Apologies if this has already been covered - tried looking for a solution and found nothing.
I currently have an XHTML theme that I am converting into a wordpress theme. I have managed to do it but I have a few problems with a background image on the post side of the site. Basically on my html theme I have three images that when joined create a rounded corner box. I have merged these together to create one image and used this one image as the background in the wordpress theme. Problem is the image is a static size - so when content goes past the image it is not re-sizing (due to the fixed width).
How could I get this image to resize as I add more content?
