Learn CSS Variables by Building a City Skyline - Step 40

Tell us what’s happening:

Hi everyone, I have been facing a problem with my code. It looks good, but i still have this message about my code being wrong…

After creating the variable --window-color1 at the top of my css page, I applied a background property with the gradient-type. With the 2 colors between parentheses below the background-color property. Both colors are variables. The first --building-color1, and the second one --window-color1.

That’s what i try to apply to my .bb1a css rule but it won’t work… Do i need glasses??

Welcome to the forum @colabelrain

Just a few pieces of missing code:

  1. The two colours are missing the front part of the code which make them variables.
  2. Close the first colour.
  3. Close the linear-gradient.

Happy coding

After linear-gradient place a ( bracket and var and bracket () around building color variable.
