HTML as a UI is geared towards making documents and displaying text and graphics in a rigid layout/format. It's not geared, imho, for a UI with lots of interactivity - e.g., imagine trying to implement blender or an audio processing app (like audacity) in html/css. You'd basically be creating new primitives on top of html, and build your UI on that (or install one of those UI libraries that _renders_ to html).
