Do not alter any other text

Tell us what’s happening:
For some reason I get all the checkmarks except for “do not alter any other text”
I can’t figure out what is happening.

Your code so far

<script>
  $(document).ready(function() {
    $("#target1").css("color", "red");
    $("h3").html("<em>jQuery Playground</em>");
    $("#target4").html("<em>#target4</em>");

  });
</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>

You don’t need to do anything with the <h3> element.

Thanks. I didn’t change any code from when the page loaded except the $(#target4). The instructions were kind of ambiguous there.
