I Blame Microsoft
This is what Tim Bray writes about IE:
The problem isn’t that CSS is too hard. The problem isn’t browser incompatibilities in general. The problem is specifically that Microsoft Internet Explorer is a mouldering, out-of-date, amateurish, out-of-date pile of dung. Did I say it’s out-of-date? As in past its sell-by, seen better days, mutton dressed as lamb, superannuated, time-worn. It’s so, like, you know, so twentieth-century.
