With Divi, even blogs are a module, and your “blog” can be placed anywhere on your website, and in various formats. You can combine blog and sidebar modules to create classic blog designs. 1 column, 2 column or 3 column blogs can all be built using blog and sidebar modules.
Before you can add a blog module to your page, you will first need to jump into the Divi Builder. Once the Divi Theme has been installed on your website, you will notice a Use Divi Builder button above the post editor every time you are building a new page. Clicking this button will enable the Divi Builder, giving you access to all of the Divi Builder’s modules. Next, click the Use Visual Builder button to launch the builder in Visual Mode. You can also click the Use Visual Builder button when browsing your website on the front end if you are logged in to your WordPress Dashboard.
