IE7
Gotta give IE7 some serious Google juice. This has got to be one of the most important hacks of the IE5-6 era. Even after understanding what the magic Javascript does, I’m still amazed that it manages to fix so many of the rendering bugs IE. At some point I’m going to scrap my IE-specific workarounds for this site and just use proper CSS and the IE7 patch for those unfortunately souls stuck with Internet Explorer.
