Examples

Basic example

Use utilities like backdrop-blur-sm and backdrop-blur-lg to control an element’s backdrop blur:

        <div className="absolute inset-0 rounded-lg ring-1 ring-black/10 ring-inset"></div>
      </div>
    </div>
    <div className="flex shrink-0 flex-col items-center">
      <p className="mb-3 text-center font-mono text-xs font-medium text-gray-500 dark:text-gray-400">
        backdrop-blur-sm
      </p>
      <div className="relative">
        <div className="absolute inset-6 size-20 bg-white/30 backdrop-blur-sm"></div>
        
        <div className="absolute inset-0 rounded-lg ring-1 ring-black/10 ring-inset"></div>
      </div>
    </div>
    <div className="flex shrink-0 flex-col items-center">
      <p className="mb-3 text-center font-mono text-xs font-medium text-gray-500 dark:text-gray-400">
        backdrop-blur-md
      </p>
      <div className="relative">
        <div className="absolute inset-6 size-20 bg-white/30 backdrop-blur-md"></div>
        
        <div className="absolute inset-0 rounded-lg ring-1 ring-black/10 ring-inset"></div>
      </div>
    </div>
  </div>
</div>

} </Example>

<!-- [!code classes:backdrop-blur-none,backdrop-blur-sm,backdrop-blur-md] -->
<div class="bg-[url(/img/mountains.jpg)]">
  <div class="bg-white/30 backdrop-blur-none ..."></div>
</div>
<div class="bg-[url(/img/mountains.jpg)]">
  <div class="bg-white/30 backdrop-blur-sm ..."></div>
</div>
<div class="bg-[url(/img/mountains.jpg)]">
  <div class="bg-white/30 backdrop-blur-md ..."></div>
</div>
