Unfortunately, I'm finding the current documentation/examples for the usage of paper-styles a bit lacking. I'm not an experienced CSS guy (relative newbie actually), so I could really use examples of how to implement Polymer 1.0 application-wide styling in order to be used by all of it's custom elements (i.e. by applying classes to any tags in those custom element's local DOMs). I did this kind of thing relatively easily in Polymer 0.5 using core-styles, but it has changed enough in 1.0 to confuse me, particularly without full docs/examples to work from. It also seems there may be a few ways to accomplish this. I'm also wondering if paper-styles is still considered experimental in 1.0? There are no docs or examples for it's use in polymer 1.0 online element catalog (<https://elements.polymer-project.org/elements/paper-styles>), although I did come across 'some' on it's gitHub repository.
