Grids are all around us. Think websites. Think even more about responsive websites. Think printed newspapers, magazines and catalogs. Think Mondrian. I have a dog-eared copy of Massimo Vignelli and Peter Laundy’s Graphic Design for Non-Profit Organizations produced in 1980 for The American Institute of Graphic Design (AIGA). It featured grids and not only mere grids but the gold standard of grids.
A grid helps to organize content (both text and visual). When a grid is formatted it also organizes the hierarchy of content.
