 });

 $("#breathe").on("click", function() {

  $('.heart-car').hide();
  $('.sleep-car').hide();
  $('.breathe-car').show();
  $('.sport-car').hide();
 });
 $("#sport").on("click", function() {

  $('.heart-car').hide();
  $('.sleep-car').hide();
  $('.breathe-car').hide();
  $('.sport-car').show();

 });
 $("#sleep").on("click", function() {

  $('.heart-car').hide();
  $('.sleep-car').show();
  $('.breathe-car').hide();
  $('.sport-car').hide();

 });
