Answer 1

You need to use a single toggle event. You are setting the click event twice and that won't work.

Answer 2

Use toggle instead of show/hide and toggleClass instead of add/remove, and merge into a single click event. Something like this (untested and probably doesn't work):

$("#click").click(function() {
    $("#ccc").toggle().animate();
    $(this).toggleClass('bbb aaa');
});

$(this).toggleClass('bbb aaa'); would be even better. – Lasalle

Answer 3

You are looking for the toggle event, it appears.

$(document).ready(function () {
    $('div#click').toggle(
        function () {
            $('div#ccc').slideDown('fast').show();
            $('div#click').removeClass('bbb').addClass('aaa');
        },
        function () {
            $('div#ccc').slideDown('fast').hide();
            $('div#click').removeClass('aaa').addClass('bbb');
        });
    });
