HTML 5: The Markup Language (ARIA Edition)

Unofficial Editor’s Draft 24 April 2012


The content of this document is also available as a single HTML file.


This specification describes the fifth major version of the HTML language and provides the details necessary for producers of HTML content to create documents that conform to the language, as well as describing a speculative integration of ARIA attributes into the language. By design, it does not define related APIs nor attempt to specify how consumers of HTML content are meant to process documents.
