free library of web fonts that you can use in your CSS by referencing the font's URL.
|
||||
|
||||
[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 <code>Lobster</code> font. To do this, copy the following code snippet and paste it into the top of your code editor (before the opening <code>style</code> element):
|
||||
<code><link href="https://fonts.googleapis.com/css?family=Lobster" rel="stylesheet" type="text/css"></code>
|
||||
Now you can use the <code>Lobster</code> font in your CSS by using <code>Lobster</code> as the FAMILY_NAME as in the following example:<br><code>font-family: FAMILY_NAME, GENERIC_NAME;</code>.
|
||||
|
||||
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):
|
||||
|
||||
`<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:
|
||||
`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 <code>"Open Sans"</code> font, but not to use the <code>Lobster</code> font.
|
||||
</section>
|
||||
|
||||
## Instructions
|
||||
<section id='instructions'>
|
||||
Import the Lobster font to your web page. Then, use an element selector to set <code>Lobster</code> as the <code>font-family</code> for your <code>h2</code> element.
|
||||
</section>
|
||||
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.

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.

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.
|
||||
<code>:root</code> is a <dfn>pseudo-class</dfn> selector that matches the root element of the document, usually the <code>html</code> element. By creating your variables in <code>:root</code>, they will be available globally and can be accessed from any other selector in the style sheet.
|
||||
</section>
|
||||
|
||||
## Instructions
|
||||
<section id='instructions'>
|
||||
Define a variable named <code>--penguin-belly</code> in the <code>:root</code> selector and give it the value of <code>pink</code>. You can then see that the variable is inherited and that all the child elements which use it get pink backgrounds.

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 <code>!important</code>
|
||||
Let's go all the way back to our <code>pink-text</code> class declaration. Remember that our <code>pink-text</code> class was overridden by subsequent class declarations, id declarations, and inline styles.

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 <code>blue-text</code> before <code>pink-text</code> in our <code>h1</code> element's classes, it would still look at the declaration order and not the order of their use!

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.

Create an additional CSS class called <code>blue-text</code> that gives an element the color blue. Make sure it's below your <code>pink-text</code> class declaration.
|
||||
Apply the <code>blue-text</code> class to your <code>h1</code> element in addition to your <code>pink-text</code> 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:
|
||||
<code>class="class1 class2"</code>
|
||||
<strong>Note:</strong> It doesn't matter which order the classes are listed in the HTML element.
|
||||
However, the order of the <code>class</code> declarations in the <code><style></code> section is what is important. The second declaration will always take precedence over the first. Because <code>.blue-text</code> is declared second, it overrides the attributes of <code>.pink-text</code>

For example, your <code>h1</code> element can't be both green and pink at the same time.

In addition to classes, each HTML element can also have an <code>id</code> attribute.
|
||||
There are several benefits to using <code>id</code> attributes: You can use an <code>id</code> to style a single element and later you'll learn that you can use them to select and modify specific elements with JavaScript.
|
||||
<code>id</code> 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 <code>id</code> attribute.
|
||||
Here's an example of how you give your <code>h2</code> element the id of <code>cat-photo-app</code>:

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 <code>Helvetica</code> font, but degrade to the <code>sans-serif</code> font when <code>Helvetica</code> isn't available, you will specify it as follows:

To begin, apply the <code>monospace</code> font to the <code>h2</code> element, so that it now has two fonts - <code>Lobster</code> and <code>monospace</code>.
|
||||
In the last challenge, you imported the <code>Lobster</code> font using the <code>link</code> tag. Now comment out that import of the <code>Lobster</code> font (using the HTML comments you learned before) from Google Fonts so that it isn't available anymore. Notice how your <code>h2</code> element degrades to the <code>monospace</code> font.
|
||||
<strong>Note:</strong> 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.

