grid to 1200 width

Hi, I edited the grid to be 1200 (still divisible by 16) and it’s working great on the desktop version. I didn’t think I would need to edit the responsive grid css since I wanted to keep those settings, but when I look on mobile it’s too big. I’m thinking there must be something that needs to be edited there as well, but don’t see it. Can you point me in the right direction? Site is at http://vi-bedigital.com/crosspoint/

Thanks!
