Answer 1

here is a working demo hope it will help I have done some minor changes in your code now it's working.

 $(document).ready(function () { $('.card2').hide(); $(".navbar .nav-link").click(function () { if ($('.card1:visible').length) { $('.card2').show(); $('.card1').hide(); } else { $('.card1').show(); $('.card2').hide(); } }); });

 .hide { display:none; } .Wrap .card img { height: 250px; }
