contrast()

The contrast() CSS function adjusts the contrast of the input image. Its result is a <filter-function>.

Syntax

contrast(amount)

Parameters

amount
The contrast of the result, specified as a <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.

Examples

contrast(0)     /* Completely gray */
contrast(65%)   /* 65% contrast */
contrast(1)     /* No effect */
contrast(200%)  /* Double contrast */
