Challenge: Use CSS Selectors to Style Elements

Link to the challenge:

I tested your code and it works for me.
Try to clear out your catch and refresh the webpage.
Also if you are using dark mode try turning it off their is some know issue with it
If that doesn’t work try another browser

do you have maybe a dark mode extension that changes color of the page?
