grayscale() - CSS | MDN
grayscale() Baseline Widely available
The grayscale()
CSS function converts the input image to grayscale. Its result is a <filter-function>
.
<section id="default-example">
<img
class="transition-all"
id="example-element"
src="/shared-assets/images/examples/firefox-logo.svg"
width="200" />
</section>
amount
Optional
Amount of the input image that is converted to grayscale. It is specified as a <number>
or a <percentage>
. A value of 100%
changes the input completely to grayscale, while a value of 0%
leaves the input unchanged. Values between 0%
and 100%
have linear multipliers on the effect. The initial value used for interpolation is 0
. The default value is 1
.
grayscale(0) /* No effect */
grayscale(.7) /* 70% grayscale */
grayscale() /* Completely grayscale */
grayscale(1)
grayscale(100%)
