Backdrop Blur

? Basic usage

? Blurring behind an element

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

backdrop-blur-sm

backdrop-blur-md

backdrop-blur-xl

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

  <!-- ... -->

</
div
>

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

  <!-- ... -->

</
div
>

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

  <!-- ... -->

</
div
>

? 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
"
>

  <!-- ... -->

</
div
>

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
"
>

  <!-- ... -->

</
div
>

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
"
>

  <!-- ... -->

</
div
>

? 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]
"
>

  <!-- ... -->

</
div
>
