Recently I’ve been working on making a valid, semantic and accessible HTML5+CSS3 page out of a bag I’d seen in a local supermarket). I’m using Chromium most of the time, because it updates often and has support for the most cutting-edge stuff as well.
The problem is, other browsers don’t. So even though it looks all nice and nifty on my screen, if i reboot and check it on Windows, the situation gets complicated. Luckily IE 9 supports everything i need for the design (more or less), except for the text-shadow property, but that’s just enough punishment for people using IE.
