I cant “see” the cat photo app I’m supposedly building in HTML/CSS
It says I’m supposed to be able to. I don’t get it
Your code so far

.injected-text {
  margin-bottom: -25px;
  text-align: center;

.box {
  border-style: solid;
  border-color: black;
  border-width: 5px;
  text-align: center;

.yellow-box {
  background-color: yellow;
  padding: 10px;

.red-box {
  background-color: crimson;
  color: #fff;
  padding: 20px;

.blue-box {
  background-color: blue;
  color: #fff;
  padding: 10px;
<h5 class="injected-text">margin</h5>

<div class="box yellow-box">
<h5 class="box red-box">padding</h5>
<h5 class="box blue-box">padding</h5>

Challenge: Adjust the Padding of an Element

Link to the challenge:

The challenge you linked doesn’t use the cat. The first line of the description says:

Now let’s put our Cat Photo App away for a little…

The failing test you have says:

Your blue-box class should give elements 20px of padding .

When I fix that, your code passes for me.

im not talking about my code. The UI of Freecodecamp wasn’t displaying the side panel on the right that shows you the cat app website or whatever it is youre making in the HTML. I just figured that out. But now I have to drag it open every single lesson. How do i get it pinned open?

Sorry, I can’t reproduce. For me, the panes reset every time I open a new challenge.

Could there be something with your browser? What browser are you using? What operating system? I don’t know if that setting is getting cached or something. That is, if I understand you.
