title: Youtube Videos playing simultaneously even when modal window is closed (Wordpress)
body: <p>In my client website, when we play youtube videos in modal windows, they keep playing as we close the window.</p>
  <p>Site: <a href="https://apoloi9.com.br" rel="nofollow noreferrer">https://apoloi9.com.br</a>. <br>Each of the html list elements, where the videos and names are organized (as shown in the picture bellow), have unique id, but I couldn't find a way to make it work.</p>
