CSS: auto height on containing div, 100% height on background div inside containing div

Question

The problem, is that I have a content div which stretches its container height-wise (container and content div have auto height).

I want the background container,

Answer 1

I ended up making 2 display:table;

#container-tv { /* Tiled background */
    display:table;
    width:100%;
    background-image: url(images/back.jpg);
    background-repeat: repeat;  
}
#container-body-background { /* center column but not 100% width */ 
    display:table;
    margin:0 auto;
    background-image:url(images/middle-back.png);
    background-repeat: repeat-y;

}

This made it have a tiled background image with a background image in the middle as a column. It stretches to 100% height of page not just 100% of browser window size
