Things came to a head in a workshop meeting in 2004. Ian Hickson, who was working for Opera Software at the
time, proposed the idea of extending HTML to allow the creation of web applications.
The proposal was rejected.

Some things are clearer with hindsight of several years.
It is necessary to evolve HTML incrementally.
The attempt to get the world to switch to XML, including quotes around values and
slashes in empty tags and namespaces all at once didn't work.

HTML5 is gaining momentum. New elements have been specified, but in practice Internet Explorer versions 6-8
pose a problem, as they fail to recognize unknown elements; the new elements are unable to hold children and
CSS has no effect on them. This depressing fact was posing quite a hindrance to HTML5 adoption.

BTW, if you want CSS rules to apply to unknown elements in IE,
you just have to do document.createElement(elementName).
This somehow lets the CSS engine know that elements with that
name exist.

Ian Hickson, was as surprised as the rest of the Web.
Having never heard of this trick before, he was happy to report:
‘This piece of information makes building an HTML5 compatibility
shim for IE7 far easier than had previously been assumed.’
