I've run into a bit of a roadblock using the Omega theme. There doesn't seem to be a way to control the column width and prefix/suffix settings between breakpoints. For example, I might want the branding region to be a column width of "6" in the 768 breakpoint, but I want it to be a full "16" column width in the lower 480 breakpoint.
Since drupal hardcodes the "grid-6" into the region as a class ,all I can think to do is override a "grid-6" class to function as a "grid-16".
Does anyone know how to stop Drupal from adding the grid classes? Has anyone come up with a better solution?
