/**
 * 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.
 *
 * * For even more examples, see
 * [Dart HTML5 Samples](https://github.com/dart-lang/dart-html5-samples)
 * on Github.

/**

 *
 * To useCapture on events:

 *
 * Custom events can also be accessed as:

  * The simplest way to get the contents of a text file, such as a

/**
 * The type used by the

 * Top-level container for the current browser tab or window.

 * [Window] object. A [Window] contains a [Document] object, which contains this
 * web page's content.
 *
 * Use `window` to access properties of the current window. For example:
