Flex
Quickly manage the layout, alignment, and sizing of grid columns, navigation, components, and more with a full suite of responsive flexbox utilities.
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.
I'm a flexbox container!
html
<div class="d-flex p-2 border bg-light">I'm a flexbox container!</div>
I'm an inline flexbox container!
html
<div class="d-inline-flex p-2 border bg-light">I'm an inline flexbox container!</div>

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 (the browser default), or .flex-row-reverse
to start the horizontal direction from the opposite side.

Fill
Use the .flex-fill
class on a series of sibling elements to force them into widths equal to their content (or equal widths if their content does not surpass their border-boxes) while taking up all available horizontal space.

Grow and shrink
Use .flex-grow-*
utilities to toggle a flex item's ability to grow to fill available space. In the example below, the .flex-grow-1
elements uses all available space it can, while allowing the remaining two flex items their necessary space.

html
<div class="d-flex">

<div class="p-2 border bg-light">Flex item</div>
<div class="p-2 border bg-light">Third flex item</div>
</div>
Use .flex-shrink-*
utilities to toggle a flex item's ability to shrink if necessary. In the example below, the second flex item with .flex-shrink-1
is forced to wrap its contents to a new line, "shrinking" to allow more space for the previous flex item with .w-100
.

Auto margins
Flexbox can do some pretty awesome things when you mix flex alignments with auto margins. Shown below are three examples of controlling flex items via auto margins: default (no auto margin), pushing two items to the right (.me-auto
), and pushing two items to the left (.ms-auto
).

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

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 effect on single rows of flex items.

Media object
Create a media object component in no time with a few flex utilities that allow even more flexibility and customization than before.
This is some content from a media component. You can replace this with any content and adjust it as needed.
html
<div class="d-flex">
<div class="flex-shrink-0">
<img src="..." alt="..." />
</div>
<div class="flex-grow-1 ms-3">
This is some content from a media component. You can replace this with any content and adjust it as needed.
</div>
</div>
And say you want to vertically center the content next to the image:
