  2. World Wide Web Consortium (W3C) is in charge with delivering the HTML5 specification.
  3. Internet Engineering Task Force (IETF) is in charge of the development of HTML5 WebSocket API.

Techopedia Explains HTML5

HTML5 is an effort is to bring order to web development chaos by organizing common practices, embracing implementations from various browsers. It is massive, with over 100 specifications as part of the HTML5 specs. Understanding this, you can simplify by thinking of HTML5 this way. HTML5 is simply just an umbrella term for the next generation of web apps an how functionality will be expanded with better markup (HTML), better style (CSS), and better interactivity (JavaScript).

The specification of HTML5 that has been published currently is not yet final. HTML5 is expected due for Candidate Recommendation (CR) by 2012, and is expected for Proposed Recommendation (PR) by 2022. However, this doesn’t mean that HTML5 is not ready for use. The proposed recommendation does mean however that there will be two interoperable implementations. As of 2011, browser vendors are actively adding support for new features of HTML5.

New features of HTML5 include:

  • New parsing rules that are not based on SGML but are oriented towards flexible parsing and compatibility.
  • Support of use of inline Scalar Vector Graphics (SVG) and Mathematical Markup Language (MathML) in text/html.
  • New available elements include article, aside, audio, bdi, canvas, command, datalist, details, embed, figcaption, figure, footer, header, hgroup, keygen, mark, meter, nav, output, progress, rp, rt, ruby, section, source, summary, time, video and wbr.
  • New available types of form controls include dates and times, email, url, search, number, range, tel and color.
  • New available attributes of charset on meta and async on script.
  • Global attributes that can be applied for every element that include id, tabindex, hidden, data-* or customer data attributes.
