I have site http://www.d1210091-6206.cp.blacknight.com/site/home/ having alignement issue for zoom in & out for the particular section (News & fb ) div id footerwrapper on the page. All other are aligned centerly on zoom in & out.
I am sending you the screen shot also. http://screencast.com/t/e95jEwR6dki
I check your code, if you touch the file style.css, the style for the element #footer, and if you don't use
float: left; margin-left: 210px; width: 600px
Erase it, the div#footer will be centered. But at all the facebook section, you will find it with a little crop on the top. You can leave some margin or padding for that.
In a temporary Backup old shool method, you can use the tag (not recommended if you want to change the styles more freely), with two columns and width specified width for each one.
Greetings
You have to delete "margin-left: 210px" from #footer. It overwrites the "margin: 0 auto;" from .container-12 class.
I would suggest use of bootstrap, like this it was helpful to me..
