I think this is really simple, but I've never really had to do it. I have a website set up in ASP.Net (C# code behind) using a master page, etc. I have the layout/colors/menus etc all laid out nicely. Now all I want to do is add the word Testing or Development to the background, preferably something small that repeats. That way when a user logs on they will know which system they are on at all times. I don't want it to take over the current background colors or scheme. I've tried using some images but the results have been poor. Any suggestions?
