It seems like I did something wrong, because respond.js isn't working in IE8. I've placed html5shiv and respond.js as last element into my head, but it is just not loading. I don't get any errors, and the page is valid HTML. Anyone can point me to the problem: http://hypnosewien.at/responsive/
Here is my head:
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">
<title>Hypnose Wien</title>
<!-- Bootstrap -->
<link href="//maxcdn.bootstrapcdn.com/bootstrap/3.3.1/css/bootstrap.min.css" rel="stylesheet">
<link href="css/core.min.css" rel="stylesheet"/>
<!--[if lt IE 9]>
<script src="js/html5shiv.min.js"></script>
<script src="js/respond.min.js"></script>
<![endif]-->
</head>
Both files exist. I also tried to pull jquery up before those two scripts. Still not working.
