+Change the alignment of elements with the [`vertical-alignment`](https://developer.mozilla.org/en-US/docs/Web/CSS/vertical-align) utilities. Please note that vertical-align only affects inline, inline-block, inline-table, and table cell elements.
+
+Choose from  `.align-baseline`, `.align-top`, `.align-middle`, `.align-bottom`, `.align-text-bottom`, and `.align-text-top` as needed.
+
+With inline elements:
+
+{% example html %}
+<span class="align-baseline">baseline</span>
+<span class="align-top">top</span>
+<span class="align-middle">middle</span>
+<span class="align-bottom">bottom</span>
+<span class="align-text-top">text-top</span>
+<span class="align-text-bottom">text-bottom</span>
+{% endexample %}
+
+With table cells:
+
+{% example html %}
+<table style="height: 100px;">
+  <tbody>
+    <tr>
+      <td class="align-baseline">baseline</td>
+      <td class="align-top">top</td>
+      <td class="align-middle">middle</td>
+      <td class="align-bottom">bottom</td>
+      <td class="align-text-top">text-top</td>
+      <td class="align-text-bottom">text-bottom</td>
+    </tr>
+  </tbody>
+</table>
+{% endexample %}
