Basic usage

Changing backdrop saturation

Use the backdrop-saturate-{amount} utilities to control an element’s backdrop saturation.

Backdrop Saturate - 图1

  1. <div class="backdrop-saturate-50 bg-white/30 ...">
  2. <!-- ... -->
  3. </div>
  4. <div class="backdrop-saturate-125 bg-white/30 ...">
  5. <!-- ... -->
  6. </div>
  7. <div class="backdrop-saturate-200 bg-white/30 ...">
  8. <!-- ... -->
  9. </div>

Removing backdrop filters

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

  1. <div class="backdrop-blur-md backdrop-saturate-150 md:backdrop-filter-none">
  2. <!-- ... -->
  3. </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-saturate-150 to only apply the backdrop-saturate-150 utility on hover.

  1. <div class="backdrop-saturate-50 hover:backdrop-saturate-150">
  2. <!-- ... -->
  3. </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-saturate-150 to apply the backdrop-saturate-150 utility at only medium screen sizes and above.

  1. <div class="backdrop-saturate-50 md:backdrop-saturate-150">
  2. <!-- ... -->
  3. </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-saturate utilities. You can customize these values by editing theme.backdropSaturate or theme.extend.backdropSaturate in your tailwind.config.js file.

tailwind.config.js

  1. module.exports = {
  2. theme: {
  3. extend: {
  4. backdropSaturate: {
  5. 25: '.25',
  6. }
  7. }
  8. }
  9. }

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

Arbitrary values

If you need to use a one-off backdrop-saturate 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.

  1. <div class="backdrop-saturate-[.25]">
  2. <!-- ... -->
  3. </div>

Learn more about arbitrary value support in the arbitrary values documentation.
