Add a box-shadow to a Card-like Element - HELP

Hi guys,
I have done this so far - but cant understand what I am doing wrong - " Your code should add
box-shadow property for the thumbnail id."

<style>
  h4 {
    text-align: center;
    background-color: rgba(45, 45, 45, 0.1);
    padding: 10px;
    font-size: 27px;
  }
  p {
    text-align: justify;
  }
  .links {
    text-align: left;
    color: black;
  }


  .fullCard {
    width: 245px;
    border: 1px solid #ccc;
    border-radius: 5px;
    margin: 10px 5px;
    padding: 4px;
    box-shadow: 0 10px 20px rgba(0,0,0,0.19), 0 6px 6px rgba(0,0,0,0.23);
    
  }
  .cardContent {
    padding: 10px;
  }
  .cardText {
    margin-bottom: 30px;
  }
</style>
<div class="fullCard" id="thumbnail">
  <div class="cardContent">
    <div class="cardText">
      <h4>Alphabet</h4>
      <hr>
      <p><em>Google was founded by Larry Page and Sergey Brin while they were <u>Ph.D. students</u> at <strong>Stanford University</strong>.</em></p>
    </div>
    <div class="cardLinks">
      <a href="https://en.wikipedia.org/wiki/Larry_Page" target="_blank" class="links">Larry Page</a><br><br>
      <a href="https://en.wikipedia.org/wiki/Sergey_Brin" target="_blank" class="links">Sergey Brin</a>
    </div>

I’ve edited your post for readability. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.

See this post to find the backtick on your keyboard. The “preformatted text” tool in the editor (</>) will also add backticks around text.

Note: Backticks are not single quotes.

you need to use the selector they ask you to use, which is the thumbnail id, you are using the fullCard class as selector instead
