Mobile view isnt working correctly

hey guys been using this theme for awhile and loving it

the only problem im having is my website looks odd in mobile view. The content area works fine but the header and footer shrink in size and look funny.

Also how do i disable the default zoom in on a mobile device? id like to zoom out and just have it as a standard page in mobile view.

Thanks in advance!
