Wither the Star-HTML Hack?

Bergevin, Holly and John Gallant
Position is Everything

Abstract:

Recently the Microsoft blog told us that some of our CSS hacks will stop working in IE7, a fact we detailed in our first IE7 article. While this is generally good news, it is a bit disturbing that the Holly hack in particular will cease to function while many of the layout problems it is meant to fix will still be there, and will still need fixing.
