stop-opacity

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since January 2020.

The stop-opacity attribute defines the opacity of a given color gradient stop.

The opacity value used for the gradient calculation is the product of the value of stop-opacity and the opacity of the value of the stop-color attribute. For stop-color values that don't include explicit opacity information, the opacity is treated as 1.

Note: As a presentation attribute, stop-opacity can be used as a CSS property.

You can use this attribute with the following SVG elements:

Usage notes

Value <opacity-value>
Default value 1
Animatable Yes
<opacity-value>

This value is either a <number> between 0 and 1 or a <percentage> value specifying the opacity of the color gradient stop.
