Looks like there are four frameworks[0]. Use the Android one for Android, the Polymer one for Polymer, the Angular one for Angular, and the "Material Design Lite" would have to be adapted for everything else - it is plain css, html. Don't know if the Material Design Lite has any JavaScript library.
I hate if I start using a lib, which is kind of half finished and then learn a few month later that work on this project has been stopped and I should use now the new shiny fade of the day successor which is also half finished. Seems to be the standard in the JS world where people change frameworks and libs more often then their underpants.
