HTML Viewer capabilities

[Christoph Schneegans]

Hello!

Is there a complete and up-to-date list of which HTML and CSS features the HTML Viewer control supports or, even better, which it does _not_ support? It seems that e.g. the universal selector as in

<style type="text/css">
* { color: blue; }
</style>

is not supported. I don't expect the full functionality as in IE or Firefox, it just would save me time when creating the progess billboard.
