Basic usage

Controlling backdrop brightness

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

backdrop-brightness-50

backdrop-brightness-125

backdrop-brightness-200

<div class="backdrop-brightness-50 bg-white/30 ...">
  <!-- ... -->
</div>
<div class="backdrop-brightness-125 bg-white/30 ...">
  <!-- ... -->
</div>
<div class="backdrop-brightness-200 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-brightness-150 to only apply the backdrop-brightness-150 utility on hover.

<div class="backdrop-brightness-110 hover:backdrop-brightness-150">
  <!-- ... -->
</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-brightness-150 to apply the backdrop-brightness-150 utility at only medium screen sizes and above.

<div class="backdrop-brightness-110 md:backdrop-brightness-150">
  <!-- ... -->
</div>

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-brightness utilities. You can customize these values by editing theme.backdropBrightness or theme.extend.backdropBrightness in your tailwind.config.js file.

tailwind.config.js

module.exports = {
  theme: {
    extend: {
      backdropBrightness: {
        25: '.25',
        175: '1.75',
      }
    }
  }
}

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

Arbitrary values

If you need to use a one-off backdrop-brightness 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-brightness-[1.75]">
  <!-- ... -->
</div>
