Hello
Presuming I understand you correctly you could try replacing the following in your templates scripts.php (../templates/j51_enlighten/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: 65 });
});
jQuery(window).load(function(){
jQuery("#container_header").sticky({ topSpacing: -20 });
});
</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_hornav").sticky({ topSpacing: 127 });
});
jQuery(window).load(function(){
jQuery("#container_header").sticky({ topSpacing: 42 });
});
jQuery(window).load(function(){
jQuery("#container_spacer1").sticky({ topSpacing: 0 });
});
</script>
