Enable flex behaviors

Apply display utilities to create a flexbox container and transform direct children elements into flex items. Flex containers and items are able to be modified further with additional flex properties.

{% example html %}

I'm a flexbox container!

{% endexample %}

{% example html %}

I'm an inline flexbox container!

{% endexample %}

Responsive variations also exist for .d-flex and .d-inline-flex.

{% for bp in site.data.breakpoints %}

• .d{{ bp.abbr }}-flex
• .d{{ bp.abbr }}-inline-flex{% endfor %}

{% for bp in site.data.breakpoints %} {% endfor %} {% for bp in site.data.breakpoints %} {% endfor %}

Class	Description
.d{{ bp.abbr }}-flex	Sets display: flex; on viewports {{ bp.min-width }} wide and up
.d{{ bp.abbr }}-inline-flex	Sets display: inline-flex; on viewports {{ bp.min-width }} wide and up

Direction

Set the direction of flex items in a flex container with direction utilities. In most cases you can omit the horizontal class here as the browser default is row. However, you may encounter situations where you needed to explicitly set this value (like responsive layouts).

Use .flex-row to set a horizontal direction.

{% example html %}

Use .flex-column to set a vertical direction.
