Huh, I was expecting MutationObserver[1] (which is the 'proper' way to do this, by the way). Not sure about the performance though - MutationObserver probably comes with more overhead.

Yup, that's certainly another option. Haven't tried it, but I would say that the asynchronous nature of mutationobserver would make this blink the elements before animating them.

In my experience you can change an element with a Mutation Observer before it is rendered.

cool, in that case I'll definetly try it.
