Tell us what’s happening:

I try to post my answer, it writes “running test” but nothing happens. What’s the problem?

Your code so far


<style>
  h4 {
    text-align: center;
  }
  p {
    text-align: justify;
  }
  .links {
    margin-right: 20px;
    
  }
  .fullCard {
    border: 1px solid #ccc;
    border-radius: 5px;
    margin: 10px 5px;
    padding: 4px;
  }
  .cardContent {
    padding: 10px;
  }
</style>
<div class="fullCard">
  <div class="cardContent">
    <div class="cardText">
      <h4>Google</h4>
