responsive-columns
displays its content in a column layout, or a series of
animated pages, depending on the available size.
It is made using Polymer 1.x. It uses app-toolbar and neon-animated-pages.
Apart from the toolbar used for the animated pages, this element makes no assumptions about the used design pattern (i.e. the styling of the columns is up to you).
Note that this element does not use CSS media queries to determine the available size. It measures the width that is really available to your element.
