The Header Layout Injector allows you to inject custom Divi Library items before or after the navigation.
After the custom layout is created and saved into the Divi Library, you can set it to display on the homepage, or any other specific pages.
To select layouts go to Divi → Divi Pixel → Layout Injector.
The Blog Injector allows you to inject custom Divi layouts saved in the Divi Library on blog pages. You can inject layouts after the navigation on single blog posts, archive pages, category pages, and search results pages.
Blog Layouts can be injected in Divi → Divi Pixel → Layout Injector.
