Animate opacity doesn't work properly on IE

Question

I\'m trying to use animate() to change the height and opacity of a div. The div has an image background in CSS. It works fine on Firefox and Safari

Answer 1

I was under the impression that jQuery did the whole opacity support thing for you. Does this work for all browsers?

$('#list_box').animate({opacity: '1',height: '300px',top: newTop},{duration: 300});
