Jake Bunce provided me with a whole lot of excellent code for EXTRA.css which designs the Category bars, and the node titles and background colours within them. But it's all rather bulky - lots of sections of code per category. I also have some other sections that are bulky and belong all together. I would like to move such sections into another css file and use an include. But if I use Create Template I don't think that makes a css file? So how do I do that?
