In response to a request here are a few of my Actions that I use on a daily basis. I have a library of Actions for quickly adding the Divi grids to my PSDs. It’s hugely useful for me and other developers might get some use out of them too.
Some notes: The actions are meant to work with my document size of width 1900px. Document length can be any size.
Also please note these actions are only the guides for the grid. When you run this action it will remove all your current guides and replace them with the grid you have chosen. They were created to work with the default Divi grid.
