CSS. And I’m still pretty amazed, after my recent switch to the Mac, at how productive it is – I can edit the CSS file directly from where it is, under subversion control, and being served by the web server, so it’s just save and reload in the browser and svn ci when i’m happy with the result. Nice. Only downside: I feel bad for these MacRabbit guys, seeling software in US dollars, but living in Belgium, having costs in Euros, while the dollar is falling like a rock. But oh, well, I’m a happy camper – makes it cheaper for me.
