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 donΚΌt include explicit opacity information, the opacity is treated as 1.
Note: As a presentation attribute, stop-opacity can be used as a CSS property.
As a presentation attribute, it can be applied to any element but it has effect only on the following element: <stop>
