Campus Suite uses the Bootstrap framework for the grid. As long as your design follows their standard 12-column grid, you'll be good. If you have areas with a custom breakpoint, please indicate in the help/text file. If its something very custom, a quick web-session scheduled with a designer might be the best first step. A wireframe indicating any specific reflow/breakpoints would be helpful and the mobile design will help us make any decisions as we develop and compare to the desktop design. If nothing is defined we will make sure to do our best in the build phase to ensure elements and sections break when needed, based on the designs (mobile and desktop).
