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 September 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 also has a CSS property counterpart: stop-opacity. When both are specified, the CSS property takes priority.
You can use this attribute with the following SVG elements:
