Challenge: Learn CSS Variables by Building a City Skyline - Step 23

Link to the challenge:

This is what you have at the start of this step:

background-color: var(--building-color2);

Because you don’t “have” this color yet, it doesn’t work. We now learn that we need a fallback color, the color that will be used when/if the first color fails to load.

This is how you use it:

var(--variable-name, fallback-value);

--variable-name is the first option, if it fails, it’s going to load fallback-value.

You already have the main color set up, you only need to add the fallback color, green.
