Hello, I thought this was a very simple problem. I’m trying to set the various pages of a site with individual background themes. I want the users to define pick their own them color or image which would be stored in a database, and then dynamically applied via Ajax during runtime. To test the concept, I started off with this simple script which should set the background color of every page to white, except for 3 pages which I expect to retain the default background theme as defined in my css file(Default is a color gradient). Unfortunately, these 3 pages also displayed a white bg, and not the default gradient theme. Any ideas why? Here is the code.
