Everything is an element
Polymer puts elements back at the center of web development. With Polymer, you can craft your own HTML elements and compose them into complete, complex applications that are scalable and maintainable.
Polymer from the outside
Polymer provides a comprehensive set of elements—both UI and non-UI—that you can use right out of the box. You can mix and match Polymer elements with other elements, including built-in elements and other custom elements.
Polymer from the inside
Polymer's declarative syntax makes it simpler to define custom elements. Features like two-way data binding, declarative event handlers, property observation, and gesture support help you build powerful, reusable elements.
