Does it bother the crap out of anyone else that Mozilla and IE render .75em as .7em and .77em as .8em (for example), at least on paragraph tags?
And so if you want to make your site accessible by using em on font sizes, you have to go in .1 increments, which doesn't give enough control
And also equally annoying that Safari renders 1em much larger than Mozilla or IE? (at least with verdana font)...
