Does Internet Explorer 8 support HTML 5?

IE8 beta 2 supports two APIs from HTML5: cross-document messaging and non-SQL storage.

IE8 beta 2 doesn’t implement the HTML5 parsing algorithm or the new elements (no <canvas> or <video> support).

There are also bug fixes that align IE8 better with HTML5.

You can get HTML5 tags working in IE8 by including this JavaScript in the head.

<script type="text/javascript">
 document.createElement('header');
 document.createElement('nav');
 document.createElement('menu');
 document.createElement('section');
 document.createElement('article');
 document.createElement('aside');
 document.createElement('footer');
</script>
