+Set the `visibility` of elements with our visibility utilities. These utility classes do not modify the `display` value at all and do not affect layout – `.invisible` elements still take up space in the page.
+
+{{< callout warning >}}
+Elements with the `.invisible` class will be hidden *both* visually and for assistive technology/screen reader users.
+{{< /callout >}}
+
+Apply `.visible` or `.invisible` as needed.
