Animation for background image

Hey all, I am fairly new to web dev and Webflow but I am trying to get a background image to move on the X & Y axis slightly on mouse hover. I want the background image to be behind the nav bar and all content and have achieved this by setting the position as absolute but I suspect this is stopping the animation. Any help would be much appreciated.
