CSS - align-content Property

The align-content property of CSS is used to align the content of a flex container along the cross-axis or a grid's block axis. It applies to flex containers with multiple lines of flex items.

The property align-content has no effect on single line flex containers (flex-wrap: nowrap).

Possible Values

The align-content property can have following values:

  • start: Items are aligned to each other against the start edge of the container in the cross-axis.

  • end: Items are aligned to each other against the end edge of the container in the cross-axis.

  • flex-start: Aligns the content at the start of the flex container.

  • flex-end: Aligns the content at the end of the flex container.

  • center: Aligns the content at the center of the flex container.

  • normal: Items are aligned at their default position, as if no value is set for align-content.

  • baseline, first baseline, last baseline:

    • First baseline, and last baseline are synonym to baseline. First and last refer to the line boxes within the flex items.

    • These values specify the involvment of first- or last-baseline alignment in the alignment of the content.

    • start is the fallback alignment for first-baseline and end for last-baseline.

  • space-between: Distributes the content evenly along the cross-axis, leaving no space before the first line or after the last line.

  • space-around: Distributes the content evenly along the cross-axis, providing equal space before and after each line.

  • space-evenly: Distributes the content evenly along the cross-axis, providing equal space before, between, and after each line.

  • stretch: Stretches the content to fill the container along the cross-axis.

  • safe: Used with an alignment keyword and when the item overflows the container, causing any loss of data, the alignment is set as per the start value.

  • unsafe: Used with an alignment keyword and even if the item overflows the container, causing any loss of data, the alignment value passed is honored.

Applies to

Multi-line flex containers.
