Basic usage

Blurring behind an element

Use the backdrop-blur-* utilities to control an element’s backdrop blur.




<div class="backdrop-blur-sm bg-white/30 ...">
  <!-- ... -->
<div class="backdrop-blur-md bg-white/30 ...">
  <!-- ... -->
<div class="backdrop-blur-xl bg-white/30 ...">
  <!-- ... -->

Removing backdrop filters

To remove all of the backdrop filters on an element at once, use the backdrop-filter-none utility:

<div class="backdrop-blur-md backdrop-brightness-150 md:backdrop-filter-none">
  <!-- ... -->

This can be useful when you want to remove backdrop filters conditionally, such as on hover or at a particular breakpoint.

Applying conditionally

Hover, focus, and other states

Tailwind lets you conditionally apply utility classes in different states using variant modifiers. For example, use hover:backdrop-blur-lg to only apply the backdrop-blur-lg utility on hover.

<div class="backdrop-blur-sm hover:backdrop-blur-lg">
  <!-- ... -->

For a complete list of all available state modifiers, check out the Hover, Focus, & Other States documentation.

Breakpoints and media queries

You can also use variant modifiers to target media queries like responsive breakpoints, dark mode, prefers-reduced-motion, and more. For example, use md:backdrop-blur-lg to apply the backdrop-blur-lg utility at only medium screen sizes and above.

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

To learn more, check out the documentation on Responsive Design, Dark Mode and other media query modifiers.

Using custom values

Customizing your theme

By default, Tailwind includes a handful of general purpose backdrop-blur utilities. You can customize these values by editing theme.backdropBlur or theme.extend.backdropBlur in your tailwind.config.js file.

module.exports = {
  theme: {
    extend: {
      backdropBlur: {
        xs: '2px',

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

Arbitrary values

If you need to use a one-off backdrop-blur value that doesn’t make sense to include in your theme, use square brackets to generate a property on the fly using any arbitrary value.

<div class="backdrop-blur-[2px]">
  <!-- ... -->
