Definition and Usage

The align-items property specifies the default alignment for items inside a flexbox or grid container.

  • In a flexbox container, the flexbox items are aligned on the cross axis, which is vertical by default (opposite of flex-direction).
  • In a grid container, the grid items are aligned in the block direction. For pages in English, block direction is downward and inline direction is left to right.

For this property to have any alignment effect, the items need available space around themselves in the appropriate direction.

Tip: Use the align-self property of each item to override the align-items property.
