You're welcome. I think it's a generally useful capability, and I hope that there's a more elegant way of incorporating it into web2py. As I was saying somewhere else, a generic.css file doesn't really work (unless you're generating all your CSS content in controllers). At the very least, perhaps the logic (where?) that creates the default html headers could recognize that it's got a .css file and create css headers instead. > > On Oct 7, 8:19 am, Jonathan Lundell <[email protected]> wrote: >> On Oct 6, 2009, at 2:54 PM, Eric Vicenti wrote: >> >> >> >>> Thanks, mdi and Jonathan.
