DOCTYPEswitch has stood designers and developers in good stead as a toggle between standards mode and quirks mode. But when IE7, with its greatly improved support for standards, "broke the web," it revealed the flaw in our toggle. The quest was on to find a more reliable ensurer of forward compatibility.
