A client with a website that has a home page that is a fullscreen image, asks me to put a gif on it. He has a crocodile that represents a virus and the eyes of this animal open and close. I put an example capture to show what I would like to do. And this gif has to be fixed so that if you visit this website with a mobile screen it does not move, it does not matter if it is hidden.
Use
position: fixed
( documentation ) in the css of thediv
one containing the gif:Where X and Y is the position (X,Y) on the screen.
