  $('a[href*=\\#]:not([href=\\#])').click(function smoothScrollToId() {
    if (window.location.pathname.replace(/^\//, '') === this.pathname.replace(/^\//, '') && window.location.hostname === this.hostname) {
      let target = $(this.hash);
      target = target.length ? target : $(`[name=${this.hash.slice(1)}]`);
      if (target.length) {
        $('html,body').animate({
          scrollTop: target.offset().top - 75 // extra 75px to avoid the height of sticky navbar
        }, 500);
        return false;
      }
    }
  });

 $('.back-top').click(() => {
    const body = $('html, body');
    body.stop().animate({ scrollTop: 0 }, 500);
  });
