I want to create a webPage using HTML 5 which will use all the attractive features of HTML5 i.e. audio, video, autofocus, placeholder, required, email, url, number etc. and the webPage should also have support for the browsers which dont support HTML5 like IE or some versions of other popular browsers such as Chrome, Firefox, opera etc.
How do I start working on that, as You might guess that this is just for the experimental purpose and I am supposed to it asap… so please suggest me any help, site or blog or tutorial or example.. I have seen hhtml5Doctor.com and diveintohtml5.ep.io … the sites are of great help…
Use progressive enhancement. The diveintohtml5 already tells you how: http://diveintohtml5.ep.io/detect.html
