Banner help

right now I have a background image for the team name which goes with each style and then below that a banner that is the same for all teams I think its from the main.tpl or something anyway once I remove the main banner I want to add it back under the team name but use the style.css to call it so each style can have their own images. So this is what I have

:.pun #brdtitle { background: #121C5E }
#brdmenu A:link, #brdmenu A:visited {
   font-weight: bold;
}

#teamname {
    background: url(http://www.d1acollegefootball.com/Forum … linois.gif) center center no-repeat;
    height: 30px;
    margin: 0px;
}

Whats the command to call another image and center it below that one with about 5 pixels padding?

Thanks for any help!
