Flexbox: Vertical and horizontal alignment

By default items start from the left if flex-direction is row, and from the top if flex-direction is column.

Vertical and horizontal alignment

You can change this behavior using justify-content to change the horizontal alignment, and align-items to change the vertical alignment.

Change the horizontal alignment

justify-content has 5 possible values:

  • flex-start: align to the left side of the container.
  • flex-end: align to the right side of the container.
  • center: align at the center of the container.
  • space-between: display with equal spacing between them.
  • space-around: display with equal spacing around them

Horizontal alignment

Change the vertical alignment

align-items has 5 possible values:

  • flex-start: align to the top of the container.
  • flex-end: align to the bottom of the container.
  • center: align at the vertical center of the container.
  • baseline: display at the baseline of the container.
  • stretch: items are stretched to fit the container.

Vertical alignment

A note on baseline

baseline looks similar to flex-start in this example, due to my boxes being too simple. Check out this Codepen to have a more useful example, which I forked from a Pen originally created by Martin Michálek. As you can see there, items dimensions are aligned.
