The mask
attribute is a presentation attribute mainly used to bind a given <mask>
element with the element the attribute belongs to.
Note: As a presentation attribute mask
can be used as a CSS property.
You can use this attribute with the following SVG elements:
Example
<svg viewBox="0 0 200 100" xmlns="http://www.w3.org/2000/svg">
<mask id="myMask" maskContentUnits="objectBoundingBox">
<rect fill="white" x="0" y="0" width="100%" height="100%" />
<polygon fill="black" points="0.5,0.2 0.68,0.74 0.21,0.41 0.79,0.41 0.32,0.74" />
</mask>
<!--
Punch a hole in a shape of a star inside the red circle,
revealing the yellow circle underneath
-->
<circle cx="50" cy="50" r="20" fill="yellow" />
<circle cx="50" cy="50" r="45" fill="red"
mask="url(#myMask)"/>
</svg>
Since SVG2, the mask
attribute is defined as a css property and is a shorthand for many other properties: mask-image
, mask-mode
, mask-repeat
, mask-position
, mask-clip
, mask-origin
, mask-size
, and mask-composite
.
