- The brightness of the result, specified as 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
brightness(0%) /* Completely black */ brightness(0.4) /* 40% brightness */ brightness(1) /* No effect */ brightness(200%) /* Double brightness */
