Re: [csswg-drafts] Dynamic values support?

Unfortunately, this sort of thing isn't possible in general. Lots of properties depend on each other, both within a single element and *especially* between elements, with the between-element dependencies often being quite complex. Introducing *more* dependencies into this graph can easily make the entire thing intractable; even when there is a unique solution (rather than zero or multiple possible solutions), it's often not obtainable thru the efficient layout algorithms we use today, instead requiring a more generic constraint-satisfying search algorithm, which can run into exponential time blow-ups.

The JS you write is less of a performance hit than what would happen if we recast the entire style system to handle this sort of thing. ^_^
