Font Weight 粗细

​

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

module.exports = {  theme: {    fontWeight: {      hairline: 100,      'extra-light': 100,      thin: 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.
