The align-self property is a sub-property of the Flexible Box Layout module.

It makes possible to override the align-items value for specific flex items.

The align-self property accepts the same 5 values as the align-items:

• flex-start: cross-start margin edge of the item is placed on the cross-start line
• flex-end: cross-end margin edge of the item is placed on the cross-end line
• center: item is centered in the cross-axis
• baseline: items are aligned such as their baseline are aligned
• stretch (default): stretch to fill the container (still respect min-width/max-width)

Syntax

align-self: auto | flex-start | flex-end | center | baseline | stretch

.flex-item {
  align-self: flex-end;
}
