  p {

    font-family: Monospace;

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

  .smaller-image {
    width: 100px;
   div { 
     background-color: silver;}

<h2 class="red-text">CatPhotoApp</h2>

<p>Click here for <a href="#">cat photos</a>.</p>

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

Link to the challenge:

If you want to add an inline style on a div. Your code should be like

<div style="background-color: silver;"></div>

or If you want to add a class with the ff style

.silver-bg {
background-color: silver;

<div class="silver-bg"></div>

But what i have is showing as correct but it wont allow me to continue, why does that do that?
What it says to do doesn’t work

My class is the same as yours except I didnt close it.
But tried that and it will allow me to go on but doesn’t show the silver bg
I am almost sure it should show a silver bg,This is crazy

I think it renders the right color because of this line in your code.

div { 
     background-color: silver;

but this line has incorrect syntax

<div class="silver:background;">

You should put here the name of the class not the style.

The goal of the lesson is to create a class called silver-background with the background-color of silver and assign this class to your div element.

You may have been seeing the same result, but it is incorrect because it says you need to create a class that will give a silver background, not explicitly style a div with a silver background.
