I use Araneae myself. It has code highlighting for HTML, CSS, PHP, Javascript and probably others (which I don't use). It's a very light small program but has a few minor bugs and for some bizarre reason doesn't support switching tabs with CTRL-TAB, but otherwise it s a very good program and I recommend it.

I quite like gEdit on linux, it's also very small, light and efficient. The code highlighting is easily customisable too which I like and it doesn't have any bugs - or at least I've never found any.
