hello. I'm experiencing problems with my css code (once again) working with Firefox and not working with IE 6 or 7

I have a problem with my head_logo_inner not too sure what's going on . Here is my css for this particular template.
Code:
body{
	background-color: #333333;
	color: #333333;
	margin: 0px;
	padding: 0px;
	font-size: 0.8em;
	font-family: Verdana, sans-serif;
}
