mask

The mask CSS shorthand property hides an element (partially or fully) by masking or clipping a specified area of the image. It is a shorthand for all the mask-* properties. The property accepts one or more comma-separated values, where each value corresponds to a <mask-layer>.

The mask shorthand property hides part or all of the element it is applied to. The parts of the element that are hidden, visible, or partially shown depend on either the opacity (alpha channel of the mask) or the brightness (luminance) of the mask. In alpha masking, opaque areas of the mask reveal the element, and transparent areas hide it. In luminance masking, light opaque areas of the mask reveal the element, and dark or transparent areas hide it.

Syntax example: mask: none;
