Solution 1:

Try using the css classes that you have provided, and pass a second parameter to the "addClass" call indicating the number of milliseconds that it should animate. For example:

$(".trigger").hover(function(){
    var $this = $(this);
    $this.next(".overlay").addClass("fadeInDown", 1000);
}); 

Solution 2:

Add following css and HTML tag .

HTML code:-

<h1class="animated fadeInUp" >Example</h1>

CSS code:-

.animated {
  -webkit-animation-duration: 1s;
  animation-duration: 1s;
  -webkit-animation-fill-mode: both;
  animation-fill-mode: both;
}
@keyframes fadeInUp {
  from {
    opacity: 0;
    -webkit-transform: translate3d(0, 100%, 0);
    transform: translate3d(0, 100%, 0);
  }

  to {
    opacity: 1;
    -webkit-transform: none;
    transform: none;
  }
}

.fadeInUp {
  -webkit-animation-name: fadeInUp;
  animation-name: fadeInUp;
}
