To add a smooth scroll for anchor links

LeadPages Smooth Scroll

<!-- Smooth Scroll -->
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
<script>
$(document).ready(function(){
  // Add smooth scrolling to all links
  $("a").on('click', function(event) {

      // Make sure this.hash has a value before overriding default behavior
    if (this.hash !== "learn") {
      // Prevent default anchor click behavior
      event.preventDefault();

      // Store hash
      var hash = this.hash;

      // Using jQuery's animate() method to add smooth page scroll
      // The optional number (800) specifies the number of milliseconds it takes to scroll to the specified area
      $('html, body').animate({
        scrollTop: $(hash).offset().top
      }, 800, function(){
   
        // Add hash (#) to URL when done scrolling (default click behavior)
        window.location.hash = hash;
      });
    } // End if
  });
});
</script>

<!-- This is the code for your anchor where you want people to land. Quick and easy. Do not paste with code above -->
<a name="learn"></a>

<!-- This is the code for your anchor if you want smooth scrolling. Do not paste with code above -->
<div class="main" id="learn">

Simple concept for reference:

$("a").on('click', function(event) {
  const a = this;
  const { hash } = a;
  
  event.preventDefault();

  // ... Animation and other handling.

  window.location.hash = hash;
})
