Basic example

Use utilities like backdrop-brightness-50 and backdrop-brightness-100 to control an element's backdrop brightness:

<Figure> <Example padding={false}> { <div className="flex scroll-p-8 justify-start overflow-scroll sm:block sm:overflow-visible"> <div className="flex shrink-0 items-center justify-around gap-6 p-8 font-mono font-bold sm:gap-4"> <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-brightness-50 </p> <div className="relative"> <div className="absolute inset-6 size-20 bg-white/30 backdrop-brightness-50"></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-brightness-150
      </p>
      <div className="relative">
        <div className="absolute inset-6 size-20 bg-white/30 backdrop-brightness-150"></div>
        
        <div className="absolute inset-0 rounded-lg ring-1 ring-black/10 ring-inset"></div>
      </div>
    </div>
  </div>
</div>
