jQuery CSS3 Animation Queue

jQuery CSS3 animation queue is a plugin to chain CSS3 animations one at a time, as well as delay the animation until the element is in the browser viewport.


To install via npm:

$ npm install jquery-css3-animation-queue --save

Basic Usage

  1. Include jQuery and jquery-css3-animation-queue.js in your document
<script type="text/javascript" src="./jQuery.js"></script>
<script type="text/javascript" src="./jquery-css3-animation-queue.js"></script>
  1. Add the rule to delay the animations to your CSS.
/* Required rule. Add to your CSS file */
.animated.standby {
  -webkit-animation: none !important;
  -o-animation: none !important;
  animation: none !important;
  visibility: hidden;
  1. Create CSS3 animation rules. Recommendation: use animate.css for a large list of ready animations.
  1. Add the classes animated and standby to the element you want to animate. Also remember to add whichever classes you need for your animation rules.

Full example:

<h1 class="animated standby fadeIn">Example</h1>


The plugin reads the data properties delay and offset on each element.


Default value: 300

The delay property determines how much time to wait, in milliseconds, before animating the next element in the queue. This is separate to the actual CSS animation duration and may contain a different value.

To override the default value, you can set your own value to the global window variable in your JavaScript.

window.jqueryCss3AnimationQueue.settings.delay = 5000;

Each animated element can also have a data-delay attribute which will override the default.

<div class="animated standby fadeIn" data-delay="2000">
  The next element in queue will animate in two seconds.


Default value: 150

The offset property determines how much space, in pixels, between the bottom of the browser and the top of the element before the element is added to the active queue. Higher numbers mean the user will have to scroll down more before animation starts.

To override the default value, you can set your own value to the global window variable in your JavaScript.

window.jqueryCss3AnimationQueue.settings.offset = 500;

Each animated element can also have a data-offset attribute which will override the default.

<div class="animated standby fadeIn" data-offset="200">
  This element will be added to the animation queue when the space between the
  bottom of the browser and the top of the element is more than 200 pixels.

Sort By Offset Top

Default value: true

The plugin will also attempt to sort the queue by the top position of each element. Elements lower in the DOM but higher in position due to negative margins or absolute / fixed positions would be in front of the queue. A side effect is that multiple elements on the same line may animate out of order, due to having the same top position.

You can disable the sort function in your JavaScript. Due to this setting affecting multiple elements, there is no per-element override. However, this setting can be toggled on and off as needed without breaking the plugin.

window.jqueryCss3AnimationQueue.settings.applySort = false;

Immediate Animation on elements above fold

Default value: true

If the user starts in the middle of a page or scrolls quickly to the bottom, the plugin might take a long time to reach elements in their viewport.

By default, when the page loads and when the user scrolls, the plugin will immediately trigger the elements above the fold. This feature can be disabled if you decide that the plugin is triggering elements too quickly.

window.jqueryCss3AnimationQueue.settings.triggerViewport = false;

You can also manually trigger the all elements above a certain point on the page.

// Immediately trigger items above fold
var scrollTop = $(window).scrollTop();
$.fn.jqueryCss3AnimationQueue('immediateAnimation', scrollTop);


Load New Elements

The plugin comes with several methods that you can call manually from outside the plugin. The most common one is update.

The plugin caches all animated elements on document ready in order to improve performance. The update method will clear the animation queue and reacquire elements with the classes animated and standby.

$('.newly_added_div').addClass('animated standby fadeIn');

Event Listener

When the animation is activated, a event listener called animationQueue is triggered.

$('.double_animation.animated.fadeIn').on('animationQueue', function() {
