I am beginner in web development and I'm having trouble wrapping my head around this problem.
I have taken a video and encoded it into an mp4 file and an ism file. I have two different video tags- one that will play each file. For the website I'm working on I would like it to use one of the video tags if the website is being viewed on a mobile device, and the other if it is not. Right now the website is in HTML5. Thank you for any help you can give!
