Which is the CSS template for the background image?

Which CCS template has the code for the forum's background image? I want to change it from "scroll" to "fixed."

Thanks.

Hello,

Go to: Administration Panel > Display > Colors (under 'Pictures and Colors' in left column) > Click on the 'CSS Stylesheet' tab. The code for the background should be located near the top.

It should look something like this:

Code:

body {
   background-color: #252525;
background-image: url('http://i261.photobucket.com/albums/bg3.jpg');

background-repeat: repeat-x;
margin-top:150px;   
        background-attachment: fixed;
   font-family: Verdana,Arial,Helvetica,sans-serif;   
   font-size: 62.5%; /* This sets the default font size to be equivalent to 10px */
   margin: 0px 0px 0px 0px;
        padding: 0px;
        border-color: #862121;
   border-width: 0px 0px 0px 0px;
   border-style: solid;
}

Thanks, it works. Though I had already adjusted that setting a long time ago. Seems it needed to be done again, for some reason.
