Например

height: auto !important;
    height: 100%;
    margin: 0 auto -6em;
            }
             .push {
    height: 480px;
    float: right;
    width: 480px;
    top-right: 100px;
    right: 10px;
    top:+150px;
    margin-top: 10px,5px,100px,80px;
    margin-right: 10px;
    position: relative;
    top: 150;
    clip: rect(60px,0px,200px,0px);
}
            [B].footer {
    background-color: #171820;
    background-image: url(images/bg_bot.jpg);
    background-repeat:repeat-y;
}
            .wrapper, .footer {
                width:500px;
                height:270px;
                margin:-200px;
                left:20px;
            }[/B]

A:link {text-decoration: underline; color: #94b400}
A:active {text-decoration: underline;}
A:hover {text-decoration: none; color: #94b400}
A:VISITED {text-decoration: underline; color: #94b400}
/* MAIN */
body {
    background-color:#171820;
    font-family:arial, verdana, helvetica, sans-serif;
    font-size:90%;
    color:#94b400;
    text-align:center;

Ну, в данном случае это всего лишь класс, типа
<div class="footer">
