The additive attribute controls whether or not an animation is additive.
It is frequently useful to define animation as an offset or delta to an attribute's value, rather than as absolute values.
Four elements are using this attribute: <animate>, <animateColor>, <animateMotion>, and <animateTransform>
Usage notes
| Value | replace | sum |
|---|---|
| Default value | replace |
| Animatable | No |
- sum
- Specifies that the animation will add to the underlying value of the attribute and other lower priority animations.
- replace
- Specifies that the animation will override the underlying value of the attribute and other lower priority animations. This is the default, however the behavior is also affected by the animation value attributes
byandto, as described in SMIL Animation: How from, to and by attributes affect additive behavior.
