backdrop-grayscale

backdrop-grayscale

Sets backdrop-grayscale via --backdrop-grayscale.

CSS Rules

.backdrop-grayscale {
  backdrop-filter: grayscale(var(--backdrop-grayscale));
}

Usage

<element class="backdrop-grayscale" style="--backdrop-grayscale: /* value */;" />

Responsive

Prefix .backdrop-grayscale utility with a breakpoint variant (e.g., md:) to apply styles at specific screen sizes (Supported breakpoints are xm through 2xl).

<element class="md:backdrop-grayscale" style="--md-backdrop-grayscale: /* value */;" />

States

States are generated dynamically at runtime and always come last. Append a state like :hover or :focus to the end of the class. This works in conjunction with breakpoints .

Supported pseudo-classes: :hover, :active, :focus, :focus-visible, :focus-within, :target, :checked, :disabled, and :group-hover.

<element class="backdrop-grayscale:hover" style="--backdrop-grayscale-hover: /* value */;" />

Group Hover Example

The :group-hover state applies styles when a parent element with the .group class is hovered.

<element class="group">
  <element class="backdrop-grayscale:group-hover">...</element>
</element>

Pseudo-Elements

The ::before and ::after utility classes are supported too. Granted that you add the mandatory content-before or content-after class in order for them to work.

<element class="content-before backdrop-grayscale::before" style="--backdrop-grayscale-before: /* value */;" />

<element class="content-after backdrop-grayscale::after" style="--backdrop-grayscale-after: /* value */;" />

Shorthand

Value-driven classes support a shorthand syntax like bg=pink or p=4. The runtime processes this for you. Unlike :hover that is generating CSS on the fly, shorthand only splits it and appends the corresponding style.

<!-- Input -->
<element class="backdrop-grayscale=value" />

<!-- Output -->
