Here's a CSS-only solution:
- makes .container 970px wide (default)
- translates col-sm-, col-md-, col-lg-* to col-xs-*
- translates col-sm-offset-, col-md-offset-, col-lg-offset-* to col-xs-offset-*
- unhides .hidden-xs, .hidden-sm, .visible-xs[-] and .visible-sm[-] (new in 3.2.0)
- makes navbar unresponsive
- unlike Javascript overrides, preserves original .col-xs-* columns when toggled off
All you have to do is add link this CSS file and the class unresponsive to the `` tag.
