Hii,
When we talk about adding animation effect in our web page then  css is one the best option we use along with any of the programming laungage such as javascript,jQuery etc to give dynamic animation effects.
Using animation effect in a webpage helps us to make the web page attractive and beautiful.
Here's is an example of an animation effect using jQuery in which i have created an infinite animation effect which will start as the page will load and stop only if you close that webpage.

Syntax:

1. animate(properties[, duration][, easing][, callback])
2. animate(properties[, options])

Example: 

CSS:

.boxOne{width:500px;height: 500px;display: block;position: relative;border: 1px solid black;margin: 20px auto;}
.boxTwo{display: block;width: 20px;height: 20px;position: absolute;background-color: #2196F3;border-radius:100%;}

HTML:

<div class="boxOne">
   <div class="boxTwo"></div>
   </div>

jQuery:

(function animation() {
   		var options = {
	      duration: 500,
	      easing: 'linear'
   };

   $('.boxOne')
      .find('.boxTwo')
      .animate({
            left: 500,
            top: 480
         },
         options
      )
      .animate({
            left: 0,
         },
         options
      )
      .animate({
            left: 480,
            top: 0,
         },
         options
      )
      .animate({
            left: 0,
         },
         $.extend(true, {}, options, {
            complete: function() {
               animation();
            }
         })
      );
})();
