Hi jcreep we would never ignore newcomers..
Ok that's not quite what I meant, I was looking for the CSS ID for the page.. the quickest way to find it is to view the source of the page.. then just after all the <head> code.. you're looking for
<body id="?" class="maybe some classes too">
if you can find that line and post it, I (or someone) should be able to tell you if there's a unique Identifier in there.
the post itself usually has a unique identifier, but it might be that this banner div you want removed is not inside that identifier, so I'm looking to see if there is an ID or Class on the <body> element which is related to the WP postID too.. that would be unique and is often what is built into WordPress and other CMS's.. I'm hoping ;)
alternatively you could post the HTML (from view source, not the Wordpress php code) from the opening
<body ... to where the banner closes </div>
as this may offer a way to target it
if you find that you then just put in your CSS:
#theuniqueID #thebannerDiv {display: none;}
the solution is simple it's finding the combination for the selector..
