css gradient with image strip height issue

Question

How could I use my linear-gradient pattern strip,mystrip.jpg (1x1024 px), to be the body background of my web page? I need to repeat itself horizontally and have its height 100% of the body height.

I tried with

body{background:url(mystrip.jpg) repeat-x;} 

but whenever my body content is exceding 1024px height,I can see clearly the bottom border of my strip pattern.

Thanks

Luca
