I created this script a while ago and recently updated it to utilize css sprites in order to reduce the number of images. While everything functions perfectly in ie9 and ff4, I have discovered that it fails to display properly in ie7/ie8... This issue seems to be related to either css or js, but after careful inspection, I am unable to identify any reasons why the older versions of Internet Explorer are not rendering the code...
I have included the complete contents below on a 'test' page that contains all the elements... If anyone can assist me in pinpointing why this isn't working in ie7 or ie8, I would greatly appreciate it!
