jQuery Animation - Smooth Size Transition

Question

So this might be really simple, but I haven\'t been able to find any examples to learn off of yet, so please bear with me. ;)

Here\'s basically what I want to do:

Answer 1

maybe something like this?

$(".testLink").click(function(event) {
    event.preventDefault();
    $(".testDiv").hide(400,function(event) {
        $(this).html("Itsy-bitsy bit of content!").show(400);
    });
});

Close to what I think you wanted, also try slideIn/slideOut or look at the UI/Effects plugin.
