## Description
<section id='description'>
To the right is the tweet embed that will be used as the practical example. Some of the elements would look better with a different layout. The last challenge demonstrated <code>display: flex</code>. Here you'll add it to several components in the tweet embed to start adjusting their positioning.
</section>

## Instructions
<section id='instructions'>
Add the CSS property <code>display: flex</code> to all of the following items - note that the selectors are already set up in the CSS:
<code>header</code>, the header's <code>.profile-name</code>, the header's <code>.follow-btn</code>, the header's <code>h3</code> and <code>h4</code>, the <code>footer</code>, and the footer's <code>.stats</code>.

## Description
<section id='description'>
The <code>align-items</code> property is similar to <code>justify-content</code>. Recall that the <code>justify-content</code> 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 <strong>cross axis</strong> 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 <code>align-items</code> 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 <code>align-items</code> include:

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>

## Description
<section id='description'>
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 <code>justify-content</code> property has several options to do this. But first, there is some important terminology to understand before reviewing those options.
<a href="https://www.w3.org/TR/css-flexbox-1/images/flex-direction-terms.svg" target="_blank">Here is a useful image showing a row to illustrate the concepts below.</a>
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 <strong>main axis</strong>. 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 <code>justify-content: center;</code>, which aligns all the flex items to the center inside the flex container. Others options include:

This section uses alternating challenge styles to show how to use CSS to position elements in a flexible way. First, a challenge will explain theory, then a practical challenge using a simple tweet component will apply the flexbox concept.
Placing the CSS property <code>display: flex;</code> on an element allows you to use other flex properties to build a responsive page.

## Description
<section id='description'>
Adding <code>display: flex</code> to an element turns it into a flex container. This makes it possible to align any children of that element into rows or columns. You do this by adding the <code>flex-direction</code> property to the parent item and setting it to row or column. Creating a row will align the children horizontally, and creating a column will align the children vertically.
Other options for <code>flex-direction</code> are <code>row-reverse</code> and <code>column-reverse</code>.
<strong>Note:</strong> The default value for the <code>flex-direction</code> property is <code>row</code>.

The opposite of <code>flex-shrink</code> is the <code>flex-grow</code> property. Recall that <code>flex-shrink</code> controls the size of the items when the container shrinks. The <code>flex-grow</code> property controls the size of items when the parent container expands.
Using a similar example from the last challenge, if one item has a <code>flex-grow</code> value of <code>1</code> and the other has a <code>flex-grow</code> value of <code>3</code>, the one with the value of <code>3</code> will grow three times as much as the other.

## Description
<section id='description'>
There is a shortcut available to set several flex properties at once. The <code>flex-grow</code>, <code>flex-shrink</code>, and <code>flex-basis</code> properties can all be set together by using the <code>flex</code> property.
For example, <code>flex: 1 0 10px;</code> will set the item to <code>flex-grow: 1;</code>, <code>flex-shrink: 0;</code>, and <code>flex-basis: 10px;</code>.
The default property settings are <code>flex: 0 1 auto;</code>.
</section>
# --description--
## Instructions
<section id='instructions'>
Add the CSS property <code>flex</code> to both <code>#box-1</code> and <code>#box-2</code>. Give <code>#box-1</code> the values so its <code>flex-grow</code> is <code>2</code>, its <code>flex-shrink</code> is <code>2</code>, and its <code>flex-basis</code> is <code>150px</code>. Give <code>#box-2</code> the values so its <code>flex-grow</code> is <code>1</code>, its <code>flex-shrink</code> is <code>1</code>, and its <code>flex-basis</code> is <code>150px</code>.
These values will cause <code>#box-1</code> to grow to fill the extra space at twice the rate of <code>#box-2</code> when the container is greater than 300px and shrink at twice the rate of <code>#box-2</code> when the container is less than 300px. 300px is the combined size of the <code>flex-basis</code> values of the two boxes.

So far, all the properties in the challenges apply to the flex container (the parent of the flex items). However, there are several useful properties for the flex items.
The first is the <code>flex-shrink</code> property. When it's used, it allows an item to shrink if the flex container is too small. Items shrink when the width of the parent container is smaller than the combined widths of all the flex items within it.
The <code>flex-shrink</code> property takes numbers as values. The higher the number, the more it will shrink compared to the other items in the container. For example, if one item has a <code>flex-shrink</code> value of <code>1</code> and the other has a <code>flex-shrink</code> value of <code>3</code>, the one with the value of <code>3</code> will shrink three times as much as the other.

CSS flexbox has a feature to split a flex item into multiple rows (or columns). By default, a flex container will fit all flex items together. For example, a row will all be on one line.
However, using the <code>flex-wrap</code> property tells CSS to wrap items. This means extra items move into a new row or column. The break point of where the wrapping happens depends on the size of the items and the size of the container.
However, using the `flex-wrap` property tells CSS to wrap items. This means extra items move into a new row or column. The break point of where the wrapping happens depends on the size of the items and the size of the container.
CSS also has options for the direction of the wrap:
<ul><li><code>nowrap</code>: this is the default setting, and does not wrap items.</li><li><code>wrap</code>: wraps items from left-to-right if they are in a row, or top-to-bottom if they are in a column.</li><li><code>wrap-reverse</code>: wraps items from right-to-left if they are in a row, or bottom-to-top if they are in a column.</li></ul>
