CSS align-items Property

The align-items property defines how the browser distributes space between and around flex items along the cross-axis (vertically) of their flex container. This means it works like justify-content but in the perpendicular direction.

CSS Demo: align-items

align-items: stretch;
align-items: flex-start;
align-items: center;
align-items: flex-end;

2
3

The difference to the align-content property is that align-items specifies the alignment of the items within the current flex container's line, whereas align-content specifies the alignment of the lines themselves.

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