Backdrop Grayscale

Utilities for applying backdrop grayscale filters to an element.

Quick reference

Basic usage

Making an element grayscale

Use the backdrop-grayscale and backdrop-grayscale-0 utilities to control whether an element’s backdrop should be rendered as grayscale or in full color.

1. <div class="backdrop-grayscale-0 bg-white/30 ...">
2. <!-- ... -->
3. </div>
4. <div class="backdrop-grayscale bg-white/30 ...">
5. <!-- ... -->
6. </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-grayscale 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-grayscale-0 to only apply the backdrop-grayscale-0 utility on hover.

1. <div class="backdrop-grayscale hover:backdrop-grayscale-0">
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-grayscale-0 to apply the backdrop-grayscale-0 utility at only medium screen sizes and above.

1. <div class="backdrop-grayscale md:backdrop-grayscale-0">
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-grayscale utilities. You can customize these values by editing theme.backdropGrayscale or theme.extend.backdropGrayscale in your tailwind.config.js file.

tailwind.config.js

1. module.exports = {
2. theme: {
3. extend: {
4. backdropGrayscale: {
5. 50: '.5',
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-grayscale 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-grayscale-[.5]">
2. <!-- ... -->
3. </div>

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