We have two js use first maphilight is map coordinate doing highlights and rwdImageMaps is coordinate resize.
please help!

A:

Seems to be working fine like this: 
(notice the class img-fluid in the image)

$(document).ready(function () {
  $('#myimage').rwdImageMaps();
  var states = [1, 5, 37, 40, 62, 20, 35, 50, 44];
  var area = document.getElementsByTagName('area');
  for (var i = 0; i < area.length; i++) {
    area[i].id = i + 1;
  }
  $.each(states, function (index, value) {
    var data = $('#' + value).mouseout().data('maphilight') || {};
    data.alwaysOn = !data.alwaysOn;
    $('#' + value).data('maphilight', data).trigger('alwaysOn.maphilight');
  });
  $('#myimage').maphilight();
  var resizeEvt;
  $(window).on('resize', function () {
    clearTimeout(resizeEvt);
    resizeEvt = setTimeout(function () {
      $('#myimage').maphilight();
    });
  });
});
