About Gridline — Layout Grid Overlay

Design and overlay a pixel-accurate column grid — wrapper widths, gutters, and gaps — on any page, per breakpoint. I was sick of not having my own custom overlay where i can set content wrapper sitewrapper, gap, number of cols, padding, margins, for every breakpoint and look at my site with that sort of overlay information. Now i have it. And now you do too.
