What is HTML5?
HTML5 will be the new standard for HTML.
The previous version of HTML, HTML 4.01, came in 1999. The internet has changed significantly since then.
HTML5 is intended to subsume not only HTML 4, but also XHTML 1 and DOM Level 2 HTML.
HTML5 is designed to deliver almost everything you want to do online without requiring additional plugins. It does everything from animation to apps, music to movies, and can also be used to build complicated applications that run in your browser.
HTML5 is also cross-platform (it does not care whether you are using a tablet or a smartphone, a netbook, notebook or a Smart TV).
HTML5 can also be used to write web applications that still work when you are not online.
The HTML 5 working group includes AOL, Apple, Google, IBM, Microsoft, Mozilla, Nokia, Opera, and hundreds of other vendors.
HTML5 is still a work in progress. However, all 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
- The need for external plugins (like Flash) needs to be reduced
- Error handling should be easier than in previous versions
- Scripting has to be replaced by more markup
- 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:
<!DOCTYPE html>
Minimum HTML5 Document
Below is a simple HTML5 document, with the minimum of required tags:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Title of the document</title>
</head>
<body>
Content of the document......
</body>
</html>
<html>
<head>
<meta charset="UTF-8">
<title>Title of the document</title>
</head>
<body>
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.
