Logo background

I have my own logo and do not want to use the given one in the template. I want to replace it with my own. When I do so, I still have the ribbon in the background. How do I get rid of that and just use my own logo?

In template_css.css:

.mp_logo {
background: url(../images/custom/logo_bg.png) no-repeat center;
height: 159px;
}

remove line:

background: url(../images/custom/logo_bg.png) no-repeat center;

Thanks a lot. I was able to do the same. Many many thanks.
