title: HTML5 Email Validation
body: <p>It is said "With HTML5, we need no more js or a server side code to check if the user's input is a valid email or url address"</p>
  
  <p>How can I validate email after a user enter? and without JS how to display a message if the user enter a wrong form of his/her email address.</p>

  &lt;input type="submit" value="Submit"&gt;
  </code></pre>
