Hi

I love Codrops scripts:

What should you do?

You have the burger icon with the menu inside a layer:

<div class="menu_container">
  <a href="#" class="menu_button">Menu icon</a>
  <div class="menu">
    <ul>
      <!-- Your menu -->
    </ul> 
  </div>
</div>

With this CSS:

.menu_container {
  position: fixed;
}

.menu_container .menu {
  display: none;
}

Finally you should toggle the menu when the burger is clicked:

jQuery(document).ready(function() {
  jQuery('.menu_button').click(function() {
    jQuery('.menu').toggle();
  }
}

Hope it helps you
