[SOLVED] Challenge 51 Learn CSS Variables - Seeking Help

Tell us what’s happening:
I’ve looked on the forum, and only found one post. It was solved but I’m struggling to see anything in common with the errors already pointed out there.

Usually, the hint isn’t particularly helpful either.

Hint: You should give .bb2b a background property.

Any help or direction anyone can provide, I would be immensely grateful.

Note: I have tried this with both Firefox (supported) and Safari (not so much).

Your code so far

.bb2b {
  width: 100%;
  height: 100%;
  background: linear-gradient(
    var(--building-color2 0%),
    var(--building-color2 6%),
    var(--window-color2 6%),
    var(--window-color2 9%)
