The Visual Builder Basics
Divi’s power lies in the Visual Builder, a drag and drop page builder that allows you to build just about any type of website by combining and arranging content elements.
The builder uses three main building blocks: Sections, Rows and Modules. Using these in unison allows you to create a countless array of page layouts. Sections are the largest building blocks, and they house groups of rows. Rows sit inside of sections and are used to house modules. Modules are placed inside of rows. This is the structure of every Divi website.
