Any error message? I'm guessing this is because of the .css and .js files references issues or JavaScript error. You have one stylesheet pointing to C:\httpdocs\css\stylelogin.css. Try update all the reference to use absolute link for now. example:
ref="http://yourhosting.server/css/jquery-ui.css"
<link rel="stylesheet" href="..\css\jquery-ui.css" />
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

<script src="..\js\jquery-1.11.1.min.js"></script>
<script type="text/javascript" src="../js/jquery-1.11.1.min.js"></script>
