jQuery.Keyframes generates and plays CSS3 keyframes quickly and easily allowing you to concentrate on the content of your project whilst cutting down code.
With the rise of CSS3 and HTML5, we see more and more usage of fancy features like transformations, translations, rotations and scaling. jQuery has a very nice built in $(selector).animate() function which allows for easy setup of these animations. However, jQuery's animate() does not support multiple keyframes. jQuery.Keyframes helps you accomplish just that.
In order for jQuery.Keyframes to work the jQuery library needs to be linked either through CDN:
<script src='http://code.jquery.com/jquery-<version>[.min].js'></script>or local copy:
<script src='/path/to/jquery-<version>[.min].js'></script>Include script in the head of your document using the following line:
<script src='/path/to/jquery.keyframes[.min].js'></script>Get browser style prefix
//Note support for adding prefixes for you is in progress
var vendorPrefix = $.keyframe.getVendorPrefix();Detecting CSS animation support
var supportedFlag = $.keyframe.isSupported();Adding a new animation sequence (keyframe)
$.keyframe.define([{
name: 'trapdoor-sequence',
'0%': {'height': '70px'},
'30%': {'height': '10px'},
'60%': {'height': '30px'},
'100%': {'height': '10px'}
}]);Adding a single frame style
$.keyframe.define({
name: 'ball-roll',
from: {
'transform': 'rotate(0deg)' //Note that 'transform' will be autoprefixed for you
},
to: {
'transform': 'rotate(360deg)' //Note that 'transform' will be autoprefixed for you
}
});Adding multiple frame styles
$.keyframe.define([{
name: 'roll-clockwise',
'0%': {
'margin-left' : '0px',
'background-color' : 'red',
'transform' : 'rotate(0deg)'
},
'100%': {
'margin-left' : '600px',
'transform' : 'rotate(360deg)'
}
},{
name: 'roll-anti-clockwise',
'0%': {
'margin-left' : '0px',
'background-color' : 'red',
'transform' : 'rotate(0deg)'
},
'100%': {
'margin-left' : '600px',
'transform' : 'rotate(-360deg)'
}
}
]);Adding styles and properties in array fashion
Gives resemblance to CSS styling definitions
var shake_start = {'transform': 'translate(0px)'};
var shake_odd1 = {'transform': 'translate(-10px, -10px)'};
var shake_even1 = {'transform': 'translate(10px, 10px)'};
var shake_odd2 = {'transform': 'translate(10px, -10px)'};
var shake_even2 = {'transform': 'translate(-10px, 10px)'};
$.keyframe.define([{
name: 'crazy',
'0%': shake_start,
'10%': shake_odd2,
'20%': shake_even1,
'30%': shake_odd2,
'40%': shake_even2,
'50%': shake_odd2,
'60%': shake_even1,
'70%': shake_odd1,
'80%': shake_even2,
'90%': shake_odd1
}

Playing an animation
$(selector).playKeyframe({
name: 'trapdoor-sequence', // name of the keyframe you want to bind to the selected element
duration: 1000, // [optional, default: 0, in ms] how long you want it to last in milliseconds
timingFunction: 'linear', // [optional, default: ease] specifies the speed curve of the animation
delay: 0, //[optional, default: 0, in ms] how long you want to wait before the animation starts in milliseconds, default value is 0
repeat: 'infinite', //[optional, default:1] how many times you want the animation to repeat, default value is 1
direction: 'normal', //[optional, default: 'normal'] which direction you want the frames to flow, default value is normal
fillMode: 'forwards', //[optional, default: 'forward'] how to apply the styles outside the animation time, default value is forwards
complete: function(){} //[optional] Function fired after the animation is complete. If repeat is infinite, the function will be fired every time the animation is restarted.
});Playing an animation (shorthand)
$(selector).playKeyframe(
'trapdoor-sequence 1000 linear 0 infinite normal forwards',
complete
);Reset the animation
$(selector).resetKeyframe(callback);Freeze keyframe animation and kill callbacks
$(selector).pauseKeyframe();Resume keyframe animation
$(selector).resumeKeyframe();
