IE 9 Preview 4 – How much HTML 5 support? Should it?

with one comment

I’ve been wondering how to get thru the hype of Html 5 support in IE 9. That’s not to say that the improvements they have made aren’t welcome – they very much are. But Html 5 is larger spec than just audio, video and canvas – and I’ve been wondering how broad Html 5 support goes.

I found a site called http://html5test.com/ that will test your browser for HTML 5 support. How does IE 9 preview 4 fare?

That’s right – 96  out of 300? You say you want details? Here you go:

Clearly, while the IE team has done great work in bring IE forward with the IE 9 previews, clearly there is a lot more HTML left unsupported then currently in the latest preview. But should IE 9 have full HTML 5 support? Good question. If you take a look at the HTML 5 document at the W3C you’ll notice it’s “working draft” – the proposal in still flux. I would guess that MS is just expanding “de facto” standards support and hitting the highlights, where other features such as IndexDB, Web Applications, Html 5 Forms and other elements will come – eventually. But will they come in IE 9? Only MS knows the answer to that one. Let’s just hope we don’t have to wait three years until IE 10 to find out.

  1. It is great news to the education, science, engineering, and accessibility communities that MathML is part of HTML5. And even better since all the browser vendors seem to be in favor of it. Unfortunately, the latest Platform Preview of IE9 has broken their MathML support. See the details in “MathML in HTML5: Internet Explorer 9 is Broken” (http://news.dessci.com/2010/08/mathml-in-html5-internet-explorer-9-is-broken.html)
