I changed screen.css this morning. This page is now more compatible with IE, although every piece of code is still messed up. At Bugzilla they are working on the generated content bug, which Opera currently handles the best; with the exception for ::first-letter. I also used another CSS3 selector. The :empty pseudo-class. I used it format my calendar table:
td:empty{
color:inherit;
background:#fff;
}
It's really simple, every td, which is empty gets a white background instead of a grey one. This is currently only supported by Mozilla, but maybe Opera will support this soon. I have also chosen another background Image from squidfingers / patterns, these guys are really nice! And they have a terrific CSS file!
