I'd like to make sure I'm examining one of the listings that had a background before revise edit dropped it. If I'm correct the code I removed should be missing from those, i.e. rejected by the editor.
What's a good listing number to look at that is similar to the one you initially posted on this threat?
The area in eBay where you customize Store page is also where I believe you can customize use of the Search and Category appearing on a listing page. It was that feature I was looking for, to see if the background could be tied to that instead of the entire page.
I'm peeling the onion, as there are layers within layers of code here to examine.
