I am currently designing bespoke using a blank template and finalising the responsive layouts. Beyond mobile and iPad, I’m looking to set the breakpoints on desktop. However, when I change the the grid to 2 column on 1000px/1200px, it changes my 1400px and so on to 2 column also. Obviously from 1400px upwards I’d prefer a 4 column. How do I unlink my grids per breakpoint / pixel width? I’m sure it’s something simple but not cracked it.
