bad87fee1348bd9aecb08826	Use jQuery to Modify the Entire Page	link https://cdnjs.cloudflare.com/ajax/libs/animate.css/3.2.0/animate.css	6	18361

Description

We're done playing with our jQuery playground. Let's tear it down! jQuery can target the body element as well. Here's how we would make the entire body fade out: $("body").addClass("animated fadeOut"); But let's do something more dramatic. Add the classes animated and hinge to your body element.

Instructions

Tests

tests:
  - text: You should add the classes <code>animated</code> and <code>hinge</code> to your <code>body</code> element.
    testString: assert($('body').hasClass('animated') && $('body').hasClass('hinge'));

Challenge Seed

<script>
  $(document).ready(function() {
    $("#target1").css("color", "red");
    $("#target1").prop("disabled", true);
    $("#target4").remove();
    $("#target2").appendTo("#right-well");
    $("#target5").clone().appendTo("#left-well");
    $("#target1").parent().css("background-color", "red");
    $("#right-well").children().css("color", "orange");
    $("#left-well").children().css("color", "green");
    $(".target:nth-child(2)").addClass("animated bounce");
    $(".target:even").addClass("animated shake");

  });
