Default class reference

Class
Properties
backdrop-blur-none--tw-backdrop-blur: blur(0);
backdrop-blur-sm--tw-backdrop-blur: blur(4px);
backdrop-blur--tw-backdrop-blur: blur(8px);
backdrop-blur-md--tw-backdrop-blur: blur(12px);
backdrop-blur-lg--tw-backdrop-blur: blur(16px);
backdrop-blur-xl--tw-backdrop-blur: blur(24px);
backdrop-blur-2xl--tw-backdrop-blur: blur(40px);
backdrop-blur-3xl--tw-backdrop-blur: blur(64px);

Usage

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

<div class="backdrop-filter backdrop-blur-lg ...">
  <!-- ... -->
</div>

Responsive

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

<div class="backdrop-filter backdrop-blur-sm md:backdrop-blur-lg ...">
  <!-- ... -->
</div>

Customizing

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

  // tailwind.config.js
  module.exports = {
    theme: {
+     extend: {
+       backdropBlur: {
+         xs: '2px',
+       }
+     }
    }
  }

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

Variants

By default, only responsive variants are generated for backdrop blur utilities.

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

Disabling

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

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