To begin, apply the `monospace` font to the `h2` element, so that it now has two fonts - `Lobster` and `monospace`.
|
||||
|
||||
```yml
|
||||
tests:
|
||||
- text: Your h2 element should use the font <code>Lobster</code>.
|
||||
testString: assert($("h2").css("font-family").match(/^"?lobster/i));
|
||||
- text: Your h2 element should degrade to the font <code>monospace</code> when <code>Lobster</code> is not available.
|
||||
testString: assert(/\s*h2\s*\{\s*font-family\:\s*(\'|")?Lobster(\'|")?,\s*monospace\s*;\s*\}/gi.test(code));
|
||||
- text: You should comment out your call to Google for the <code>Lobster</code> font by putting <code><!--</code> in front of it.
|
||||
testString: assert(new RegExp("<!--[^fc]", "gi").test(code));
|
||||
- text: You should close your comment by adding <code>--></code>.
|
||||
testString: assert(new RegExp("[^fc]-->", "gi").test(code));
|
||||
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)
|
||||

|

```
|

## Description

The last several challenges all set an element's margin or padding with pixels (<code>px</code>). Pixels are a type of length unit, which is what tells the browser how to size or space an item. In addition to <code>px</code>, 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, <code>in</code> and <code>mm</code> 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 <code>em</code> or <code>rem</code>, are relative to another length value. For example, <code>em</code> is based on the size of an element's font. If you use it to set the <code>font-size</code> property itself, it's relative to the parent's <code>font-size</code>.
|
||||
<strong>Note:</strong> 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.

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
|
||||
<section id='instructions'>

||||
In the <code>:root</code> selector of the <code>media query</code>, change it so <code>--penguin-size</code> is redefined and given a value of <code>200px</code>. Also, redefine <code>--penguin-skin</code> and give it a value of <code>black</code>. Then resize the preview to see this change in action.

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 <code>#FF0000</code> can be shortened to <code>#F00</code>. 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 <code>#FF0000</code> and <code>#F00</code> as exactly the same color.

One cool thing about <code>id</code> attributes is that, like classes, you can style them using CSS.
|
||||
However, an <code>id</code> is not reusable and should only be applied to one element. An <code>id</code> 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 <code>id</code> will be applied.
|
||||
Here's an example of how you can take your element with the <code>id</code> attribute of <code>cat-photo-element</code> and give it the background color of green. In your <code>style</code> element:

Let's bring out CatPhotoApp again to practice using CSS Selectors.
|

For this challenge, you will use the <code>[attr=value]</code> 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 <code>type</code> and a corresponding value of <code>radio</code>:

Let's try this again, but with <code>margin</code> this time.
|

Instead of specifying an element's <code>margin-top</code>, <code>margin-right</code>, <code>margin-bottom</code>, and <code>margin-left</code> properties individually, you can specify them all in one line, like this:
|

<code>margin: 10px 20px 10px 20px;</code>

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 <a target='_blank' href='https://en.wikipedia.org/wiki/Hexadecimal'>hexadecimal numbers here</a>.
|
||||
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, <code>#000000</code> is black and is also the lowest possible value. You can find more information about the <a target='_blank' href='https://en.wikipedia.org/wiki/RGB_color_model'>RGB color system here</a>.

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 <code>#FFA500</code>.
|
||||
The digit <code>0</code> is the lowest number in hex code, and represents a complete absence of color.
|
||||
The digit <code>F</code> is the highest number in hex code, and represents the maximum possible brightness.

Your `h1` element with the text `I am sienna!` should have the `color` sienna.

```js
|

assert($('.sienna-text').css('color') === 'rgb(160, 82, 45)');
|
||||
```
|
||||
|

You should use `rgb` for the color sienna.

||||
```js
|
||||
assert(
|
||||
code.match(
|

/\.sienna-text\s*?{\s*?color:\s*?rgb\(\s*?160\s*?,\s*?82\s*?,\s*?45\s*?\)\s*?;\s*?}/gi

|

Another way you can represent colors in CSS is by using `RGB` values.
|
||||
|
||||
The RGB value for black looks like this:
|
||||
<code>rgb(0, 0, 0)</code>
|
||||
|
||||
`rgb(0, 0, 0)`
|
||||
|
||||
The RGB value for white looks like this:
|
||||
<code>rgb(255, 255, 255)</code>
|
||||
Instead of using six hexadecimal digits like you do with hex code, with <code>RGB</code> 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 <code>RGB</code>, which starts counting from zero, has the exact same number of possible values as hex code.

|
||||
