Gotchas in Internet Explorer 8
Internet Explorer 8 (IE8) is at Release Candidate 1, which means it will be released very shortly. IE8 is a brand-new browser and will represent a considerable shift from IE7/IE6; it will follow standards more closely and will offer much improved CSS 2.1 support. However, because of some of these changes, it is also widely understood that IE8 might ‘break’ websites that have relied on IE-specific hacks targeted at previous versions if Internet Explorer.
