Multiple animations

[turbolent]

The book explains how to define and use keyframe animations:
https://japgolly.github.io/scalacss/book/features/keyframes.html
How is it possible to apply multiple animations to a selector?
In plain CSS this would be e.g. animation-name: kf1, kf2.

Taking the book as an example, how would the definition of anim1 with multiple animations look like?

Thanks

@japgolly Any idea how this could be done?
