And add the following code into it,may be in the last line.Replace the height: 80px; width: 411px; background: url(images/logo.gif) by your banner details and location.

.custom #header #logo a { display: block; height: 80px; width: 411px; background: url(images/logo.gif) no-repeat; outline: none; }
