CSS align-self property is used to align the selected item inside current flex line and override align-items value.

CSS align-self property will be ignored, if any of flex item's vertical margin is set to auto.

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

  • stretch
  • flex-start
  • center
  • flex-end
  • baseline

CSS Syntax

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

Let's see an example:

<!DOCTYPE html>
      #example {
        width: 220px;
        height: 300px;
        padding: 0;
        border: 1px solid black;
        display: -webkit-flex; /* Safari */
        -webkit-align-items: flex-start; /* Safari 7.0+ */
        display: flex;
        align-items: flex-end;
      #example li {
        -webkit-flex: 1; /* Safari 6.1+ */
        flex: 1;
        list-style: none;
      #blue {
        -webkit-align-self: center; /* Safari 7.0+ */
        align-self: flex-start;
    <ul id="example">
      <li style="background-color:#8ebf42;">GREEN</li>
      <li style="background-color:#1c87c9;" id="blue">BLUE</li>
      <li style="background-color:yellow;">We can place more content in Yellow area</li>

Here the result is:
