Learn CSS Variables by Building a City Skyline - Step 18

Tell us what’s happening:
The challenge is asking me to " Nest three new div elements in the .background-buildings container and give them the classes of bb2 , bb3 , and bb4 in that order. These will be three more buildings for the background"

I tried to do so but it isnt coming out right. The hint keeps saying i should create 3 new divs which i did.

Could someone help me find where I am going wrong?

Your code so far

Link to the challenge:

Instructions don’t tell you to add a class of “background-buildings” to a new ‘div’ element.

Yes, I took it out. I solved it.
