Learn CSS Transforms by Building a Penguin - Step 88

I get an error that my CSS file is not correct.

Hint

You should give .penguin-head a background of linear-gradient(45deg, var(--penguin-skin), rgb(239, 240, 228)).

Challenge: Learn CSS Transforms by Building a Penguin - Step 88

Link to the challenge:

your --penguin-skin is correct
and so is your .penguin-head background property.
Maybe you inadvertently changed something you shouldn’t that is causing this to fail?
can you reset and try it again?

In every place where you find :

background-color: gray;

you should change that “gray” value with the following:

var(--penguin-skin)

You have to do this at three places in your css code.

I did try resetting the code and copy and pasting the exact hint. No luck on it.

I also did that, no luck on it. Here is that update in case I am going crazy and missing something.

Now the code is correct. Try the following:
“Note: Some browser extensions, such as ad-blockers and dark mode extensions can interfere with the tests. If you face issues, we recommend disabling extensions that modify the content or layout of pages, while taking the course.”

No extensions on my browser. But am on Mac. Going to give it a shot on my windows computer when I am home from Holidays.
