I am using Drupal 7.
I want to make different looking pages, but I can't do this because it is always using the main theme block regions, and I can't change my specific page elements. For example, I want to make a page that has a cartoon images and another page that has a movie images on the background, and the block regions can be reordered. I tried Pages in Structure menu, but I don't understand it. I created one page, and assigned it a URL, but I can't access the page with my URL, as it says "page not found."
