</div>

Step 2 - Add CSS:

/* Popup window container */
.popup {
  position: relative;
  display: inline-block;
  cursor: pointer;
}
/* Actual popup window (appears at the top) */
.popup .popuptext {
  visibility: hidden;
  width: 160px;
  background-color: #555;
  color: #fff;
  text-align: center;
  border-radius: 6px;
  padding: 8px 0;
  position: absolute;
  z-index: 1;
  bottom: 125%;
  left: 50%;
  margin-left: -80px;
}
/* Popup window arrow */

  content: "";
  position: absolute;
  top: 100%;
  left: 50%;
  margin-left: -5px;
  border-width: 5px;

}
/* Toggle this class when clicking on the popup container (hide and show popup window) */
.popup .show {
  visibility: visible;
  -webkit-animation: fadeIn 1s;
  animation: fadeIn 1s
}
/* Add animation (fade in popup window) */
@-webkit-keyframes fadeIn {
  from {opacity: 0;}
  to {opacity: 1;}
}
@keyframes fadeIn {
  from {opacity: 0;}
  to {opacity:1 ;}
}

Step 3 - Add JavaScript:

<script>

function myFunction() {
  var popup = document.getElementById("myPopup");
  popup.classList.toggle("show");
}
</script>
