title: How to make Youtube video responsive for mobile but NOT fullscreen on desktop
body: <p>Apologies if this has been asked before, I found similar but not exactly what I'm looking for.</p>
  <p>I've found various online tools to embed a responsive Youtube video, however in doing so, it makes them huge on desktop (as it's set to 100% I think and taking up the whole screen).</p>
  <p>I found a piece of code that apparently fixes this problem here <a href="https://forum.freecodecamp.org/t/help-resizing-embed-youtube-video-with-css/210568" rel="nofollow noreferrer">https://forum.freecodecamp.org/t/help-resizing-embed-youtube-video-with-css/210568</a> but am unsure where that code fits into what I have so far (i'm a complete novice with code).</p>
  <p>Would someone be able to help and provide me with the full piece of code I will need (I only have access to the HTML), so that I can just slot in the youtube link?)</p>
  <p>Thanks in advance!</p>
