That would be useful. I'd like to see built-in support for dynamic CSS generation, but for me to do it, it'd take a bit of a research project on the views subsystem that I don't have time for. It's a different problem from other dynamic files (html, rss, etc) where most of the content is dynamic. In the case of CSS, each file has very different static content, and the dynamic content is a relatively small part of it. > -Eric > > On Oct 6, 2:29 pm, Jonathan Lundell <[email protected]> wrote: >> On Oct 6, 2009, at 1:35 PM, mdipierro wrote: >> >>> It is good practice to put in the CSS only relative urls to other >>> static files.
