Utilities for applying backdrop grayscale filters to an element.

Source: https://tailwindcss.com/guide/backdrop-filter-grayscale

Quick reference

• backdrop-grayscale, backdrop-grayscale-0, backdrop-grayscale-[<value>], backdrop-grayscale-(<custom-property>)

Examples

Basic example

Use utilities like backdrop-grayscale and backdrop-grayscale-0 to control the grayscale of an element's backdrop:

<div class="bg-[url(/img/mountains.jpg)]">
  <div class="bg-white/30 backdrop-grayscale ..."></div>
</div>
<div class="bg-[url(/img/mountains.jpg)]">
  <div class="bg-white/30 backdrop-grayscale-0 ..."></div>
</div>

Using a custom value

Use the backdrop-grayscale-[<value>] syntax to set the backdrop grayscale based on a completely custom value:

<div class="backdrop-grayscale-[.8] ...">
  <!-- ... -->
</div>

For CSS variables, you can also use the backdrop-grayscale-(<custom-property>) syntax:

<div class="backdrop-grayscale-(--my-backdrop-grayscale) ...">
  <!-- ... -->
</div>

This is just a shorthand for backdrop-grayscale-[var(<custom-property>)] that adds the var() function for you automatically.

Responsive design

Prefix a backdrop-filter: grayscale() utility with a breakpoint variant like md: to only apply the utility at medium screen sizes and above:

<div class="backdrop-grayscale md:backdrop-grayscale-0 ...">
  <!-- ... -->
</div>
