Quickly manage the layout, alignment, and sizing of grid columns, navigation, components, and more with a full suite of responsive flexbox utilities. For more complex implementations, custom CSS may be necessary.

## 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 %}
|
|
<div class="d-flex p-2 bd-highlight">I'm a flexbox container!</div>
|
|
{% endexample %}
|
|
|
|
{% example html %}
|
|
<div class="d-inline-flex p-2 bd-highlight">I'm an inline flexbox container!</div>
|
|
{% 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 %}
|
|
|
|
## 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 %}
|
|
<div class="d-flex flex-row bd-highlight">
|
|
<div class="p-2 bd-highlight">Flex item</div>
|
|
<div class="p-2 bd-highlight">Flex item</div>
|
|
<div class="p-2 bd-highlight">Flex item</div>
|
|
</div>
|
|
{% endexample %}
|
|
|
|
Use `.flex-column` to set a vertical direction.
|
|
|
|
{% example html %}
|
|
<div class="d-flex flex-column bd-highlight">
|
|
<div class="p-2 bd-highlight">Flex item</div>
|
|
<div class="p-2 bd-highlight">Flex item</div>
|
|
<div class="p-2 bd-highlight">Flex item</div>
|
|
</div>
|
|
{% endexample %}
|
|
|
|
Responsive variations also exist for `.flex-row` and `.flex-column`.
|
|
|
|
{% for bp in site.data.breakpoints %}
|
|
- `.flex{{ bp.abbr }}-row`
|
|
- `.flex{{ bp.abbr }}-column`{% endfor %}
|
|
|
|
## Wrap
|
|
|
|
Change how flex items wrap in a flex container. Choose from no wrapping at all (the browser default) with `.flex-nowrap`, or enable wrapping with `.flex-wrap`.
|
|
|
|
{% example html %}
|
|
<div class="d-flex flex-nowrap bd-highlight">
|
|
<div class="p-2 bd-highlight">Flex item</div>
|
|
<div class="p-2 bd-highlight">Flex item</div>
|
|
<div class="p-2 bd-highlight">Flex item</div>
|
|
<div class="p-2 bd-highlight">Flex item</div>
|
|
<div class="p-2 bd-highlight">Flex item</div>
|
|
<div class="p-2 bd-highlight">Flex item</div>
|
|
<div class="p-2 bd-highlight">Flex item</div>
|
|
<div class="p-2 bd-highlight">Flex item</div>
|
|
<div class="p-2 bd-highlight">Flex item</div>
|
|
<div class="p-2 bd-highlight">Flex item</div>
|
|
<div class="p-2 bd-highlight">Flex item</div>
|
|
<div class="p-2 bd-highlight">Flex item</div>
|
|
<div class="p-2 bd-highlight">Flex item</div>
|
|
<div class="p-2 bd-highlight">Flex item</div>
|
|
<div class="p-2 bd-highlight">Flex item</div>
|
|
</div>
|
|
{% endexample %}
|
|
|
|
{% example html %}
|
|
<div class="d-flex flex-wrap bd-highlight">
|
|
<div class="p-2 bd-highlight">Flex item</div>
|
|
<div class="p-2 bd-highlight">Flex item</div>
|
|
<div class="p-2 bd-highlight">Flex item</div>
|
|
<div class="p-2 bd-highlight">Flex item</div>
|
|
<div class="p-2 bd-highlight">Flex item</div>
|
|
<div class="p-2 bd-highlight">Flex item</div>
|
|
<div class="p-2 bd-highlight">Flex item</div>
|
|
<div class="p-2 bd-highlight">Flex item</div>
|
|
<div class="p-2 bd-highlight">Flex item</div>
|
|
<div class="p-2 bd-highlight">Flex item</div>
|
|
<div class="p-2 bd-highlight">Flex item</div>
|
|
<div class="p-2 bd-highlight">Flex item</div>
|
|
<div class="p-2 bd-highlight">Flex item</div>
|
|
<div class="p-2 bd-highlight">Flex item</div>
|
|
<div class="p-2 bd-highlight">Flex item</div>
|
|
</div>
|
|
{% endexample %}
|
|
|
|
Responsive variations also exist for `.flex-nowrap` and `.flex-wrap`.
|
|
|
|
{% for bp in site.data.breakpoints %}
|
|
- `.flex{{ bp.abbr }}-nowrap`
|
|
- `.flex{{ bp.abbr }}-wrap`{% endfor %}
