Challenge: Learn CSS Variables by Building a City Skyline - Step 112

Link to the challenge:

.sky {

}

This is an empty ruleset, so it doesn’t do anything and doesn’t have any effect on your page. You’ll need to put some property/values inside of it, specifically the ones the instructions are asking you to add.

Also, it looks like you may have deleted the closing curly brace on the .window-wrap ruleset above.

Hey! If you look closely here, the problem isn’t with the class itself. but it looks like you forgot to close the previous ruleset which is causing the .sky ruleset to not be recognised.

ongod, i love you!!!

It is great that you solved the challenge, but instead of posting your full working solution, it is best to stay focused on answering the original poster’s question(s) and help guide them with hints and suggestions to solve their own issues with the challenge.

We are trying to cut back on the number of spoiler solutions found on the forum and instead focus on helping other campers with their questions and definitely not posting full working solutions.
