Hi there,

I am looking to get some advice on adding images (banners) to my website on the home page, I currently have main content which is centered which leaves a space on the left hand side and a space on the right hand side.

I wish to add some ad banners in these spaces, I have tried adding some text to see if I can get it to go to the far left of the main content but it will only line up to where the main content text starts.

Do I need to add more to the css stylesheet so I can add the banner images to the left and right.

This is the current css I have;


HTML Code:
@charset "UTF-8";

	margin:0;
}
body, html  {
	height:100%;

	font-family: Arial, Helvetica, sans-serif;
}
#wrapper {

	list-style-type: circle;
	padding-left: 15px;
}
#contact_copy  h4 {
	line-height: 1;
	padding: 10px 0;
}

Also if I add a new css value do I have to add a link here on my index.html


HTML Code:
  	</script>
<link href="css/PCstyles.css" rel="stylesheet" type="text/css" />
<link href="css/PCcopy.css" rel="stylesheet" type="text/css" />
<link href="css/box.css" rel="stylesheet" type="text/css" />
<link href="css/glossytabs.css" rel="stylesheet" type="text/css" />
</head>
<body>
<div id="wrapper">
   <div id="header">
