Microsoft: IE 8 may break your web page
“In an IE Blog posting on 10 June, members of the IE team reminded site owners – many of whom had designed their sites to display correctly in less-standards-compliant, prior versions of IE – that they need to “get ready” for IE8 so that their content will “continue to display seamlessly”.
Microsoft decided earlier this year that it will make ‘super-standards’ mode the default with IE8. This is one of three modes which will be supported in IE8. The other two are ‘quirks’ mode, which will be compatible with current IE pages and applications, and a ‘standards’ mode, which will be the same as what’s offered by IE7 and “compatible with current content”.”
