Flex

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.

<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

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>
<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.

  • .flex-row
  • .flex-column
  • .flex-row-reverse
  • .flex-column-reverse
  • .flex-sm-row

  • .flex-sm-column-reverse
  • .flex-md-row
  • .flex-md-column
  • .flex-md-row-reverse
  • .flex-md-column-reverse

  • .flex-lg-column-reverse
  • .flex-xl-row
  • .flex-xl-column

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-wrap"></div>
<div class="d-flex flex-nowrap"></div>
<div class="d-flex flex-wrap-reverse"></div>

Shrink and grow

Use .flex-shrink-* 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.

  • .flex-{shrink|grow}-0
  • .flex-{shrink|grow}-1

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.

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

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

<div class="d-flex align-items-start"></div>
<div class="d-flex align-items-end"></div>

<div class="d-flex align-self-auto"></div>

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.

<div class="d-flex">
  <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>
  • .order-0
  • .order-1
  • .order-2
  • .order-3
  • .order-4
  • .order-5
  • .order-sm-0
  • .order-sm-1
  • .order-sm-2

Additionally there are also responsive .order-first and .order-last classes that change the order of an element by applying order: -1 and order: 6, respectively.

  • .order-first
  • .order-last
  • .order-sm-first
  • .order-sm-last
  • .order-md-first
