Examples

Different alignment:

<style>
  .row { display: flex; gap: 6px; height: 80px; background: whitesmoke; margin-bottom: 6px; }
  .row div { padding: 6px; background: plum; }
</style>
 
<div class="row"><div>stretch</div><div>default</div></div>
<div class="row" style="align-items: center;"><div>center</div><div>center</div></div>
<div class="row" style="align-items: flex-end;"><div>end</div><div>end</div></div>

Centering in both directions:

<div style="display: flex; align-items: center; justify-content: center; height: 100px; background: honeydew;">
  Exactly in the center
</div>

Notes

In a column (flex-direction: column) align-items works horizontally. For a single item, use align-self.
