[Mediawiki-l] Logo repeating itself

[Ekompute .info]

Hi, I wonder my logo is repeating itself to fill up the space allocated to
it at Webmasterteachyourself.com <http://webmasterteachyourself.com>. When I
write no-repeat as in:

#p-logobar .pBody {
    position: absolute;
        top: 0;
    left: 0;
    padding: 0 0 0 0;
    margin: 0 0 0 0;
        height:4.0em;
        width:100%;
        background: white no-repeat;
}

the logo does not appear.

What do I need to do to set it right?
