Click on Menu Navigation animate to that Section

Question

I have a menu, when I clicked on each nav, it used to animate to resume on that specific section.

Somehow, now it didn't do that anymore recently.

What should I check? I see nothing in my console.

I used JS

This is the snippet

$('#main-menu').onePageNav({
    currentClass: "active",
    changeHash: false,
    scrollThreshold: 0.5,
    scrollSpeed: 750,
    filter: "",
    easing: "swing"
});

Answer 1

You only need to add this one line of code.

$('html').css("scroll-behavior", "smooth");

Answer 2

if you were using css then you're missing this line scroll-behavior: smooth;

and if u were using js then please provide a snippet :) thanks for your collaboration.
