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.

Setting contrast using numbers and percentages

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

The problem with hoarding is you end up living off your reserves. Eventually, you’ll become stale. If you give away everything you have, you are left with nothing. This forces you to look, to be aware, to replenish. . . . Somehow the more you give away, the more comes back to you.
