Please describe how to reproduce this issue, and include links to screenshots if possible.
In the descriptionof the challenge, it uses <i> to replace the italicized text with jquery instead of the <em> tag. In a previous challenge it mentions how <i>is outdated and usually used for icons in bootstrap now

ie.
$("h3").html("<i>jQuery Playground</i>");
should be:
$("h3").html("<em>jQuery Playground</em>");

My code:

<script>
  $(document).ready(function() {
    $("#target1").css("color", "red");

  });
</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>
