I found this through Firebug:
You are very helpful. Thanks, again.
No problem. Glad to be able to help! :)
I have noticed that although the ads are vertically aligned in IE, Firefox, and Safari...in Opera there is still a 3 pixel space under the ads which pushes the main center div down 9px(3px times 3 ads).
Here is the link: http://nanoweather.com/zebra_photos.html
The problem DIVs are named "adspace". The "vertical-align: bottom" for the java-script related ins worked in every browser I tried
except Opera. I've tried different vertical-align values to see if they had an effect in Opera but to no avail.
