When I build a website, I mainly design with 800x600 and 1024x768 in mind. Right now I'm building a whimsical style site where the background is just a diagonal shape, with a straight rectangular shape over that, 800 pixels wide. There's no problem on web pages that is simply 800x600, like the main or contact page, but for pages with more content where the screen may need to scroll vertically a little, I'm having trouble because I don't want the background image to overlap. Do I just need to create a new background image for each page, according to how long it needs to scroll?
