HTML5 is a new standard for web. You might have seen many websites are now moving new HTML5 technologies.
Almost all Google products like youtube.com,orkut,Google Adsense,bloggers are now delivering HTML5 content to the client.
You may want to identify which are those websites who are delevering HTML5 content. For example, open www.satalaj.com and look at it's page source. You will first notice a element declare here is a doctype which is simple html.
You don't need to specify dtd schema, because HTML5 is not derived from SGML.
Let's see why HTML5 comes into picture. New features are based on HTML,CSS, dom and JavaScript.
It aims to reduce the need for the third party plugins like Flash, Silverlight and ActiveX control. Better error handling mechanisam and more markup to replace scripting.
HTML5 is device independent. The development process is clearly visible to the public. These are the aims of the HTML5 language.
There are introduction to the new element like canvas for 2D drawing video and audio elements for media playback. Previously browser has to
support the browser, you need to download the flash player or silverlight plugins to support these videos and audios.
Support for local storage, new content specific elements like articles, footer, header, navbar and section. New form controls like calender,color pallet, datetime, email and url.
Browser support. Most modern browsers are supporting some of the elements of HTML5. HTML5 is not fully standardized, none of the browser support all the features. Let's start with your first HTML5 tutorial.
I will use Google chrome and Notepad++. Notepad++ you can download it from Google itself. You just need to search and it's free. To begin our first HTML5 we will declair here a doctype, as HTML and here is your Head section end of head.
So, we will start with HTML element end of HTML head and then body slash body.
Inside this element we will say,"Welcome to HTML5 first tutorial".
Now, let's run this in Google chrome.
This is how it looks.
You can view page source and it's doctype is html. In later tutorials we will discuss more about the new features of HTML5. Watch the next video. Thank you very much.
