title: video with 100% width on a widescreen
body: <p>When I set my html5 video width and height to 100%, the video height is bigger than the browser visible area and a vertical scrollbar appears. </p>
  
  <p>Is it because my video is in 4:3 format? How can I resize it to fill the entire space without having to scroll down the page?</p>
  
  <p>Thanks for reading!</p>
