The brightness()
CSS function applies a linear multiplier to the input image, making it appear brighter or darker. Its result is a <filter-function>
.
brightness(amount)
amount
<number>
or a <percentage>
. A value under 100%
darkens the image, while a value over 100%
brightens it. A value of 0%
will create an image that is completely black, while a value of 100%
leaves the input unchanged. The lacuna value for interpolation is 1
.brightness(0%) /* Completely black */ brightness(0.4) /* 40% brightness */ brightness(1) /* No effect */ brightness(200%) /* Double brightness */
