Applying a css "fade out" transition animation upon clicking a link before traveling to the next page.

fadeout.css

/* fadeOut animation css */
.fadeOut {
  animation-name: fadeOut;
  -webkit-animation-name: fadeOut; 

  animation-duration: 0.4s; 
  -webkit-animation-duration: 0.4s;

  animation-timing-function: ease-in-out; 
  -webkit-animation-timing-function: ease-in-out;   

  visibility: visible !important; 
}
@keyframes fadeOut {
  0% {
    transform: scale(1);
    opacity: 1.0;
  }
  100% {
    transform: scale(0);
    opacity: 0.0; 
  }
}
@-webkit-keyframes fadeOut {
  0% {
    -webkit-transform: scale(1);
    opacity: 1; 
  }
  100% {
    -webkit-transform: scale(0);
    opacity: 0.0;
  }
}

fadeout.js

$('#navPills').find('a').click(function (e) {
  var t    = this,
  
      //store the href for the clicked element
      href = t.href;
      
  //prevent the default behavior
  e.preventDefault();
  
  //apply the fade out transition class to the parent ul element
  $(t).parent().parent().addClass('fadeOut');

  //setTimeout to wait for fade out animation to complete before changing pages
  setTimeout(function (){
    window.location = href;
  }, 200); //the length of time should vary depending on the length of the animation.
});
