Dynamic CSS

So the big thing I've been working on lately is dynamic CSS. Its very simple - just using variables and templates to generate CSS on the fly.The cool thing about this strategy is that it has some side benefits - element id's can become hooks for testing, and the structural data used to generate the CSS can also be used to generate HTML structure, like columns, div layouts, and spans.Its still a work in progress, but I like what I see so far.
