Basic usage

Controlling opacity of backdrop filters

Use the backdrop-opacity-{amount} utilities to control the opacity of other backdrop filters applied to an element.

Backdrop Opacity - 图1

  1. <div class="backdrop-opacity-10 backdrop-invert bg-white/30 ...">
  2. <!-- ... -->
  3. </div>
  4. <div class="backdrop-opacity-60 backdrop-invert bg-white/30 ...">
  5. <!-- ... -->
  6. </div>
  7. <div class="backdrop-opacity-95 backdrop-invert 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-opacity-60 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-opacity-60 to only apply the backdrop-opacity-60 utility on hover.

  1. <div class="backdrop-opacity-100 hover:backdrop-opacity-60">
  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-opacity-60 to apply the backdrop-opacity-60 utility at only medium screen sizes and above.

  1. <div class="backdrop-opacity-100 md:backdrop-opacity-60">
  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-opacity utilities. You can customize these values by editing theme.backdropOpacity or theme.extend.backdropOpacity in your tailwind.config.js file.

tailwind.config.js

  1. module.exports = { theme: { extend: { backdropOpacity: { 15: '.15', } } }}

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

Arbitrary values

If you need to use a one-off backdrop-opacity 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-opacity-[.15]">
  2. <!-- ... -->
  3. </div>

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