What I would like to see is an html/css/js framework like bootstrap or groundwork that is completely generic, with no styling at all; just a wireframe that lays everything out as it should. Then provide the ability to customize the look either manually or by some gui on the web. Otherwise you get a raft of "bootstrap" sites out there that all look the same unless a front-end dev goes through the painstaking process of overriding the default styles of the framework.
