Ah the preview showed the html so I thought it would work.

Thank you so much!! Data URLs were exactly what I was looking for with a little modification! Apparently chrome doesn’t allow looping with audio unless it meets certain strict criteria per google. Here is my final URL:

data:text/html,

Lol I can understand what that does. The reason I am asking about JavaScript is that potentially I can use it like a url.

How about JavaScript which writes a simple html page. Any clue how I might go about that?

I know how to do this but I was hoping there was some way to build it into the url.
