Very interesting css preprocessor/layout engine combination, kudos 1999. Many people annoyed with css might love this quite a bit. I wonder about the performance implications. The layout engine obviously has to run in javascript and thus it will result in a slower startup time (gss has to parse the logic) and the layout itself will be obviously slower than "native css".
