Shall WebAnimation also animate HTML attributes at some point?

I don't know. We've talked in the past about animating class. I'd also like to be able to animate scroll offsets at some point.

If yes, shall these attributes be “html” prefixed as well?

Yes. I think that would make sense.

What happens with the “svg*” attribute animation once we promoted the attribute to a CSS property/ presentation attribute?

* If the promotion matches the syntax and name, then animating either svgFoo or foo will produce identical results.
* If the promition matches the syntax, but the name foo becomes bar when promoted, then animating svgFoo and animating bar will produce identical results.
etc..

What about the CSS properties width/height and the width/height attributes on an HTMLCanvasElement? Both can be applied at the same time and may have different meanings. I assume that this would justify the html* prefix but we would end up with a svgWidth and htmlWidth animation attribute.

Is there maybe a way to explicitly state that you want to animate a property or an attribute? In case of a presentation attribute it would always fallback to the property? Similar to “attributeType”[1] in SVG animations?
