jQuery: if my css visibility:hidden, how can i appear my elements?

in my css i've set some elements visibiliy:hidden, how can I show them? I've done it before with opacity, but i've some bug in IE: ``` var i = 0; $mySelection.each(function(i) { $(this).delay((i * 100) + ($mySelection.length)).animate( { opacity: "1"}, {queue:true, duration:1000, easing:"quartEaseIn"} ); }) ``` How can i do if I want controll visibility with jQuery instead of opacity? thank you
