I have a WordPress generated page where I want to place AdSense below the header of the page. See image at http://imgur.com/WPXeG
I want to create some white space
Your #access
div has float:left;
on it, so you will need to add clear:left
(or clear:both
) on the div containing the ad, so they don't overlap.
If you look at your page with Firebug, or the developer tools in your favorite browser, you can see that your ad div actually sits above and layered below your header divs, and when you add clear: both
, it will move down to where it should be.
