Twitter's Bootstrap 3 grid, changing breakpoint and removing padding

Question

I m trying to move to the new boostrap 3 grid and I m facing some difficulties.

1. How to have the grid to stack below 480px but not between 480px and 768px?

Answer 1

1. Use class .col-ts-12 for all 100% divs under 480px and put this code at the end of bootstrap.css:

   @media (max-width: 480px) { 
       .col-ts-12 { float: none; }
   }
