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 bg-200 mb-2">Flexbox container!</div>
<div class="d-inline-flex p-2 bg-200">Inline flexbox container!</div>

Direction Row

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 bg-200 mb-3 flex-row">
  <div class="p-2 bg-200 border border-400">Flex item 1</div>
  <div class="p-2 bg-200 border border-400">Flex item 2</div>
  <div class="p-2 bg-200 border border-400">Flex item 3</div>
</div>
<div class="d-flex bg-200 mb-3 flex-row-reverse">
  <div class="p-2 bg-200 border border-400">Flex item 1</div>
  <div class="p-2 bg-200 border border-400">Flex item 2</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 bg-200 mb-3 flex-column">
  <div class="p-2 bg-200 border border-400">Flex item 1</div>
  <div class="p-2 bg-200 border border-400">Flex item 2</div>

Justify Content

justify-contentjustify-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 , oraround.

<div class="d-flex justify-content-start bg-200 mb-2">
  <div class="p-2 bg-200 border border-400">Flex Item</div>
</div>
<div class="d-flex justify-content-end bg-200 mb-2">
  <div class="p-2 bg-200 border border-400">Flex Item</div>
</div>
<div class="d-flex justify-content-center bg-200 mb-2">
  <div class="p-2 bg-200 border border-400">Flex Item</div>
</div>
<div class="d-flex justify-content-between bg-200 mb-2">
  <div class="p-2 bg-200 border border-400">Flex Item</div>
</div>
<div class="d-flex justify-content-around bg-200 mb-2">
  <div class="p-2 bg-200 border border-400">Flex Item</div>
</div>

Flex Item

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 bg-200 mb-2" style="height: 5rem;">
  <div class="p-2 bg-200 border border-400">Flex item</div>
</div>
<div class="d-flex align-items-end bg-200 mb-2" style="height: 5rem;">
  <div class="p-2 bg-200 border border-400">Flex item</div>
</div>
<div class="d-flex align-items-center bg-200 mb-2" style="height: 5rem;">
  <div class="p-2 bg-200 border border-400">Flex item</div>
</div>
<div class="d-flex align-items-baseline bg-200 mb-2" style="height: 5rem;">
  <div class="p-2 bg-200 border border-400">Flex item</div>
</div>
<div class="d-flex align-items-stretch bg-200 mb-2" style="height: 5rem;">
  <div class="p-2 bg-200 border border-400">Flex item</div>
</div>

Flex item

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="d-flex bg-200 mb-2" style="height: 5rem;">
  <div class="border border-400 p-2 bg-200">Flex Item</div>
  <div class="border border-400 p-2 bg-200 align-self-start">Align self start</div>
  <div class="border border-400 p-2 bg-200">Flex Item</div>
</div>
<div class="d-flex bg-200 mb-2" style="height: 5rem;">
  <div class="border border-400 p-2 bg-200">Flex Item</div>
  <div class="border border-400 p-2 bg-200 align-self-end">Align self end</div>
  <div class="border border-400 p-2 bg-200">Flex Item</div>
</div>
<div class="d-flex bg-200 mb-2" style="height: 5rem;">
  <div class="border border-400 p-2 bg-200">Flex Item</div>
  <div class="border border-400 p-2 bg-200 align-self-center">Align self center</div>
  <div class="border border-400 p-2 bg-200">Flex Item</div>
</div>
<div class="d-flex bg-200 mb-2" style="height: 5rem;">
  <div class="border border-400 p-2 bg-200">Flex Item</div>
  <div class="border border-400 p-2 bg-200 align-self-baseline">Align self baseline</div>
  <div class="border border-400 p-2 bg-200">Flex Item</div>

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.

<div class="d-flex bg-200">
  <div class="p-2 flex-fill bg-200 border border-400">Flex item with a lot of content</div>
  <div class="p-2 flex-fill bg-200 border border-400">Flex item</div>
  <div class="p-2 flex-fill bg-200 border border-400">Flex item</div>
</div>

Flex Grow

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="d-flex bg-200">
  <div class="p-2 flex-grow-1 bg-200 border border-400">Flex item</div>
  <div class="p-2 bg-200 border border-400">Flex item</div>
  <div class="p-2 bg-200 border border-400">Third flex item</div>
</div>

Third flex item

Flex Shrink

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="d-flex bg-200">
  <div class="p-2 w-100 bg-200 border border-400">Flex item</div>
  <div class="p-2 flex-shrink-1 bg-200 border border-400">Flex item</div>
</div>

Flex item

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 ).

<div class="d-flex bg-200 mb-2">
  <div class="p-2 bg-200 border border-400">Flex item</div>
  <div class="p-2 bg-200 border border-400">Flex item</div>
  <div class="p-2 bg-200 border border-400">Flex item</div>
</div>
<div class="d-flex bg-200 mb-2">
  <div class="me-auto p-2 bg-200 border border-400">Flex item</div>
  <div class="p-2 bg-200 border border-400">Flex item</div>
  <div class="p-2 bg-200 border border-400">Flex item</div>
</div>
<div class="d-flex bg-200 mb-2">
  <div class="p-2 bg-200 border border-400">Flex item</div>
  <div class="p-2 bg-200 border border-400">Flex item</div>
  <div class="ms-auto p-2 bg-200 border border-400">Flex item</div>
</div>

Flex item

Align items

Vertically 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 flex-column bg-200 mb-3 align-items-start" style="height: 200px;">
  <div class="mb-auto p-2 bg-200 border border-400">Flex item</div>
  <div class="p-2 bg-200 border border-400">Flex item</div>
  <div class="p-2 bg-200 border border-400">Flex item</div>
</div>
<div class="d-flex flex-column bg-200 mb-3 align-items-end" style="height: 200px;">
  <div class="mb-auto p-2 bg-200 border border-400">Flex item</div>
  <div class="p-2 bg-200 border border-400">Flex item</div>
  <div class="p-2 bg-200 border border-400">Flex item</div>
</div>

Flex item

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 mb-3 bg-200 border border-300 py-3" style="width: 8rem">
  <div class="p-2 bg-200 border border-400">Flex item</div>

Order

Change the visualorder 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 bg-200">
  <div class="order-3 p-2 bg-200 border border-400">First flex item</div>
  <div class="order-2 p-2 bg-200 border border-400">Second flex item</div>
  <div class="order-1 p-2 bg-200 border border-400">Third flex item</div>
</div>

Aligh content

Use align-content utilities on flexbox containers to align flex itemstogetheron 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.

<div class="d-flex flex-wrap bg-200 mb-3 align-content-start" style="height: 300px;">
  <div class="p-2 bg-200 border border-400">Flex item</div>
