+* Since [Web Components](http://w3c.github.io/webcomponents/explainer/) allow you to create new types of DOM elements, the DOM tree is very different from other implementations.
 * The template, styling, and behavior are fully encapsulated in each custom element. Instead of having an overall stylesheet (`base.css` or `app.css`), each element that needs styling has its own stylesheet.
 * Non-visual elements such as the router and the model are also implemented as custom elements and appear in the DOM. Implementing them as custom elements instead of plain objects allows you to take advantage of Polymer data binding and event handling throughout the app.
