Does anyone know exactly what versions of browsers support this? DIV's are awesome, but I'm always afriad to use them because I *think* that only 4.0 browsers or later will see them right. They're sort of a big deal, because if the positioning doesnt work, it almost always results in a garbage, unreadable page.

Does anyone know exactly what browser version of both IE and Netscape started supporting DIV layer positioning with CSS2?
