I use CSS to position my Google AdSense ads when the web page loads. I recently noticed that my footer Google AdSense ad sometimes covers my right-side navigational links such as on http://www.romancestuck.com/test-pages/35th-anniversary.htm
The ad is sometimes a smaller width than other times. So, you may need to refresh the page a couple times to see the wider ad that overlaps the navigational links.
Anybody know how to set up this ad CSS positioning so that is always below the main content or the right-side navigational links, whichever is longer?
