title: HTML - Image hover swap to short video
body: <p>I'm trying to a list of images and when the user hover one of the images it swaps to short video.
  Exactly like Youtube. When I hover my mouse over an image, it changes to a short video, and when I move the mouse it stops and return to image.</p>
  <p>How can I achive such thing? What should I use? Can I achive that with Javascript?
  Maybe there is library or package in the open source that I can use?</p>
  <p>I'm lost and I have been searching alot.</p>
