title: Limiting date range in HTML 5
body: <p>I have a input field with type date </p>
  
  <pre><code>&lt;input type="date" id="datepick" name="mybirthday" placeholder="Birthdate(MM/DD/YYYY)" /&gt;
  </code></pre>
  
  <p>Here I want to limit the date range that the user can choose. To be more specific, I dont want the user to choose a birthdate like 22/08/2015. How can I do this?</p>
