ok thanks, I have added <span></span> inside the <li> and targeted that but it's not working?!
Code:
jQuery('ul#sections li#who a span').hover(function() {
jQuery(this).stop().animate({
marginTop : '-182px'
}, {queue:false,duration:600,easing:'easeInOutQuint'});
}, function(){
jQuery(this).stop().animate({
marginTop : '0px'
}, {queue:false,duration:850});
});
