title: Polymer - is it possible to substitute bootstrap with it?
body: <p>I used polymer paper elements individually before, but is it possible to use it to build a whole responsive website(nothing extraordinary, just a usual website)? I'm asking because it does not have grids, containers, and I don't quite understand the iron-flex-layout or whatever. Anyone used it like this before? Is the outcome good and responsive? I guess the Polymer Starter Kit would be the starting point.</p>
