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:
| 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.
