FYI, I found that, using just the CSS in this thread, "!important" is not necessary for setting the background-color. However, I guess it might be due to something else in your CSS. Anyways, here is something I think will get you what you want. Remove all the background-image and border-image stuff from the previous attempts. Like your first background-image attempt, this will stretch the image to whatever length the infobox is. If you don't want this then you need to set a fixed height and repeat in the y-direction. You did the latter half in your previous attempt but it was pointless since your height was set to 100%.
