Philosophical debate

Time for a philosophical question. If you are viewing a web page with an animated gif does the gif continue to animate after you have scrolled away from that part of the page? We could consider whether a browser renders an entire page and keep it in memory or just the part being viewed and thus if it is rendered in memory are changes to that page maintained in memory or actioned only when viewed? Or we could consider the question from a philosophical point of view, perhaps a kind of Zen web design. Does a gif animate if no one is around to see it? Does the gif animate or is everything else animating and the gif is constant.

For that matter does a web page exist if no one ever visits it?
