Challenge: Learn CSS Variables by Building a City Skyline - Step 40

Link to the challenge:

You don’t want to create a new .bb1a selector for this. You want to add this to the existing .bb1a selector.

Also, do you remember the syntax you need to use to access custom CSS properties? Look at the existing background-color property on .bb1a for an example.
