How to stop background gradients repeating?

[Bacon Butty]

I've done searches for solutions and all of them haven't worked.

So far, (from the solutions I found from searches) to get this gradient to work, I have tried putting these into the CSS background section in style manager;

#1b4985 url(http://img182.imageshack.us/img182/9868/bgku4.jpg) top left repeat-x
#1b4985 url(http://img182.imageshack.us/img182/9868/bgku4.jpg) repeat-x
#1b4985 url(http://img182.imageshack.us/img182/9868/bgku4.jpg) repeat
url(http://img182.imageshack.us/img182/9868/bgku4.jpg) top left repeat-x

However, the gradient still repeats itself hall way down the page as shown here.

Any help would be greatly appreciated.
