support @keyframes {...} (for css animations)
Ongoing work, I'm not entirely sure I'm doing this right. See comments.
It's kind of working but now I'd like to understand what you mean about warnings and how you imagine I should deal with them.
The hart of the problem is here I think : https://github.com/nomalab/elm-css/blob/master/src/Css/Preprocess/Resolve.elm#L156-L181 where we "resolve" the keyframes.
I imagine that I should do a better job at converting Preprocess.Mixin to Structure.Property and detect misusages like nesting snippets etc... Do you agree ?
Can someone please give me some feedbacks on this, so that I can complete the work?
Any update on this? Full animation support in elm css would be very good. I can help too.
