Summary  
This chapter explains the CSS Flexbox `justify-content` property for positioning and distributing flex items along the main (horizontal) axis using values like `flex-start`, `flex-end`, `center`, `space-between`, and `space-around`.  

General domain of usage  
Front-end web development

Egenskapen `justify-content` er avgjørende for å bestemme plasseringen av flex-elementer langs hovedaksen. Standardverdien er `flex-start`.
```css
justify-content: flex-start | flex-end | center | space-between | space-around;
```


La oss se på hvert tilfelle i praksis. Vi skal eksperimentere med en liste av kort.

## flex-start
Standardverdi som plasserer alle elementene ved starten av hovedaksen.
