  • Well HTML5 is an enhancement of HTML 4 (both trying to spell out and precisely define existing features as a well as trying to innovate) so a browser like IE 8 does certainly support some features that HTML5 specifies, not necessarily as it was released with HTML5 support as an objective but simply as the HTML 4 or CSS or DOM stuff implemented remains part of HTML5.

    So what features exactly are you looking for? You can check the MSDN documentation on IE's HTML and CSS support to check whether your favourite HTML5 feature is already supported in some older IE version like IE 8.

  • Hi,

    semantic html5 elements are supported in all versions of IE... see

    as explained in that sample you use <object> tag fallbacks for <video> and <audio> tags which are not supported in IE8 and lower. SVG is support in IE8 and lower with the Adobe SVG document addon. (some covenants)

    the new HTML5 form element attributes (time, date etc) can be replaced with either ActiveX, applets or web controls (see

    other css 3 support can be implemented in earlier IE versions with shims such as jQuery and Lightbox. (rounded corners, text shadow)

  • All the things IECUSTOMIZER mentions are in fact Hacks so no new things are really supported. And because of the very slow javascript engine of IE 8 it will only make your webpage very slow for these users.

    If the web wants to stay up-to-date everone should stop using IE. Even the newer versions will someday be outdated and can't be updated because you will need Windows 9 or something like that.

  • Even IE11 doesn't support all the HTML5 and CSS3 features.

    You can see what is supported by any browser on any platform at:
