问题
The JSTween library doesn't seem to perform a simple animation pulled from the library's tutorial. Using the following code, the alert box will show up after the allotted 1 second duration, but no animation will take place.
I must have set up the library wrong somehow, but I can't see the problem.
<html>
<head>
<style type="text/css">
#box
{
width: 16px;
height: 16px;
}
</style>
<script type="text/javascript" src="jquery-1.10.1.js"></script>
<script type="text/javascript" src="jstween-1.1.js" ></script>
<script type="text/javascript" src="jstween-1.1.min.js" ></script>
<script type="text/javascript">
function animate()
{
$('#box').tween({
width:{
start: 16,
stop: 200,
time: 0,
units: 'px',
duration: 1,
effect:'easeInOut',
onStop: function(){ alert( 'Done!' ); }
}
}).play();
}
</script>
</head>
<body>
<div id="box">
<img src="image.png" onClick="animate()" />
</div>
</body>
</html>
Additional info: using Safari on 10.7.5. Code does not work in Chrome or Firefox either.

For anyone who may read this in the future, I discovered the problem: the CSS element #box needs position: relative; as an attribute, otherwise the browser will hold the element in place by default.
