Learn CSS Variables by Building a City Skyline - Step 41

Tell us what’s happening:

You want to add the same gradient to the next two sections. Instead of doing that, create a new class selector called bb1-window, and move the height and background properties and values from .bb1a to the new class selector.

Please Tell us what’s happening in your own words.

Learning to describe problems is hard, but it is an important part of learning how to code.

Also, the more you say, the more we can help!

Hello @TeeWhye ! Nice to see you back in the forum community.

It is important to let the community know in your own words the problem and error message received to assure focused and accurate responses to your questions. If you find it difficult, just think of what you are saying to yourself about the error message as you read it.

Example:  "Why is it saying it does not pass, when I believe I did as the instructions asked me to do?"  The error states "Almost there but not correct."

These are my words as an example. 
But, we would appreciate you telling us in your words which can help
 us understand a bit better.

This step asks us to move the background and height from the bb1a to the bb1-window selector.

You made a good attempt.

It appears you have copied and pasted them, instead of removing them completely from the bb1a, and adding them to the bb1-window.
Try removing them from the bb1a and see if the code will pass for you.

Wishing you good progress on your coding journey! :slightly_smiling_face:
