Learn CSS Variables by Building a City Skyline - Step 23

HTML-CSS

Tell us what’s happening:
I am not sure what I am missing. I have been searching the web and the forum for help/solution. Still my code does not pass.

I am stuck on step 23:

“You should add a fallback value of green to the background-color property.”

My attempts with no success are shown below.

  1. background-color: var(–background-color2, fallback-green);
    2)background-color: var(–background-color2, fallback: green);
    3)background-color: var(–background-color2, green);

Please help me figure out what I am missing.

  **Your code so far**
