In this course, you will get hands-on experience in designing mobile-responsive web layouts using Flexbox. You will start with the basics like the Box Model and the process of layouting.

You will then move on to advanced concepts such as Flexbox containers, and aligning individual Flexbox items. Near the end of the course, you will put everything you just learned into practice. You will work on a project that focuses on developing a mobile-first website where you’ll experiment with page layout, headers, footers, and a lot more.

By the end of this course, you will be able to use Flexbox in your own projects to create beautiful layouts.

Designing Web Layouts with CSS and Flexbox

## Align-self options

The `align-items` rule determines how all Flex-items inside a Flex container are aligned on the cross-axis.

Sometimes there are exceptions to this rule. For instance, suppose there are blog post thumbnails centered on the cross-axis. However, as we put the mouse cursor over a Flex item, we would like to stretch that one blog post thumbnail. 

We can define similar exceptions on any Flex item using `align-self`. 

> The cross-axis alignment of a Flex item is determined as follows: 
>
> If there is an `align-self` rule defined on an individual Flex item, then this rule takes priority. Otherwise, the `align-items` property of the container determines the cross-axis alignment of the Flex item. 

There is one more caveat that determines if `align-self` has an effect on the cross-axis alignment of a Flex item: the Flex container has to have a defined cross-axis dimension. 

- For `row` or `row-reverse` Flexboxes, `height` has to be defined on the container.
- For `column` or `column-reverse` Flexboxes, `width` has to be defined on the container.

### `align-self` with horizontal `flex-direction`

Let's examine the possible values for `align-self` in the case of horizontal `flex-direction`:

In this lesson, we will look at the behavior of the align-self rule that determines the alignment of an individual Flex item on the cross axis.
