You should be able to use CSS (http://docs.jquery.com/CSS/css#name). You may have to be more specific such as “padding-left” or “margin-top”.
Example:
CSS
a, a:link, a:hover, a:visited, a:active {color:black;margin-top:10px;text-decoration: none;}
JS
$("a").css("margin-top");
The result is 10px.
If you want to get the integer value, you can do the following:
parseInt($("a").css("margin-top"))
