Here you can see how a Divi builder regular section fits within the framework of the GeneratePress page template. I have set a 4px corresponding colored border on the Section, Row & Module to match those elements in the Divi builder so you can see where their borders are positioned in relation to each other by default. The row sizing in this instance is set to 100% & 1600px max width. The default container width is set to 1200px in the customizer, so Divi’s row sizing & padding settings work flawlessly. Notice no added Divi pixels, (like where they make the default bottom margin 8 px more than the top). Everything is pixel perfect, and adjustments are pixel perfect without guessing..
