Adding a box-shadow to a card-like element

Tell us what’s happening:
So I tried out the format which I will copy and paste to demonstrate.
I have two criterias I have to pass, and so far I only passed one. The one I am struggling with is " Your code should add a box-shadow property for the thumbnail id."
could someone provide me some insight on what I should be doing in addition to what I imputed into the database?

  **Your code so far**


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;
.cardContent {
  padding: 10px;
.cardText {
  margin-bottom: 30px;
<div class="fullCard" id="thumbnail" 
box-shadow:0 10px 20px rgba(0,0,0,0.19), 0 6px 6px rgba(0,0,0,0.23);>
<div class="cardContent">
  <div class="cardText">
    <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 class="cardLinks">
    <a href="" target="_blank" class="links">Larry Page</a><br><br>
    <a href="" target="_blank" class="links">Sergey Brin</a>

Challenge: Add a box-shadow to a Card-like Element

Hi @Sherif123 !

You put it in the wrong spot.

You are not supposed to put the actual styles in this div. Just the id name.

The styles need to be in the style section.

styles go here

make sense?

It worked!! thanks so much! I’m not sure why the instructions weren’t that specific. But nonetheless, I really appreciate your time and help thank you!
