title: Html5 form element "required" on iPad/iPhone doesn't work
body: <p>iPad safari is supposed to be html5 compliant, but it seems that the required element doesn't work. Anyone know why, or have a decent workaround that doesn't require a ton of JavaScript?</p>
  
  <p>My code</p>
  
  <pre><code>&lt;input type=email class=input placeholder="Email" name="email" required&gt;
  </code></pre>
