The contrast()
CSS function adjusts the contrast of the input image. Its result is a <filter-function>
.
contrast(amount)
amount
<number>
or a <percentage>
. A value under 100%
decreases the contrast, while a value over 100%
increases it. A value of 0%
will create an image that is completely gray, while a value of 100%
leaves the input unchanged. The lacuna value for interpolation is 1
.contrast(0) /* Completely gray */ contrast(65%) /* 65% contrast */ contrast(1) /* No effect */ contrast(200%) /* Double contrast */
