title: Use of html5 in web app
body: <p>I have a web app which has standard things for learning based app like student reg, teacher reg, assignments, lessons, content, reports, etc</p>
  
  <p>This uses Java in the middle tier.</p>
  
  <p>We are planning to redesign this app which would mainly mean changes in presentation layer. Now we plan to havr the same html work on both desktop and iPad, through adaptive css...i am completely aware of the css stuff..media queries and all.</p>
  
  <p>My question is should i use html5 for the new pages..i have not used it much..but wanted to know what benefits does it offer apart from the standard audio, video support and the obvious things.</p>
  
  <p>I have a lot of AJAX calls in my app. Will html5 help in any way for that?</p>
  
  <p>I wanted to know some good reasons for using html5, given the same page is going to render with slight differences on desktop vs iPad.</p>
