The shortest way I think is to move:
<script src="js/jquery.dropotron.min.js"></script>
<script src="js/skel.min.js"></script>
<script src="js/skel-panels.min.js"></script>
<script src="js/init.js"></script>
<script src="js/index.js"></script>
to the top of the page. You have some css in "js" files and thats why unless js is loaded - you see this pure HTML code.
Edit: of course make sure jquery.js is before that ;).
