The grayscale()
CSS function converts the input image to grayscale. Its result is a <filter-function>
.
grayscale(amount)
amount
<number>
or a <percentage>
. A value of 100%
is completely grayscale, while a value of 0%
leaves the input unchanged. Values between 0%
and 100%
are linear multipliers on the effect. The lacuna value for interpolation is 0
.grayscale(0) /* No effect */ grayscale(.7) /* 70% grayscale */ grayscale(100%) /* Completely grayscale */
