No. The attribute may not be even mentioned in CSS, and your jQuery code maybe the first time the attribute is mentioned. It will still animate – from 0 to whatever value you indicate. \

Example:

<!DOCTYPE html PUBLIC “-//W3C//DTD XHTML 1.0 Strict//EN”
“http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd”>
<html>
<head>
<title>My Test Page</title>
<script type=”text/javascript” src=”js/jquery-1.5.2.min.js”></script>
<script type=”text/javascript”>
$(document).ready(function(){
$(‘:submit’).click(function(){
$(‘div’).animate({
padding:’50px’
});
});
});
</script>
</head>
<body>
<div style=”width:200px; height:200px;
background-color: gray; border:10px”>My div</div>
<br />
<input value=”Animate” type=”submit”></body>
</html>
