Summary  
This chapter explains how to control the horizontal alignment and spacing of flex items along the main axis using the `justify-content` property with values such as `flex-start`, `flex-end`, `center`, `space-around`, and `space-between`.  

General domain of usage  
User interface layout (front-end development)

The `justify-content` property is instrumental in determining the position of flex items along the main axis. Its default value is `flex-start`.
```css
justify-content: flex-start | flex-end | center | space-between | space-around;
```


Let's consider each case on practice. We will play with the list of cards.

## flex-start
Default value, which makes all the items be at the start of the main axis.

## space-around
It distributes all the items evenly along the main axis with a bit of space left at either end.

## space-between
It is very similar to `space-around` except that it doesn't leave any space at the axis on both ends.
