It's a new year, which means its time for a new theme! I'm sure there are some bugs left to work out, but this new theme is CSS3 up the wazoo, with a ton of neat new features like some effort put into implementing a "responsive design" that changes with page sizes.
I've only tried the new theme in Firefox 17 and Internet Explorer 10 for now. I'm pleased to say that everything just works in IE10. All the CSS3 things that I'm doing in Firefox worked exactly the same in IE10. Nice!
That leaves Safari that requires browser-specific hacks, as Safari does not yet support linear-gradient. Well, whatever. I'm not going to deal with that.
