I haven't tried it, but it looks good overall.

Doesn't the latter allow for several indirections? It seems to me the 
two functions are equivalent.

One question: is there a reason to do the (symbol-name value) conversion 
before doing the css--property-values lookup?

Maybe the css-value-class-alist should have symbol keys, not strings.

Sounds good.
