Now you can adjust the Design options in that page if you want the page to have special or different design that is different from the default settings in the customizer. In the customizer the settings can be set globally for all the theme elements in pages and posts. In Rt-Theme 19 the ability has been added to alter these global settings for a individual page or post. Each page or post has a section called “Design Options” with a lot of settings that can be changed for that page or post only. It gives one the ability to have a completely different look for one page or post as you can alter the background image for the body, left menu area or right side content area, a background color etc.
