Angular Bootstrap flexbox is a utility for managing position of the items in container and distribute space between them in a more efficient way.
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.
<div class="d-flex p-2 col-example">I'm a flexbox container!</div>
<div class="d-inline-flex p-2 col-example">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.
<div class="d-flex flex-row">
<div class="p-2">Flex item 1</div>
<div class="p-2">Flex item 2</div>
<div class="p-2">Flex item 3</div>
</div>
<div class="d-flex flex-row-reverse">
<div class="p-2">Flex item 1</div>
<div class="p-2">Flex item 2</div>
<div class="p-2">Flex item 3</div>
</div>
<div class="d-flex flex-column">
<div class="p-2">Flex item 1</div>
<div class="p-2">Flex item 2</div>
<div class="p-2">Flex item 3</div>
</div>
<div class="d-flex flex-column-reverse">
<div class="p-2">Flex item 1</div>
<div class="p-2">Flex item 2</div>
<div class="p-2">Flex item 3</div>
</div>
Responsive variations also exist for
flex-direction.

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.
<div class="d-flex justify-content-start">...</div>
<div class="d-flex justify-content-end">...</div>
<div class="d-flex justify-content-center">...</div>
<div class="d-flex justify-content-between">...</div>
<div class="d-flex justify-content-around">...</div>

justify-content.

.justify-content-lg-around -
.justify-content-xl-start -
.justify-content-xl-end -
.justify-content-xl-center -
.justify-content-xl-between -
.justify-content-xl-around
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).
<div class="d-flex align-items-start">...</div>
<div class="d-flex align-items-end">...</div>
<div class="d-flex align-items-center">...</div>
<div class="d-flex align-items-baseline">...</div>
<div class="d-flex align-items-stretch">...</div>
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).
<div class="align-self-start">Aligned flex item</div>
<div class="align-self-end">Aligned flex item</div>
<div class="align-self-center">Aligned flex item</div>
<div class="align-self-baseline">Aligned flex item</div>
<div class="align-self-stretch">Aligned flex item</div>
Responsive variations also exist for
align-self.

.align-self-end -
.align-self-center -
.align-self-baseline -
.align-self-stretch -
.align-self-sm-start -
.align-self-sm-end -

.align-self-sm-baseline -
.align-self-sm-stretch -
.align-self-md-start -
.align-self-md-end -
.align-self-md-center -
.align-self-md-baseline -
.align-self-md-stretch -
.align-self-lg-start -
.align-self-lg-end -
.align-self-lg-center -
.align-self-lg-baseline -
.align-self-lg-stretch -
.align-self-xl-start -
.align-self-xl-end -
.align-self-xl-center -
.align-self-xl-baseline -
.align-self-xl-stretch
Fill
Use the
.flex-fill class on a series of sibling elements to force them into equal widths while taking up all available
horizontal space. Especially useful for equal-width, or justified, navigation.
<div class="flex-fill">Flex item</div>
Responsive variations also exist for
flex-fill.
-
.flex-fill -
.flex-sm-fill -
.flex-md-fill -
.flex-lg-fill -
.flex-xl-fill
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.
<div class="flex-grow-1">Flex item</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.
<div class="w-100">Flex item</div>
<div class="flex-shrink-1">Flex item</div>
Responsive variations also exist for
flex-grow and
flex-shrink.
-
.flex-{grow|shrink}-0 -
.flex-{grow|shrink}-1 -
.flex-sm-{grow|shrink}-0 -
.flex-sm-{grow|shrink}-1 -
.flex-md-{grow|shrink}-0 -
.flex-md-{grow|shrink}-1 -
.flex-lg-{grow|shrink}-0 -
.flex-lg-{grow|shrink}-1 -
.flex-xl-{grow|shrink}-0 -
.flex-xl-{grow|shrink}-1
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 (
.mr-auto), and pushing two items to the left (
.ml-auto).
Unfortunately, IE10 and IE11 do not properly support auto margins on flex items whose parent has a non-default
justify-content value.
See this StackOverflow answer for more details.
<div class="d-flex mb-3">
<div class="p-2">Flex item</div>
<div class="p-2">Flex item</div>
<div class="p-2">Flex item</div>
</div>
<div class="d-flex mb-3">
<div class="mr-auto p-2">Flex item</div>
<div class="p-2">Flex item</div>
<div class="p-2">Flex item</div>
</div>
<div class="d-flex mb-3">
<div class="p-2">Flex item</div>
<div class="p-2">Flex item</div>
<div class="ml-auto p-2">Flex item</div>
</div>
With align-items
Similarly, move one flex item to the top or bottom of a container by mixing
align-items,
flex-direction: column, and
margin-top: auto or
margin-bottom: auto.
<div class="d-flex align-items-start flex-column" style="height: 200px;">
<div class="mb-auto p-2">Flex item</div>
<div class="p-2">Flex item</div>
<div class="p-2">Flex item</div>
</div>
<div class="d-flex align-items-end flex-column" style="height: 200px;">
<div class="p-2">Flex item</div>
<div class="p-2">Flex item</div>
<div class="mt-auto p-2">Flex item</div>
</div>
Wrap
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.
<div class="d-flex flex-nowrap">...</div>
<div class="d-flex flex-wrap">...</div>
<div class="d-flex flex-wrap-reverse">...</div>
Responsive variations also exist for
flex-wrap.

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.
<div class="d-flex flex-nowrap example-parent">
<div class="order-3 p-2 col-example">First flex item</div>
<div class="order-2 p-2 col-example">Second flex item</div>
<div class="order-1 p-2 col-example">Third flex item</div>
</div>

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.
Align content-start
<div class="d-flex align-content-start flex-wrap">...</div>
Align content-end
<div class="d-flex align-content-end flex-wrap">...</div>
Align content-center
<div class="d-flex align-content-center flex-wrap">...</div>
Align content-between
<div class="d-flex align-content-between flex-wrap">...</div>
Align content-around
<div class="d-flex align-content-around flex-wrap">...</div>
Align content-stretch
<div class="d-flex align-content-around flex-wrap">...</div>
