It looks like you're trying to use Bootstrap 3 markup, but are referencing Bootstrap 2 css files. For example, I see that you're including bootstrap-responsive.min.css
, and this is not part of Bootstrap 3.
Why don't you try referencing the Bootstrap 3 files from Bootstrap CDN? The only link you need for css is http://netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css
