stop-opacity

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:
