title: Three.js - mixing WebGL and CSS3D with iFrame
body: <p>I prepared a working page that mixes <code>WebGL</code> and <code>CSS3D</code> (with a little help from SO <a href="https://stackoverflow.com/questions/24681170/three-js-properly-blending-css3d-and-webgl/24688807#24688807">here</a>), and it works great. I throw in an <a href="https://dl.dropboxusercontent.com/u/728316/demos/css3dwebgl/example2.html" rel="nofollow noreferrer">iframe</a> for good measure:</p>
  
  <p>But it lacks the ability to interact with the iframe.</p>
  
  <p>In mrdoobs pure <code>CSS3D</code> <a href="http://mrdoob.com/lab/javascript/threejs/css3d/" rel="nofollow noreferrer">demo</a> one can even scroll the pages and mark text etc:</p>
  
  <p>As it seems, the combination of <code>WebGL</code> in front of the <code>CSS3D</code> renderer hinders the interaction. Is there a way around this?</p>
  
  <p>Thanks,
    Dirk</p>
