How to add Jquery easing effects | Jquery tutorial

Lets start with the a little introduction, easing refers to the acceleration and declaration that occurs during the course of an animation to give it a more responsive and natural feel. There are two types of easing methods that the core Jquery library supports, which are Linear and Swing lets us see how to implement this easing methods, but before that lets see a brief description on linear and swing easing methods.

Linear easing:
Linear easing method accelerates and deacclereates at a constant rate which makes it look fairly boring but it is good to know the linear easing might comin handy.

Swing easing:
Swing easing method starts off slowly before gaining speed and slows down again towards the end of the animation , which makes it look more natural compared to Linear easing

<input name="animate" type="button" value="Swing" id="swing">

<script type="text/javascript">
$('#anim').toggle(function() {
$('p').animate({'height':'+=150px'}, 2000, 'linear');
}, function() {
$('p').animate({'height':'-=150px'}, 2000, 'linear');

$('#swing').toggle(function() {
$('p').animate({'height':'-=150px'}, 2000, 'swing');
}, function() {
$('p').animate({'height':'+=150px'}, 2000, 'swing');




  1. I see your "brief description on linear and swing easing methods", but I don't see your tutorial. There is just your code, script and html, "Download Demo" link is dead as well.
    Is this a live work in progress?
    Is the tutorial still to come?

    1. Hey Unknown thanks for pointing out
      i have updated the download link for easing tutorial
