I had received help with a similar issue earlier and when I first tinkered with it everything came out perfectly. I then tried moving something around and now no matter what I do I can't get the thing to center, resize, and set proper background colors.

The current code is:

<style type="text/css">
body {padding: 0; margin: 0;}
#logo   {
               padding-top: 50px;
position: fixed;
               background-color: #000000;
               width: 100%;
               height: 182;
               z-index:98;
               }
.img    {
display: block;
                width: 952px;
height: 182px; 
                margin-left: auto;
                margin-right: auto;
margin: auto; 
z-index: 100;
background-color: #FFFFFF;
}
</style>
<div id="logo">
<img src="http://bpbuild.concrete5.arvixe.com/files/6313/7156/5959/Logo.png"/>
</div>

and the url ishttp://bmpbuild.com/concrete
