Silver Background Not Working

Tell us what’s happening:

After typing in the necessary code to turn my div section’s background silver, the challenge says I did everything correctly, except it says that the background isn’t silver. The preview even shows a silver background, despite it saying that it isn’t silver. This is very frustrating and I can’t figure out any reason why this should be failing.

Your code so far

<link href="" rel="stylesheet" type="text/css">
.red-text {
  color: red;

h2 {
  font-family: Lobster, monospace;

p {
  font-size: 16px;
  font-family: monospace;

.thick-green-border {
  border-color: green;
  border-width: 10px;
  border-style: solid;
  border-radius: 50%;

.smaller-image {
  width: 100px;

.silver-background {
  background-color: silver;

<h2 class="red-text">CatPhotoApp</h2>
<p class="red-text">Click here to view more <a href="#">cat photos</a>.</p>

<a href="#"><img class="smaller-image thick-green-border" src="" alt="A cute orange cat lying on its back."></a>

<div class="silver-background">
  <p>Things cats love:</p>
    <li>cat nip</li>
    <li>laser pointers</li>
  <p>Top 3 things cats hate:</p>
    <li>flea treatment</li>
    <li>other cats</li>

<form action="/submit-cat-photo">
  <label><input type="radio" name="indoor-outdoor" checked> Indoor</label>
  <label><input type="radio" name="indoor-outdoor"> Outdoor</label><br>
  <label><input type="checkbox" name="personality" checked> Loving</label>
  <label><input type="checkbox" name="personality"> Lazy</label>
  <label><input type="checkbox" name="personality"> Energetic</label><br>
  <input type="text" placeholder="cat photo URL" required>
  <button type="submit">Submit</button>

Challenge: Give a Background Color to a div Element

Link to the challenge:

Hello. It does work.

It gives me check marks for everything except “Your div element should have a silver background”

I literally copypasted your code and it passed the test (also i can’t spot anything wrong). Did you change anything from it after posting? Or try refreshing the browser tab where the challenge is and running the tests again, maybe it broke somehow.

A friend of mine tested the code as well and it worked. I tried refreshing and it didn’t do anything to fix it, so I’m not sure what’s going on.

I’m thinking it may be my browser. I tried it on Edge and it worked.
