-### What Are The Limitations ?
Unfortunatly it isn't all pink, WebGL and HTML aren't really merged.
This is only a nice trick. It has some limitations.
For example, the dom element is rotated using [css 3d](http://example.com/TODO).
This is a fairly new technology.
So you may hit bugs.
Moreover, it only appears as a part of 3d... but this remains plain DOM.

For example, it is impossible to get
[post processing](http://example.com/TODO)
on the dom element.
Indeed, this technic is applied in 2d on the rendered scene and the DOM element is not in it.
Additionally the dom element won't share the lighting as the rest of your webgl scene.
Nevertheless, [css shader](http://example.com/TODO) allows you to apply shader on normal DOM element,
so it may be possible to make a coherent lighting.
