        In this demo I worked out how to leverage just the YouTube video’s unique ID, and pass it in to a reusable modal component that takes advantage of YouTube’s embed&nbsp;method.

      <h2>
        Note
      </h2>

      <p>
        Auto-play is disabled for certain interaction paradigms, and on certain OS's—Like most touch screen devices that are behaving according to spec. The trade-off here is the user will need to tap the play button once the modal pops on touch-screen devices like iPhones. Depending on your use-case and project that trade-off is likely acceptable.

YouTube Video Modal

I worked out a way to use just a YouTube video's ID in the main page's markup, so it can be passed in to a YouTube video modal / overlay template when a link or thumbnail is clicked. The video modal maintains its 16:9 aspect ratio no matter what the viewport size is, making it properly responsive.
