Having worked extensively with Susy, I recently encountered a unique use case that has left me puzzled. To illustrate my point, let's take Twitter as an example.
If we observe their website layout, they have a standard three-column design with a breakpoint at 1250. Once this threshold is crossed, the entire rightmost column 3 shifts below column 1.
I am curious about achieving this effect using pure CSS in Susy 2. Upon inspecting Twitter's implementation, it appears as though they are physically relocating the content from column 3 to column 1. While JavaScript might be involved in their process, I am interested in exploring cleaner alternatives. Any suggestions?
