title: Absolute Iframe URL issue
body: <p>I will admit I'm very unfamiliar with html - I've only really worked with object-oriented programming and not markup languages.</p>
  <p>I'm working on audio controls for a website for someone else, I feel like I understand how the control tag itself works, but I cannot make the urls I link or function in audio players. I think it's the because of how I'm uploading the files, but I don't know if a website directly uploads the files. (I've tried using dropbox/google drive, but I don't think I can get the link I would need for that.)
  Because of requests from the employer I'm working through go-daddy's iframe and not creating from scratch if that is relevant.</p>
  <p>The upper line is my attempt at writing audio controls, the second controls are just an example I've been trying to mimic.</p>
