I have the following script that provides an anchor effect:

// Smooth scrolling when clicking on a hash link
    $('a[href*="#"]').on('click', function (e) {

        var target = this.hash;
        var $target = $(target);

        if ($(window).width() > 1023) {
            var $scrollTop = $target.offset().top - 120;
        } else {
            var $scrollTop = $target.offset().top;

        $('html, body').stop().animate({
            'scrollTop': $scrollTop
        }, 900, 'swing');

The problem is that this only works on home page, but in the other pages it does not work because I need to provide the web link (www.url.com/#anchor). But if I do this, the effect does not apply. someone knows how to add to the effect, for example get_site_url ('/#anchor/'); , and so this always take the url of the web as a base?

I hope I have expressed myself well. Greetings and thanks

CSS now has the property scroll-behavior (browser support is there but not so great). You can use it as described here:

html {
  scroll-behavior: smooth;

@media (prefers-reduced-motion: reduce) {
  html {
    scroll-behavior: auto;

If this doesn't work for you, you're stuck with JS. The problem is, on a new page load, browsers automatically jump to the position of the fragment. But there is a workaround as described in this StackOverflow answer:

// to top right away
if (window.location.hash) scroll(0,0);
// void some browsers issue
setTimeout(function() { scroll(0,0); }, 1);

$(function() {
    // *only* if we have anchor on the url
    if(window.location.hash) {
        // smooth scroll to the anchor id
        $('html, body').animate({
            scrollTop: $(window.location.hash).offset().top + 'px'
        }, 1000, 'swing');

    Wow, The CSS option works perfectly. One more question, is the first time I use an anchor effect and now the problem is that it slides under the title because I have a sticky menu, how could I fix this bug? Thank you

  • @DarioB. You can do this in JS, but there is also a pure CSS way: :target. The WordPress Docs uses this mechanism, just inspect the headline and you'll see padding-top and negative margin-top
