Builder Pro uses the same theme logic as the WordPress core. The templates that you create are associated with a Pro Theme. When you switch the theme, all the associated templates will be activated — with just a snap, you can change the entire site’s design completely.
Pro themes can be exported/imported from one site to another. So you can design the theme on your end and migrate it to your client’s site. Take full control of the entire site from head to toe. Design custom templates that define how WordPress should render the header, footer, posts, pages, search, archives, etc. All done visually with Themify Builder, and without any code.
