title: Aspect ratio of video responding to height is it possible?
body: <p>I've been searching for an answer for this problem for too long but no such luck!</p>
  
  <p>I want to be able to embed a YouTube video, and if the viewport changes either in height or width the video will change in size whilst keeping the correct aspect ratio, is this possible? </p>
  
  <p>I'm aware of other solutions such as fit vid and the padding-bottom method, but none of these recalculate the aspect ratio if the height of the viewport was to change. </p>
  
  <p>Any ideas welcome, js or css...</p>
  
  <p>Thanks! </p>
