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.
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.
<div class="d-flex">I'm a flexbox container!</div>
<div class="d-inline-flex">I'm an inline flexbox container!</div>
Responsive variations also exist for .d-flex
and .d-inline-flex
.
.d-sm-flex
.d-inline-flex
.d-sm-flex
.d-sm-inline-flex
.d-md-flex
.d-md-inline-flex
.d-lg-flex
.d-lg-inline-flex
.d-xl-flex
.d-xl-inline-flex
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 (the browser default), or .flex-row-reverse
to start the horizontal direction from the opposite side.
<div class="d-flex flex-row"></div>
<div class="d-flex flex-row-reverse"></div>
Use .flex-column
to set a vertical direction, or .flex-column-reverse
to start the vertical direction from the opposite side.
<div class="d-flex flex-column"></div>
<div class="d-flex flex-column-reverse"></div>
Responsive variations also exist for flex-direction
.

Change how flex items wrap in a flex container. Choose from no wrapping at all (the browser default) with .flex-nowrap
, wrapping with .flex-wrap
, or reverse wrapping with .flex-wrap-reverse
.

utilities to toggle a flex item’s ability to shrink if necessary. Use .flex-grow-*
utilities to toggle a flex item’s ability to grow to fill available space.
Responsive variations also exist for flex-shrink
and flex-grow
.

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
.
Heads up! This property has no effect on single rows of flex items.

<div class="d-flex flex-wrap align-content-center"></div>

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

(browser default).
<div class="d-flex align-items-start"></div>

). Choose from the same options as align-items: start

, center
, baseline
, or stretch
(browser default).

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 from 0 to 5, add custom CSS for any additional values needed.

<div class="order-3">First flex item</div>
<div class="order-2">Second flex item</div>
<div class="order-1">Third flex item</div>
</div>
