HTML5

---

HTML5 will be the new standard for HTML, XHTML, and the HTML DOM. The previous version of HTML came in 1999. The Web has changed a lot since then. HTML5 is still a work in progress. However, most modern browsers have some HTML5 support.

Some rules for HTML5 were established.

• New features should be based on HTML, CSS, DOM, and JavaScript.
• The need for external plugins (like Flash) should be reduced.
• There should be better error handling.
• There should be more markup to replace scripting.
• HTML5 should be device independent.
• The development process should be visible to the public.

New Features

• The canvas element for drawing
• The video and audio elements for media playback
• Better support for local offline storage
• New content-specific elements, such as article, footer, header, nav, and section
• New form controls, such as calendar, date, time, e-mail, URL, and search
