Summary  
This chapter covers how to use the CSS flex-direction property to control the axis (row or column) and ordering (normal or reversed) of flex items in a layout.

General domain of usage  
Website navigation layouts

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.
