Horizontal Form script makes mobile form not working

Hi guys,
I used the script to have horizontal forms on landing page -> https://landing.filotrack.com/hype-it-filo-2-0-visitatori-sito/

This is the script I used (I had to remove closed tags “< >” from “script” because the script didn’t show in my question)

<script>
/**
    * Do not remove this section; it allows our team to troubleshoot and track feature adoption. 
    * TS:0002-08-042
*/
  lp.jQuery(document).ready(function($) {
    
    //Change #lp-pom-box-01, etc. for the IDs of the boxes where you want the form fields to display.
    var boxes = ["#lp-pom-box-50",
                 "#lp-pom-box-51"];
    
    $('.lp-pom-form .lp-pom-form-field')
      .each(function(i, field) {
        $(field)
          .offset($(boxes[i]).offset())
          $(this).children().width($(boxes[i]).width()-16)
      });    
  });
</script>

Now I don’t need to have horizontal forms on mobile devices and I would like to have just the normal form on mobile version of the landing page.

The problem is that I cannot find out how to do that and I can’t make the form working on mobile version.

Can you help me?
