 * HTML elements and other resources for web-based applications that need to
 * interact with the browser and the DOM (Document Object Model).
 *
 * This library includes DOM element types, CSS styling, local storage,
 * media, speech, events, and more.
 * To get started,
 * check out the [Element] class, the base class for many of the HTML
 * DOM types.
 *
 * ## Other resources
 *
 * * If you've never written a web app before, try our
 * tutorials&mdash;[A Game of Darts](http://dartlang.org/docs/tutorials).
 *
 * * To see some web-based Dart apps in action and to play with the code,
 * download
 * [Dart Editor](http://www.dartlang.org/#get-started)
 * and run its built-in examples.

 * [Dart HTML5 Samples](https://github.com/dart-lang/dart-html5-samples)
