Quick reference

Basic usage

Setting the font weight

Control the font weight of an element using the font-{weight} utilities.

<p class="font-light ...">The quick brown fox ...</p>
<p class="font-normal ...">The quick brown fox ...</p>
<p class="font-medium ...">The quick brown fox ...</p>
<p class="font-semibold ...">The quick brown fox ...</p>
<p class="font-bold ...">The quick brown fox ...</p>

Applying conditionally

Hover, focus, and other states

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

<p class="font-normal hover:font-bold">
  <!-- ... -->
</p>

For a complete list of all available state modifiers, check out the Hover, Focus, & Other States documentation.

Breakpoints and media queries

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

<p class="font-normal md:font-bold">
  <!-- ... -->
</p>

To learn more, check out the documentation on Responsive Design, Dark Mode and other media query modifiers.

Using custom values

Customizing your theme

By default, Tailwind provides nine font-weight utilities. You change, add, or remove these by editing the theme.fontWeight section of your Tailwind config.

module.exports = {
  theme: {
    fontWeight: {
      thin: '100',
      hairline: '100',
      extralight: '200',
      light: '300',
      normal: '400',
      medium: '500',
      semibold: '600',
      bold: '700',
      extrabold: '800',
      'extra-bold': '800',
      black: '900',
    }
  }
}

Learn more about customizing the default theme in the theme customization documentation.

Arbitrary values

If you need to use a one-off font-weight 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.

<p class="font-[1100]">
  <!-- ... -->
</p>

Learn more about arbitrary value support in the arbitrary values documentation.
