You have the closing paren in the wrong spot. The fallback color is part of the var.

ah thank you. i updated it to this but it’s still not working?

.bb2 {
width: 10%;
height: 50%;
background-color: var(-–building-color2, green)
}

You need to paste your code in here properly so we can see it.

To display your code in here you need to wrap it in triple back ticks. On a line by itself type three back ticks. Then on the first line below the three back ticks paste in your code. Then below your code on a new line type three more back ticks. The back tick on my keyboard is in the upper left just above the Tab key and below the Esc key. You may also be able to use Ctrl+e to automatically give you the triple back ticks while you are typing in the this editor and the cursor is on a line by itself. Alternatively, with the cursor on a line by itself, you can use the </> button above the editor to add the triple back ticks.

Those double dashes before building-color2 don’t look right. I would delete them and then add them again.

You used backslashes instead of back ticks. If you can’t find the back tick on your keyboard then use the </> in the editor menu bar (just make sure that the cursor is on a line by itself when you do).

sorry, here is the code:

.bb2 {
  width: 10%;
  height: 50%;
  background-color: var(--building-color2 green);
}

It worked. i was missing the comma. thank you!!
