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.

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.

Use .flex-column to set a vertical direction, or .flex-column-reverse to start the vertical direction from the opposite side.

Justify

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 flex-start (browser default), flex-end, center, space-between, space-around, or space-evenly.

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).

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).

Grow and Shrink

Use .flex-grow-{0-1} 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.

Third flex item

Use .flex-shrink-{0-1} 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, “shrinking” to allow more space for the previous flex item with .w-100.

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 12, 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 flex-start (browser default), flex-end, center, space-between, space-around, or stretch. To demonstrate these utilities, we’ve enforced flex-wrap: wrap and increased the number of flex items.
