/* css */
@keyframes mymove {
    from {top:0px;}
    to {top:200px;}
}
==>
/* amo.js */
Amo.keyframes({
    top: '0px'
}, {
    top: '200px' 
});


/* css */
@keyframes mymove {
    0%   {top:0px;}
    50%  {top:100px;}
    100% {top:20px;}
}
==>
/* amo.js */
Amo.keyframes({
    0: {
        top: '0px' 
    },
    50: {
        top: '100px'
    },
    100: {
        top: '200px'
    }
});

keyframe.animate & animate.run

you can create animate depend on keyframe

/* css */
@keyframes mymove {
    0%   {top:0px;}
    50%  {top:100px;}
    100% {top:20px;}
}
#test {
    animation: mymove 5s linear 2s infinite alternate;
}
=>
/* amo.js */
var mymove = Amo.keyframes({
    0: {
        top: '0px' 
    },
    50: {
        top: '100px'
    },
    100: {
        top: '200px'
    }
});
var myAnim = mymove.animate({
    duration: 5000,
    easing: 'linear',
    delay: 2000,
    time: -1,
    direction: 'alternate'
});

//$('#test') => ok
//document.getElementById('test') => ok
myAnim.run($('#test'), function() {
    console.log('animation over'); 
});

animate instance

var myAnimIns = myAnim.run($('#test'), function() {
    console.log('animation over'); 
});

//you can stop the animation
myAnimIns.stop();

//you can start the animation too
myAnimIns.start();

//reset the animation
myAnimIns.reset();

You do not need care about the css animation's class and keyframes's style, focusing on animation is the only thing you need to do.
