How can I blur the background of an element (glassmorphism) in Tailwind CSS?

Asked on Sep 12, 2025

Answer

To achieve a glassmorphism effect in Tailwind CSS, you can use the backdrop-blur utility to blur the background of an element. This utility applies a blur effect to the area behind the element, creating a frosted glass appearance.
<!-- BEGIN COPY / PASTE -->
    <div class="bg-white bg-opacity-30 backdrop-blur-md p-6 rounded-lg">
      <p class="text-white">This is a glassmorphism effect.</p>
    </div>
    <!-- END COPY / PASTE -->
Additional Comment:
  • Use "bg-opacity-30" to make the background semi-transparent, enhancing the glass effect.
  • "backdrop-blur-md" applies a medium level of blur to the backdrop.
  • Adjust the blur intensity with classes like "backdrop-blur-sm" or "backdrop-blur-lg" for different effects.
  • Ensure the parent element has a background image or color to see the blur effect.
