Outlining

The HTML5 specification describes an algorithm to determine the outline of a web page. This allows:

  1. User agents (e.g., browsers and screenreaders) the ability to present data to the consumer in a logical way.
  2. Syndicators to syndicate portions of a page's content in a structurally meaningful way.
  3. Authors to create pages with any number of heading levels.

While this feature is useful, it is poorly implemented in modern versions of all browsers at the time of this writing. For those interested in investigating HTML5 outling in more detail, we suggest checking out the HTML5 Outliner project, offering Chrome and FireFox browser extensions to display outlines, and more detailed background information from the W3C.
