Html5 is still under development and is subject to change. It is said that Html 5 will become the standard for web based mark up language. However, not all browsers support it yet. 

List of browsers supporting Html5

Popular browsers like Internet Explorer, Chrome, Safari and Opera offer limited support for Html5. I analyzed some of the popular browsers and used a website called Html5Test.com to evaluate the level of support available in these browsers.

The score given below indicate how well the browser support various HTML5 specifications. The bonus points indicate how well the browser handled some of the video/audio codecs and few other new features. The bonus points are not included in the score since those features are not part of the official HTML 5 specifications. 

Here is the result of my Html5 compatibility test:

Browser Name	Compatibility Score	Bonus Score
Google Chrome	293	13
Opera	258	7
FireFox	255	9
Safari	187	0
Internet Explorer	130	5

You can see that Google Chrome offers the best support for Html5 at this time (June 2011). Internet Explorer 9.0 performs very poor according to the compatibility test by Html5Test.

The compatibility test is not a comprehensive test. This test does not cover all aspects of Html 5 and but is sure to give a rough idea of the level of support available in various browsers. But this test will surely give you some idea on the level of support in each of the browsers.

If you are planning to learn HTML5, your best bet at this time is to use Google Chrome browser for testing.

HTML 5 Tutorials Chapter 1: Introduction

Microsoft is embracing HTML 5 as the default platform for application development for Windows 8. This announcement from Microsoft came as a surprise to the application developers, especially to the Silverlight developers.

Until the announcement of HTML 5 based App model of Windows 8, Html was considered as a set of tags for developing web pages. Html 5 is an upcoming standard and is obviously much more powerful than current version of Html, but no one expected it could be used for serious application development. In fact, I remember complaint from a Silverlight developer: "So far we were riding a horse (Silverlight) and now we are forced to settle with a donkey (Html)". This shows the frustration of developers in Microsoft pushing Html 5 instead of Silverlight.

I am not going deep in to the arguments on whether Microsoft should push Silverlight or Html 5. Rather, I would focus on how to use HTML 5 and how to develop serious applications using HTML 5 and JavaScript.

HTML 5 Tutorials

I will be organizing the HTML 5 tutorials as a series of articles. You can navigate to the next or previous chapters using the "related articles" link in the bottom of each chapter.

You are not required to follow the order in which I have written the tutorials. However, following the series may help you learn in an organized manner. I will be providing several samples, mini projects and source code in some chapters. You will be able to download several HTML 5 sample applications in the upcoming chapters.
