For some reason the code’s not running, is there a bug?

Your code so far


<style type='text/sass'>
  h3{
    text-align: center;
  }
  .info{
    width: 200px;
    border: 1px solid black;
    margin: 0 auto;
  }
  .info-important{
  @extend .info;
  background-color: magenta;
  
  
  
  
</style>
<h3>Posts</h3>
<div class="info-important">
  <p>This is an important post. It should extend the class ".info" and have its own CSS styles.</p>
</div>

<div class="info">
  <p>This is a simple post. It has basic styling and can be extended for other uses.</p>
</div>
