Appearance -> Styles -> You Style -> Templates -> page_container_js_body
In the very beginning add the following code:
Code:
<script type="text/javascript">
$(document).ready(function(){
$("h3 a").hover(function(){
$(this).stop().animate({marginLeft:"10px"},300);}
,function(){
$(this).stop().animate({marginLeft:"0px"},300);
});
});
</script>
Thats it enjoy!
