title: how to make html5 working with android
body: <p>is the html5 working on android 2.2 and above?
  i was tried a <a href="http://www.youtube.com/watch?v=uVqp1zcMfbE" rel="nofollow">youtube link</a>, but it is working with js.
  they just adding <code>&lt;!DOCTYPE html&gt;</code> that all then say is support html5?
  and i tried to put other html5 coding as below</p>
  
  <pre><code>&lt;form action="/newaccount" method=post
    oninput="up2.setCustomValidity(up2.value != up.value ? 'Passwords do not match.' : '')"&gt;
  &lt;p&gt;
  &lt;label for="username"&gt;E-mail address:&lt;/label&gt;
  &lt;input id="username" type=email required name=un&gt;
  &lt;/p&gt;
  &lt;label for="password1"&gt;Password:&lt;/label&gt;
  &lt;input id="password1" type=password required name=up&gt;
  &lt;p&gt;
  &lt;label for="password2"&gt;Confirm password:&lt;/label&gt;
  &lt;input id="password2" type=password name=up2&gt;
  &lt;/p&gt;
  &lt;input type=submit value="Create account" /&gt;
  &lt;/form&gt;
  </code></pre>
