fill-opacity
Baseline Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2020.
The fill-opacity
attribute is a presentation attribute defining the opacity of the paint server (color, gradient, pattern, etc.) applied to a shape.
Note:
As a presentation attribute fill-opacity
can be used as a CSS property.
You can use this attribute with the following SVG elements:
Example
html
<svg viewBox="0 0 400 100" xmlns="http://www.w3.org/2000/svg">
<!-- Default fill opacity: 1 -->
<circle cx="50" cy="50" r="40" />
<!-- Fill opacity as a number -->
<circle cx="150" cy="50" r="40" fill-opacity="0.7" />
<!-- Fill opacity as a percentage -->
<circle cx="250" cy="50" r="40" fill-opacity="50%" />
<!-- Fill opacity as a CSS property -->
<circle cx="350" cy="50" r="40" style="fill-opacity: .25;" />
</svg>

SVG2 introduces percentage values for fill-opacity
, however, it is not widely supported yet (See Browser compatibility below) as a consequence, it is best practices to set opacity with a value in the range [0-1]
