How to make smooth scrolling to anchor?

Question

JavaScript

I used this jq code:

$('a[href^="#"]').click(function(){
        var target = $(this).attr('href');
        $('html, body').animate({
            scrollTop: $(target).offset().top
        }, 500);
    });

In general, it is working, but before each anchor it spins at a different speed, because. for everything about everything 0.5 sec, if someone has improved analogs, please share, I want what would happen like on this site:

Answer 1

school mathematics course. S = v * t
you need the same speed (v), so you need to select the correct time (t, which you will enter into the animate function) depending on the path (S).
in total we get the formula t = S/v;
so you are looking for a path from the current scrollTop to the offset().top of your element - this will be (S).
well, you already select the speed by poking.

If in Jquery, then something like this

$('a[href*="#"]').click(function(e) {
  const $target = $(this.hash);
  const topOffset = 100;
  if ($target.length) {
    e.preventDefault();
    $("html, body")
      .stop()
      .animate(
        {
          scrollTop: $target.offset().top - topOffset
        },
        900,
        "swing",
        function() {
          history.pushState(
            {},
            document.title,
            window.location.pathname + target
          );
          return false;
          // window.location.hash = target;
        }
      );
  }
});

It may be enough for you to get by with CSS (scroll-snap property set) if browser support suits. A few articles on the topic:
