Scroll to a certain height slowly

Question

Im doing this to scroll to a certain position:

window.scrollTo(0, scrollPos);

But it jumps up immediately. How do I make it scroll slowly?

I tried:

$('body').animate({
  scrollTo: scrollPos,
 }, 1500);

but still jumps up

Answer 1

The property you want is scrollTop

$('body').animate({
  scrollTop: scrollPos,
 }, 1500);
