After implementing the code in the following manner:
<link href="css/bootstrap.css" rel="stylesheet" type="text/css">
<link href="css/bootstrap-responsive.css" rel="stylesheet" type="text/css">
<style type="text/css">
.container{
max-width:980px;
}
</style>
</head>
<body>
<div class="container" style="max-width:980px;">
...
</div>
</body>
</html>
Despite the specified max-width of 980px for the container, it ends up extending beyond 1100px.
