Before the invention of movable type and printing, simple grids based on optimal proportions had been used to arrange handwritten text on pages. One such system, known as the “Villiards Diagram,” was in use at least since medieval times. Interior designers arrange rooms based on a grid system, and city planners work on a grid too. It’s a wonder what took web designers and developers so long to show interest in a system that has been essential to the printed word since the ‘30s.
