Abstract: CSS Masking provides two means for partially or fully hiding portions of visual elements: masking and clipping.
Abstract: 
Abstract: Masking describes how to use another graphical element or image as a luminance or alpha mask. Typically, rendering an element via CSS or SVG can conceptually described as if the element, including its children, are drawn into a buffer and then that buffer is composited into the element's parent. Luminance and alpha masks influence the transparency of this buffer before the compositing stage.

Abstract: Clipping describes the visible region of visual elements. The region can be described by using certain SVG graphics elements or basic shapes. Anything outside of this region is not rendered.
