title: How I can mute audio from iframe?
body: <p>I'm creating a tribute page (for freecodecamp.com) about Elon Musk and I wanted to include his game into my page via  attribute. Is it possible to mute the autoplay audio? My page url: <a href="https://codepen.io/auginis/full/BdwBZW/" rel="nofollow noreferrer">https://codepen.io/auginis/full/BdwBZW/</a>
  The game: <a href="https://blastar-1984.appspot.com/" rel="nofollow noreferrer">https://blastar-1984.appspot.com/</a>
  Here is the code for it: </p>
  
  <pre><code>&lt;iframe src="https://blastar-1984.appspot.com/" width="1000px" height="1000px"&gt;
    &lt;p&gt;Sorry, your browser does not support this game&lt;/p&gt;
  &lt;/iframe&gt;
