In addition, what sticky wants to do is to make this effect JavaScript-free, so that it could be smoothly rendered. If you want to use JavaScript, you can just go back and listen on scroll event and do everything you like there. Using sticky with those two events wouldn't make anything better than just using scroll event, I suppose. - Xidorn
