* « IE6 is not one browser. It’s a collection of hundreds of browsers, with various languages, patch levels, ISP customisations, extensions and options. Each one has it’s own bugs, and a site that works perfectly in one is not always going to work in them all, especially if you’re playing clever tricks with the brower support for obscure aspects of CSS and Javascript. » (« paranoidfish »:http://www.paranoidfish.org/notes/2003/11/11/2137)
