title: HTML hidden tags vs JS createElement
body: <p>It is a YouTube iframe and some divs (about 5 or less) which display video data as title, time and a progress bar and a random video section at the bottom. If the video doesn't exists these (title, time and progress) divs should not be displayed and then if the user click in a random video these divs should be displayed again.</p>
  
  <p>So is it faster to <code>generate hidden tags and show them</code> when the button is clicked with JS or do not generate them at all and create using <code>createElement()</code> ? </p>
  
  <p>What are the pros/ cons? And of course which is faster? </p>
  
  <p>And does that <code>delta time</code> really matter?</p>
