CSS Html expanding length image repeat

I have a web page with the css set to have a background image fill the screen

body {
	line-height: 1;
	color: black;
	background: white;
	background-image: url("../img/tdb/wood-54.jpg");	
	background-position: top;
	background-repeat: repeat-x;
	background-color: #e8e3D0;
	font-family: Georgia, serif;
}

Select allOpen in new window

I then have css (.content) to have another centered H1 which has in image applied to it that stays centered at all times. There are tables and other content within this.

.content {
	width: 980px;
	margin: 0 auto;
}

.content h1 {
	background-image: url(../img/tdb/clip-paper.png);
	background-repeat: no-repeat;
	background-position: center top;
	width: 960px;
	height: 920px;
}

Select allOpen in new window

This all works fine. The image is a book and I can put content "on the page" so it looks as we want. The trouble is when the content is longer than the book. Width is not an issue as I have it set at 960px. I have made the book so that there is a top and bottom image and I now have a centre image that can be repeated as necessary to stretch the book while retaining its width.

I do not know what design to use to make this happen. Tips?

Thanks and sorry for the extended babble.

Cheers
