EDIT: Just noticed UW second link shows all this... so never mind.
If you want it to repeat horizontal (but not vertical):
Code:
background-repeat:repeat-x;
FYI, for vertical repeat, change x to y... or maybe I got the two mixed up.
Also, if placement is an issue you can do this:
Code:
background-position:left;
Swap out "left" for any of the following: top,bottom,left,right,center.
