Steps 1 (remove viewport) and 2 (static container width) are easy enough. But how do I set the media query breakpoints in CSS?
There's an option in Bootstrap to customize your download of Bootstrap CSS to fit your needs. If you press the link customize along Bootstrap's website, it will take you to a page that lists all the components and utilities that come included with the default download of Bootstrap CSS. You can add/remove any of these items to create a version of bootstrap that fits your particular needs.
For you case, remove the following options (Under Common CSS):
There is also a section where you can customize and compile the LESS variables into a custom .css file. The one you could consider changing is the Media Query Breakpoints settings, but there are lots of customization options for you to browse through.
Take a look here at Bootstrap/Customize to see all the options you can change, and hopefully that will help!
