Asking because it seems like the "fixed" code section almost seems important to the responsive aspect, although perhaps that was a fix posted in the forum for the template, I don't know. I also don't know how the fix was discovered, trial and error/educated guess or documented elsewhere.
There are three css files in responsive_classic/css/ and three css files in template_default/css/. I opened the "larger image" window on my old site and compared that code to the "larger image" window on my soon-to-be site and the only difference was that bit of code. I had sent a couple of emails to the person who made the template, through their website and a PM through the ZC forum with no response. I've spent a lot of time on this one annoying issue, and the larger image popup is important so that my customers can see a better version of the item they're interested in buying. So, it was trial and error and educated guess and comparison between installations and lots of complaining to my husband who was tired of hearing about it. :) I've had a bunch of customers test out the new site and haven't heard any other complaints, so I'm going to call it good and go on with my life unless I hear something different later. :)
