Hey,
You need to do exactly the same what you did on video from post above, just use code below instead, and you need to set class on that button “scroll-to-top”.
let isScrolling;
$(window).on('scroll', function() {
if (isScrolling) {
clearTimeout(isScrolling);
}
// Show the button while scrolling
$('.scroll-to-top').css("opacity", "1");
$('.scroll-to-top').css("pointer-events", "auto");
// Set a timer to hide the button after 300ms of no scrolling
isScrolling = setTimeout(function() {
$('.scroll-to-top').css("opacity", "0");
$('.scroll-to-top').css("pointer-events", "none");
}, 300);
});
