Header Transparency

I’ve been looking around, but I have been unable to find a solution for this. It’s not really a problem, but just something I would like to implement to stylize my website a little more. I have a PNG image with the background set to be transparent, but it still comes up white. Is there a way I can work around this, or implement something through CSS?

EDIT: Figured it out with this in my CSS

“
#page {
background:transparent;
}
#main,#primary {
background:#FFF;
}
#access {
margin-bottom:0;
}
”
