Yeah, for the CSS I don't even have a handler because it just goes right in the head.
I don't usually have more than a few lines.
Perhaps my use case is unusual though, I work on simple web apps, games, interactive simulations. I'm about to get into writing, and I expect a small amount of CSS will be sufficient for that too. Though that would probably expand over time, heh. You want to add a quote, and then a floating image...
