On my site I placed an Adsense ad block in a text widget and then used this div to reposition it to the top of the content.
ad
I've run into a problem now and I suspect it's because of my code.
If you go here http://source-pro.org/olympus-om-d-e-m5-review/ and scroll over either of the buttons below the Adsense ad you'll see that the buttons are clickable only about 50% of the way up. It is as though my code is causing my ad area to overlay the upper part of my content, and in this case the buttons are only partially clickable.
