This specification defines the 5th major version, second minor revision of the core language of the World Wide Web: the Hypertext Markup Language (HTML). In this version, new features continue to be introduced to help Web application authors, new elements continue to be introduced based on research into prevailing authoring practices, and special attention continues to be given to defining clear conformance criteria for user agents in an effort to improve interoperability.

Status of this document

This section describes the status of this document at the time of its publication. Other documents may supersede this document. A list of current W3C publications and the latest revision of this technical report can be found in the W3C technical reports index at https://www.w3.org/TR/.

This document was published by the Web Platform Working Group as a Working Draft. This document is intended to become a W3C Recommendation.

The Working Group aims to make this specification reflect the "leading edge" of what is interoperably deployed as HTML. Features which are shown not to have implementation may be removed from this specification.

The Working Group also has a goal, to the extent possible, of modularising the HTML specification.

The Web Platform Working Group expects to recharter in late 2016 and produce an HTML 5.2 Recommendation in late 2017.
