Summary  
The chapter explains how the CSS flex-direction property specifies the orientation and flow direction (row, column, row-reverse, column-reverse) of items within a flex container.

General domain of usage  
Web page layout

The `flex-direction` property enables us to determine the direction in which flex items are arranged. By default, this property is set to `row`, resulting in a left-to-right layout in browsers that use English as the default language. You can set it to:
```css
flex-direction: row | column | row-reverse | column-reverse;
```

Let's consider the next website navigation as an example.
