#### IEMobile 6/7 bug: classes and id not supported on the HTML element

##### December 1, 2009

As it turns out, IEMobile 67 (and presumably anything earlier) doesn’t support classes and ids that are attached to the HTML element. I confirmed this on both IEMobile 6 and 7. Fortunately it looks to be fixed in IEMobile 8 (which makes sense, since it works fine in desktop IE6, which it’s based on).

The consequence of this is that adding an id/class to the html tag will result in the style not being applied to the document:

<!doctype html>
<html id="a" class="b">
</html>
