Brightness

Usage

Use the brightness-{amount?} utilities alongside the filter utility to control an element’s brightness.

<div class="filter brightness-125 ...">
  <!-- ... -->
</div>

Responsive

To control an element’s brightness at a specific breakpoint, add a {screen}: prefix to any existing brightness utility. For example, use md:brightness-150 to apply the brightness-150 utility at only medium screen sizes and above.

<div class="filter brightness-110 md:brightness-150 ...">
  <!-- ... -->
</div>

Customizing

You can customize which brightness utilities are generated using the brightness key in the theme section of your tailwind.config.js file.

  // tailwind.config.js
  module.exports = {
    theme: {
+     extend: {
+       brightness: {
+         25: '.25',
+         175: '1.75',
+       }
+     }
    }
  }

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

Variants

By default, only responsive variants are generated for brightness utilities.

You can control which variants are generated for the brightness utilities by modifying the brightness 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: {
        // ...
+       brightness: ['hover', 'focus'],
      }
    }
  }

Disabling

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

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