Why it is not running

JavaScript

where the problem is coming my task is… Use the jQuery addClass() function to give the classes animated and shake to all your elements with the class well.

<script>
  $(document).ready(function() {
    $("button").addClass("animated bounce");
    $("well").addclass("animated shake");
   
  });
</script>

<!-- Only change code above this line. -->

<div class="container-fluid">
  <h3 class="text-primary text-center">jQuery Playground</h3>
  <div class="row">
    <div class="col-xs-6">
      <h4>#left-well</h4>
      <div class="well" id="left-well">
        <button class="btn btn-default target" id="target1">#target1</button>
        <button class="btn btn-default target" id="target2">#target2</button>
        <button class="btn btn-default target" id="target3">#target3</button>
      </div>
    </div>
    <div class="col-xs-6">
      <h4>#right-well</h4>
      <div class="well" id="right-well">
        <button class="btn btn-default target" id="target4">#target4</button>
        <button class="btn btn-default target" id="target5">#target5</button>
        <button class="btn btn-default target" id="target6">#target6</button>
      </div>
    </div>
  </div>
</div>

Still not running

 $("well").addClass("animated shake");

Note that, just like with CSS declarations, you type a . before the class’s name

I’d suggest you to reset your code before to retry :slight_smile:

Hope it helps,
