title: HTML5 Video: Are there any benefits to using a source element over the src attribute
body: <p>According the <a href="https://developer.mozilla.org/en-US/docs/Web/HTML/Element/video#attr-src" rel="nofollow">MDN documentation</a> on the HTML5 video element, the <code>src</code> attribute is optional:</p>
  
  <blockquote>
    <p><strong>src:</strong> The URL of the video to embed. This is optional; you may instead use the <code>&lt;source&gt;</code> element within the video block to specify the video to embed.</p>
  </blockquote>
  
  <p>Is there a reason why using the <code>&lt;source&gt;</code> is any better or worse as an approach? Or is it literally just a different way of doing it?</p>
