Font Weight

Usage

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

Responsive

To control the font weight of an element at a specific breakpoint, add a {screen}: prefix to any existing font weight utility. 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 ...">The quick brown fox jumps over the lazy dog.</p>

Customizing

Font Weights

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

  // tailwind.config.js
  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,
      }
    }
  }

Variants

By default, only responsive variants are generated for font weight utilities.

You can control which variants are generated for the font weight utilities by modifying the fontWeight property in the variants section of your tailwind.config.js file.

For example, this config will also generate hover and focus variants:

  // tailwind.config.js
  module.exports = {
    variants: {
      extend: {
        // ...
+       fontWeight: ['hover', 'focus'],
      }
    }
  }

Disabling

If you don't plan to use the font weight utilities in your project, you can disable them entirely by setting the fontWeight property to false in the corePlugins section of your config file:

  // tailwind.config.js
  module.exports = {
    corePlugins: {
      // ...
+     fontWeight: false,
    }
  }
