Interesting ideas David,
I work with css and html every day so I'm interesting in CSS because it's a
good technology for style purposes. Another really cool project is
http://lesscss.org/. I like the idea of a combination of CSS and LESSCSS
into one plugin (or 2) for GeoServer because I guess it's a really good way
to develop styles in a fast and maintainable way.
My idea is to preprocess the CSS files and to generate one big SLD. Do we
have any way to isolate the css plugin and run it in batch mode?
Regards
