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 %}
{% example html %}
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 %}
Use .flex-column to set a vertical direction.
{% example html %}
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 %}
{% example html %}
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 %}
Justify content
Use justify-content utilities on flexbox containers to change the alignment of flex items on the main axis (the x-axis to start, y-axis if flex-direction: column). Choose from start (browser default), end, center, between, or around.
{% highlight html %}
Align items
Use align-items utilities on flexbox containers to change the alignment of flex items on the cross axis (the y-axis to start, x-axis if flex-direction: column). Choose from start, end, center, baseline, or stretch (browser default).
{% highlight html %}
Align self
Use align-self utilities on flexbox items to individually change their alignment on the cross axis (the y-axis to start, x-axis if flex-direction: column). Choose from the same options as align-items: start, end, center, baseline, or stretch (browser default).
{% highlight html %}
Order
Change the visual order of specific flex items with a handful of order utilities. We only provide options for making an item first or last, as well as a reset to use the DOM order. As order takes any integer value (e.g., 5), add custom CSS for any additional values needed.
{% example html %}
Align content
Use align-content utilities on flexbox containers to align flex items together on the cross axis. Choose from start (browser default), end, center, between, around, or stretch. To demonstrate these utilities, we've enforced flex-wrap: wrap and increased the number of flex items.
Heads up! This property has no affect on single rows of flex items.
