Remove Header Margin

Unless you provide a link to a page demonstrating the problem, no one will be able to offer much in the way of assistance.

Edit sty;le.css and change:

#title.aligncenter {
    margin: 20px auto 0;
    text-align: center;
}
#footer {
    background: url("images/line.png") repeat-x center top;
    clear: both;
    float: left;
    font-size: 11px;
    line-height: 13px;
    margin: 10px 2% 0;
    padding: 20px 0;
    position: relative;
    text-align: center;
    width: 96%;
}

to:

#title.aligncenter {
    margin: 0 auto;
    text-align: center;
}#footer {
    background: url("images/line.png") repeat-x center top;
    clear: both;
