Thanks a lot, this is very helpful!

Hi all,

I want my web site to look like this NYC Auto Show site:

https://www.autoshowny.com/

Notice that the header and the full-screen video below it occupy 100% of the screen height, and there are sections below that as well. 

What HTML5/CSS3 code should I use to achieve that effect? I tried header {height: 10%}  .videosection {height: 90%} while setting the video width and height to 100%, but that did not work.

Thanks in advance!
