<demo-snippet>

demo-snippet is a helper element that displays the source of a code snippet and its rendered demo. It can be used for both native elements and Polymer elements.

<url-bar>

url-bar is a helper element that displays a simple read-only URL bar if and only if the page is in an iframe. In this way we can demo elements that deal with the URL in our iframe-based demo environments.

If the page is not in an iframe, the url-bar element is not displayed.
