(hopefully this is posted to the right section of the forum.)

i've tried searching online for simple solutions to my problem but i suspect my search terms aren't correct as i can't seem to find anything related.

the problem is that i wish to create a page that has continuous borders running down either side of the page - very similar to what you see at
http://www.blogger.com/start.

here's an image to hopefully explain further what i mean.

whenever i try to implement this, the image i'm using either doesn't tile and repeat itself enough times (in any browser) or i get a margin at the bottom even though it is set to zero.

i can knock up a page or two to demonstrate further but as they will be so rudimentary i don't think they will help a great deal.

thanks for any help - if it's something that only an advanced html/css coder could implement then i'm prepared to put the effort in to learn.

thanks in advance.
