Got it! Thank you so much for your help. I had added the css snippet before. I removed it and with your help identifying the original code in the video I was able to search it, find it and I changed the #FDFCFC to #transparent. That did the trick.
I’ve been fooled by the cache before so I know what you’re talking about. Cleared it and site appears the same in Firefox and Safari. Also no cache plugins.
