To use a variable, put the variable name in parentheses with var in front of them like this: var(--variable-name). Whatever value you gave the variable will be applied to whatever property you use it on.

Add the variable --building-color1 you created in the previous step as the value of the background-color property of the .bb1a class.

.bb1a {
width: 70%;
height: 10%;
background-color: var(–building-color1#999);
}

What does this part here mean? It is a color?

How about this one? What is this one?

I have figure it out thanks bro or sis
