Create elegant HTML5 animations in responsive design easily and quickly, with only one line of javascript code!

You describe the DOM objects that you want to animate, attached them to the animation machine, and let's animate!

To use it, have a look on the examples provided...

What is iFSMAnimation ?

iFSMAnimation is javascript library that allows to create animations from an html description.


Getting started

Mainly, you need to create:

  • a HTML 'section' (or whatever) that will define where is defined the animation and HTML 'articles' to define the different objects that must be animated.
  • at the end, add a little script to start the animation...
  • that's it! You've got an animation that is RESPONSIVE ! Without having to know how to write javascript code lines...

First Example

The following example is a full animation that displays four pictures where different animations are applied. You could use this example as a starter template...

<!DOCTYPE html>
                <script src="../extlib/jquery-3.2.0.min.js"></script>
                <script src="../extlib/iFSM/iFSM.compressed.js"></script>
                <script src="../iFSMAnimation.js"></script>
                        article {opacity:0;}
                <div id="animation">

                <section id="animation-objects"
                        <article id="HappyNewYear_B"
                                data-enter-animation="display, 1000, 90, 104, 90, 104"
                                <img src="images/B.png">
                        <article id="HappyNewYear_O"
                                <img src="images/O.png">
                        <article id="HappyNewYear_N3"
                                <img src="images/N.png">
                        <article id="HappyNewYear_star"
                                <img src="images/etoile.png">
                        $(document).ready(function() {
                                //initialize and start the general animation

General process

An animation is defined by a main animation object attached to a container such a 'section'.

Within the container, you define the different animated objects attached/described by a subcontainer that is by default an 'article'.

Take care to give an id to each object you will animate.

The animation starts by calling each animated objects using the 'data-enter-animation' and just after 'data-animation' attributes to animate them.

When all objects were animated, the animation applies the 'data-exit-animation' definition of every animated objects to ending their animations, and then loops back.

Attributes on the main container


The 'data-delay-before-restart' attribute allows to define the delay before the animation restarts.


<section id="animation-objects" data-delay-before-restart="10000">


Boolean, if 'true', the animation will be 'responsive'. Limitations known with using 'specialAnimate'.


<section id="animation-objects" data-box-responsive="true">


"BoxWidth,BoxHeight" give the used dimensions as reference for the position of the animated objects. Useful in Responsive mode.


<section id="animation-objects" data-box-size-reference="551,551" >


Boolean, if 'true', the width and height will be fixed in order that the animation is fully shown on the window display. Example:

<section id="animation-objects" data-keep-height-visible="true">


Actually, a 'div' embeds the animation. It is possible to define the class that should be used on this div.


<section id="animation-objects" data-div-class="animation">


A loader may be set during initialization.

To display a loader, just indicate the class to use with the data-loader-class attribute.


<section id="animation-objects" data-loader-class="myLoaderClass">

Attributes on a sub container

data-enter-animation / data-animation / data-exit-animation

These attributes define the animation of the object.

The available animation are:

  • dummy - non animation
  • animate - animate article from current position or startposition to destination
    • duration
    • destination-left
    • destination-top
    • startposition-left - optional
    • startposition-top - optional
    • easing function - see - optional
  • display - display article (opacity set to 1) with animation from current position or startposition to destination
    • duration
    • destination-left
    • destination-top
    • startposition-left - optional
    • startposition-top - optional
    • easing function - see - optional
  • smoothHide - display article (opacity set to 0) with animation from current position or startposition to destination
    • duration
    • destination-left
    • destination-top
    • startposition-left - optional
    • startposition-top - optional
    • easing function - see - optional
  • rotate - rotate article
    • duration
    • angle
  • loop - loop animation
    • duration
    • destination-left
    • destination-top
    • startposition-left - optional
    • startposition-top - optional
    • loops number - optional default:infinite - give the number of loops
    • loop back delay - optional default: duration - give the delay to go to the initial position
  • specialAnimate, specialAnimateNoWait
    • duration
    • animation description object as in jQuery. ex: {left: 20;top:100;width:300}
    • void
    • void
    • void
    • easing function - see - optional
  • animateNoWait - same as animate but does not wait the end of animation to start the next animation
  • displayNoWait - same as display but does not wait the end of animation to start the next animation
  • smoothHideNoWait - same as smoothHide but does not wait the end of animation to start the next animation
  • rotateNoWait - same as rotate but does not wait the end of animation to start the next animation

Start the animation with javascript

To start the animation, you will need to add this script:

$(document).ready(function() {
	//initialize and start the general animation

You can define some options: animationSequence

array, defines the order of animation of the objects. By default, the order is the one found in the DOM.


string, gives the HTML tag to find the animated objects (in css/jquery format).


var myAnimationSequence=['#myAnimObj2','#myAnimObj1'];


In order to have the animation playing correctly, you can use the following css as a start:

body {
	margin		: 0px;
	padding		: 0px;
	text-align	: center;
/*for the div that embeds your animation section, will center it*/
#animation, .animation {
	margin : 0 20% 30px 20%;
/*for the main animation section container, let's have a background*/
#animation-objects,.animated_section {
	background-color:	#1c3970;
/*for the animated objects (here, all objects will start as hidden at beginning - opacity=0)*/
section#animation-objects article {
	opacity		: 0;


The 'examples' folder gives you some examples on how to animate your DOM objects with iFSMAnimation...


To work properly, you need to include the following javascript library:

  • jQuery (>= 3.2) <script type="text/javascript" src="extlib/jquery-1.10.2.min.js"></script>
  • iFSM by intersel
    • this library manages finite state machines and needs these libraries:
      • doTimeout by "Cowboy" Ben Alman
        • this library brings some very usefull feature on the usual javascript setTimeout function like Debouncing, Delays & Polling Loops, Hover Intent...
        • <script type="text/javascript" src="extlib/jquery.dotimeout.js"></script>
      • attrchange by Selvakumar Arumugam](
        • a simple jQuery function to bind a listener function to any HTML element on attribute change
        • <script type="text/javascript" src="extlib/jquery.attrchange.js"></script>
  • waitForImages by Alexander Dickson, in order to garantee that all images of the animation are downloaded and ready. This library is automatically loaded by iFSMAnimation.
  • jQuery UI may be used to apply some effect on the animated objects as swing, easing, ...
  • jquery.path may be used to defined arc and bezier for the path of animated objects.
  • FitText.js may be used to have 'responsive' texts

If you need to do some specific animations, these libraries may be useful:

  • jquery.path - allows to animate objects following a path as an arc or a curve


  • my objects don't seem to be correctly positionned on the Y axe.
    • Did you correctly set the "<!DOCTYPE html>" at the beginning of your file? without it, strange behaviour occurs!
  • iFSMAnimation loads all its jquery libraries... but they are still loaded...
    • you can empty the list of the libraries to load using the option 'ANIMATION_NEEDED_SCRIPTS':

Still some questions?

If you have questions or unsolved problems, you can have a look on the our FAQs or leave a message on the Issue board.
