Tell Gridulator your web-layout width and the number of columns you want, and it’ll spit back all the possible grids that have nice, round integers. Just the thing for pixel-based designfolk. There are inline previews, courtesy of the canvas element, and when you’re all set Gridulator can crank out full-size PNGs for you, ready for use in your CSS, Photoshop docs, or what have you. And there’s full keyboard control for you snazzy power users.
