 		<div class="desc">[name] is a simplified version of [page:CSS3DRenderer]. The only transformation that is supported is translation.<br />
 			The renderer is very useful if you want to combine HTML based labels with 3D objects. Here too, the respective DOM elements are wrapped into an instance of *CSS2DObject* and added to the scene graph.<br />
-			Unlike [page:CSS3DRenderer], orthographic cameras are supported.
