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.
