Hello

To fix the entire header of your Habitat template try replacing the following in your templates scripts.php (../templates/j51_habitat/php/scripts.php)...

<!-- Sticky Div -->

<script type="text/javascript" src="/<?php echo $this->baseurl ?>/templates/<?php echo $this->template ?>/js/jquery.sticky.js" charset="utf-8"></script>

  <script type="text/javascript" >

    jQuery(window).load(function(){

      jQuery("#container_hornav").sticky({ topSpacing: 0 });

    });

 </script>

With...

<!-- Sticky Div -->

<script type="text/javascript" src="/<?php echo $this->baseurl ?>/templates/<?php echo $this->template ?>/js/jquery.sticky.js" charset="utf-8"></script>

  <script type="text/javascript" >

    jQuery(window).load(function(){

      jQuery("#container_header").sticky({ topSpacing: 0 });

    });

    jQuery(window).load(function(){

      jQuery("#container_hornav").sticky({ topSpacing: 165 });

    });

 </script>
