Divi's greatest tool is the use of it's visual mode, which allows you to build your pages on the front-end of your website. Letting you see every change in real time before it is saved and published.

What Is The Visual Builder?

The Divi Builder can operate in two forms: The standard “Back-end Builder” located on the admin panel dashboard and the front-end “Visual Builder.” Both interfaces allow you to build the same exact types of website designs with the same content elements and custom settings. The only difference is the interface you use to make the changes. The Back-end Builder lives inside of admin panel dashboard and it can be accessed along with all of the other standard WordPress settings. It sits inside the WordPress UI and replaces the standard WordPress post editor. It’s great for making quick changes while you are inside the dashboard, but it’s also confined by the dashboard and is rendered as a block-based representation of your website. The visual builder on the other hand allows you to view changes in real time on the page you wish to make changes on. Starting by enabling the visual builder on the top right.
