Microsoft reported recently that several hacks that were implemented by designers to survive IE6 will stop working under IE7. This is not great news for designers, as it means that those of us who have implemented such hacks will be looking at hours of unpaid work cleaning up code for IE7. And, the situation could get downright messy as people transition from IE6 to IE7. Microsoft is allowing organizations to block the installation of IE7 if they use Automatic Updates.
So we could be looking at another series of conditional CSS pages, some of IE5, some for IE6, and some for IE7.  The Star-HTML hack is out the window, and with it goes the Holly Hack.
One can only wonder what will happen to the CSS Zen Garden.
