Challenge: Learn CSS Variables by Building a City Skyline - Step 25

Link to the challenge:

Hello!
The :root selector should be a new selector not added to any other existing selector.
I think you added it to another selector.
The variable( colors) need to be moved into the :root selector.
I hope this helps you.

Happy coding! :slight_smile:

still not working!! what to do i don’t know help!!

And… Can you show your code now?

Listen to @Gray.n.Grey : you need a new selector (:root) with all variables of the colors (they are in .bb1 selector. Remove from bb1 and add to :root)
