From Slashdot Ask Slashdot Story | Is Internet Explorer 6/7 Support Required Now?
Re: (Score:3, Interesting)
For basic websites, I highly recommend Universal IE6 CSS [google.com].
I’ve decided that I will never design a website that supports IE6, but instead will only server up this rudimentary (if nice-looking) style sheet. As long as your website is standards-based, compliant, and content-oriented, this CSS file works great. You do, however, have to include some of those annoying <!– [if lt IE 7]>…<![endif]–> tags.
For web apps, which are more complex, then I use a browser sniff and redirect IE6 users away.
