CSS

Here is an idea that I had, when I was designing a website for a friend, about CSS standards and browser implementations. Opera, Safari and konqueror all render extremely well; Firefox is pretty good but still has some bugs; and Internet Explorer just sucks ass. I always have to break the standard by adding special '_' css rules that only IE parses. It annoys me slightly because it is not standards compliant, but it is incredible useful because I can now override the real rules with special IE rules.
