- When setting the direction, make sure to use the `flex-direction` attribute

Usage examples:

```html
<!-- Common vertical layout -->
<gds-flex flex-direction="column" gap="m">
  <!-- Content -->
</gds-flex>

<!-- Responsive horizontal/vertical layout -->
<gds-flex flex-direction="column;l{row}" gap="l">
  <!-- Content -->
</gds-flex>
```
