Summary  
This chapter covers the CSS Flexible Box Layout model, explaining how setting display:flex on a parent element turns it into a flex container that aligns and distributes its child items along axes with fine-grained control over size and order.

General domain of usage  
Web user interface layout

Flexbox, short for Flexible Box Layout, is a CSS module designed to simplify the alignment, distribution, and organization of elements within a container.

Flexbox uses a **parent-child relationship**. The **parent** is called the **flex container**, which controls the layout. The **children** are called **flex items**, whose size, position, and order can be controlled using flexbox properties.

> Note
>
> Flexbox behaves differently from block and inline elements. Unlike block elements, flex items do not stack vertically; they align in a row or column by default. Additionally, the margins at the edges of the container do not extend beyond its boundaries.

## Flexbox in Action
Flexbox works by aligning items along the **axes** of the flex container. To enable Flexbox, simply apply the `display: flex;` property to the parent element. From there, you can customize how the items align and distribute within the container.
