I cannot for the life of me figure out why this technique will not display correctly on my hosted site.

It works fine in the fiddle below as well as locally on my laptop when accessing index.html from a browser.

However, when I upload to the test site and test this snippet in the latest versions of Safari, Opera, Chrome and FF it displays nothing.

I'm at a loss. The solution is definitely not obvious to me. I can provide the site URL if needed.
