I am trying to place a background image in the contentMainWrapper area so it shows up in the left, center and right columns.

I am using this code:
#contentMainWrapper {
padding-bottom: 20px;
border-left:1px solid #663300;
border-right:1px solid #663300;
background-image:url(../images/Bgmain.gif);
background-repeat:repeat-x;
background-position: bottom left;
}


Opera shows this:

#contentMainWrapper {
background-color: #f3f1f1;
border-left-color: #663300;
border-left-style: solid;
border-left-width: 1px;
border-right-color: #663300;
border-right-style: solid;
border-right-width: 1px;
padding-bottom: 20px;
}

I can't seem to figure out why it is ignoring the background-image line.

TIA Tom
