HTML5 is the next generation of HTML.
What
is HTML5?
HTML5
will be the new standard for HTML.
The
previous version of HTML, HTML 4.01, came in 1999. The web has
changed a lot since then.
HTML5
is still a work in progress. However, the major browsers
support many of the new HTML5 elements and APIs.
How
Did HTML5 Get Started?
HTML5
is a cooperation between the World Wide Web Consortium (W3C)
and the Web Hypertext Application Technology Working Group
(WHATWG).
WHATWG
was working with web forms and applications, and W3C was
working with XHTML 2.0. In 2006, they decided to cooperate and
create a new version of HTML.
Some
rules for HTML5 were established:
- New features should be based on HTML, CSS, DOM, and
JavaScript
- Reduce the need for external plugins (like Flash)
- Better error handling
- More markup to replace scripting
- HTML5 should be device independent
- The development process should be visible to the
public
The
HTML5 <!DOCTYPE>
In
HTML5 there is only one <!doctype> declaration, and it
is very simple:
Minimum
HTML5 Document
Below
is a simple HTML5 document, with the minimum of required
tags:
<!DOCTYPE
html>
<html>
<head>
<title>Title of the
document</title>
</head>
<body>
The content of the
document......
</body>
</html>
HTML5
- New Features
Some
of the most interesting new features in HTML5:
- The <canvas> element for 2D drawing
- The <video> and <audio> elements for media
playback
- Support for local storage
- New content-specific elements, like <article>,
<footer>, <header>, <nav>,
<section>
- New form controls, like calendar, date, time, email,
url, search
Browser
Support for HTML5
HTML5
is not yet an official standard, and no browsers have full
HTML5 support.
But
all major browsers (Safari, Chrome, Firefox, Opera, Internet
Explorer) continue to add new HTML5 features to their latest
versions.
