Understanding align-items in Flexbox
The align-items property in Flexbox controls the alignment of flex items along the cross axis of a flex container. While justify-content manages spacing along the main axis, align-items ensures proper vertical or horizontal alignment depending on the flex direction.
align-itemsaligns all flex items along the cross axis (perpendicular to the main axis).Common values include:
flex-start: items are aligned at the start of the cross axis.flex-end: items are aligned at the end of the cross axis.center: items are centered along the cross axis.stretch(default): items stretch to fill the container along the cross axis.baseline: items align along their text baseline.
align-itemsaffects all items in the container, whilealign-selfcan override it for individual items.Useful for controlling vertical alignment in a row or horizontal alignment in a column layout.
In this example, align-items: center vertically centers all .item elements along the cross axis, while justify-content: space-around spaces them evenly along the main axis.
