Can play bass... not so much on the html/css

My band has an all flash site, and I've just started putting together a non-flash/mobile-ish site. I use templates, I'm just smart enough to research, problem solve and tweak things to make it look like I want it... barely. Now I'm stuck...

The mobile site is at www.arisenfromnothing.com/afn.html

I can't figure out how to change the orange vertical lines in the lower div's

The stylesheet in question (I think) is this:

/* reset */
* {
margin: 0;
padding: 0;
}

/* render html5 elements as block */
header, footer, section, aside, nav, article {
display: block;
}

body {
line-height: 1;
background: #ddd url("bg.gif") repeat;
font-family: Verdana, Arial, Helvetica, sans-serif;
color: #ddd;
font-size: 14px;
line-height: 18px;
}

/* layout */

#wrapper {
position: relative;
width: 940px;
margin: 0 auto;
margin-top: 5px;
margin-bottom: 2px;
-webkit-box-shadow: 3px 3px 7px #111;
-moz-box-shadow: 3px 3px 7px #777;
}

nav {
width: 940px;
height: 50px;
margin: 1px;
background: #000;
}

header {
width: 940px;
height: 900px;
margin: 2px;;
background: #fff url(inwt.jpg) no-repeat left top;
}

#main {

margin: 0 auto;
padding-top: 30px;
background: #111 url(colbg1.png) repeat-y;
overflow: hidden;
}

#content {

Any help would be appreciated

The vertical lines are in the background image: http://www.arisenfromnothing.com/colbg1.png. So you need to edit the image to change that.
