Height

Utilities for setting the height of an element.

Show all classes

Use or h-px to set an element to a fixed height.

Full height

Use h-full to set an element’s height to 100% of its parent, as long as the parent has a defined height.

<div class="h-48">
  <div class="h-full ...">
    <!-- This element will have a height of `12rem` (h-48) -->
  </div>
</div>

Hover, focus, and other states

Tailwind lets you conditionally apply utility classes in different states using variant modifiers. For example, use hover:h-full to only apply the h-full utility on hover.

  <!-- ... -->
</div>

For a complete list of all available state modifiers, check out the documentation.

You can also use variant modifiers to target media queries like responsive breakpoints, dark mode, prefers-reduced-motion, and more. For example, use md:h-full to apply the h-full utility at only medium screen sizes and above.

To learn more, check out the documentation on , Dark Mode and .

Customizing your theme

By default, Tailwind’s height scale is a combination of the default spacing scale as well as some additional values specific to heights.

tailwind.config.js

  theme: {
    extend: {
        '128': '32rem',
      }
    }
  }
}

To customize height separately, use the theme.height section of your tailwind.config.js file.

tailwind.config.js

Learn more about customizing the default theme in the documentation.

If you need to use a one-off height value that doesn’t make sense to include in your theme, use square brackets to generate a property on the fly using any arbitrary value.

<div class="h-[32rem]">
