Stuck with css exercise

Hi,

In the exercise t the end of the css basics, there is a module called:

Attach a Fallback value to a CSS Variable. I have done the fallback to black to the background property of .penguin-top and .penguin-botton exactly as suggested in the exercise and the video (as is it shown below). But i does not seem to work, so I can´ t finnish the css module.

Does anyone know if there is a bug or something?

Thanks in advance.

<style>
  .penguin {
    --penguin-skin: black;
</style>

.penguin-top {
    top: 10%;
    left: 25%;


    /* Change code below this line */
    background: var(--penguin-skin, black);
    /* Change code above this line */

.penguin-bottom {
    top: 40%;
    left: 23.5%;

 /* Change code below this line */
    background: var(--penguin-skin, black);
    /* Change code above this line */

It was this url, but I found the answer:

I had fixed the typo when I was asked not to do it (in order to test the fallback).

Thanks a lot for your advise: I will place the 3 backsticks and use the Ask for Help button in the future.

Greetings,
