Internet Explorer and “Quirks Mode”

A few years ago, someone at Microsoft had a brilliant idea to create something called “Quirks Mode” for Internet Explorer. The reasoning behind it is still a bit beyond me, but apparently it has to do with trying to make the browser render old Web sites the way they were initially intended to look. Basically, “quirks mode” turns all versions of IE into IE 4 (as it essentially attempts to render the page the way it would have been rendered with IE 4, ignoring quite a bit of CSS and XHTML).
