mask
Baseline 2023Newly available
Since December 2023, this feature works across the latest devices and browser versions. This feature might not work in older devices or browsers.
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
also has a CSS property counterpart: mask
. When both are specified, the CSS property takes priority.
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
.
