title: What variable/attribute changes when you hit play on an HTML5 video controller?
body: <p>I'm using HTML5 video tags in my webpage. I have a small "Watch Video" button that opens a modal displaying this video. Everything works as intended. I am, however, trying to determine what changes in the HTML document (or possibly the DOM?) when I hit the controller's play button.</p>
  
  <p>The goal in determining this is to have the video begin playing automatically once the modal is revealed which I plan to do with a small JS script. Also, when I close the modal window, I will have it disappear.</p>
  
  <p>I did a few Google searches and started to see people discussing creating custom controllers for these videos which I feel is unnecessary - I want to utilize/modify what is already in existence.</p>
  
  <p>To summarize: What is happening when I hit the play/pause controllers in an HTML5 video?</p>
