WordPress uses pages and posts for the main content of your site. Each page/post creates a place where visitors can go on your site. But ProPhoto layouts provide the look, layout, and extra module content for the pages of your site.
Layouts are assigned to pages in the Visual Builder. Enter the Visual Builder from the front end on any page of your site and click on “Layouts.”
Layouts lists all the layouts you have created and the pages and page types to which they have been assigned. This is where all layout assignments are managed.
