*notices weird display glitches in Internet Explorer for Windows*
*spends two and a half hours digging through the CSS*
*bashes head into desk*
*reads up on Explorer's lame, braindead, broken CSS rendering*
*spends another half hour beating on CSS*
Jumping Jiminy Christ on a pogo stick, how in the hell did Microsoft ever become the dominant force in the IT industry with such poorly-written, inherently broken, crap software? Internet Explorer...what a festering pile of crapware that browser is! Working around bugs in its CSS support is something of a blood sport in Web circles.
See, this is why all my other Web sites don't use CSS.
*gets it to work, finally*
