Alb full width submenu sticky on mobile

Hi
A few days ago Mike provided me with a function to make sure that using the sticky menu on mobiles and tablets the anchors scroll correctly by adding the additional sticky menu of the ALB.
https://kriesi.at/support/topic/alb-full-width-submenu-sticky-on-mobile/

The code works perfectly but only takes into account two screen sizes: < 989 and >990.
I would need an integration to be able to use it on three different screen sizes: <768 for mobiles < 989 for itablets and >990.
I tried to write it myself but couldn’t do it. I basically can’t write the middle line of code which should be something that looks like else if ((width >768 <990)) {

Below is Mike’s code

function custom_change_offset() { ?>
  <script>
(function($) {
	var width = $(window).width();
    if ((width < 989)) {
  $('a[href*=#]:not([href=#])').click(function() {
    if (location.pathname.replace(/^\//,'') == this.pathname.replace(/^\//,'') 
&& location.hostname == this.hostname) {

      var target = $(this.hash);
      target = target.length ? target : $('[name=' + this.hash.slice(1) +']');
      if (target.length) {
        $('html,body').animate({
          scrollTop: target.offset().top - 140 //offset
        }, 1000);
        return false;
      }
    }
  });
  //Executed on page load with URL containing an anchor tag.
  if($(location.href.split("#")[1])) {
      var target = $('#'+location.href.split("#")[1]);
      if (target.length) {
        $('html,body').animate({
          scrollTop: target.offset().top - 140 //offset
        }, 1000);
        return false;
      }
    }
    } 
    else if ((width > 990)) {
  $('a[href*=#]:not([href=#])').click(function() {
    if (location.pathname.replace(/^\//,'') == this.pathname.replace(/^\//,'') 
&& location.hostname == this.hostname) {

      var target = $(this.hash);
      target = target.length ? target : $('[name=' + this.hash.slice(1) +']');
      if (target.length) {
        $('html,body').animate({
          scrollTop: target.offset().top - 150 //offset
        }, 1000);
        return false;
      }
    }
  });
  //Executed on page load with URL containing an anchor tag.
  if($(location.href.split("#")[1])) {
  	var targett = $('#'+location.href.split("#")[1]);
      if (targett.length) {
        $('html,body').animate({
          scrollTop: targett.offset().top - 150 //offset
        }, 1000);
        return false;
      }
    }
    }
}(jQuery));
</script>
  <?php
}
add_action( 'wp_footer', 'custom_change_offset', 99 );
