Why do you wrote rgba() color?

3 
.bb2 {
  width: 10%;
  height: 50%;
  background-color: var(--building-color2);
}

This is the original code.

Add a fallback value of green to the background-color of .bb2

And this is the instruction.

All you needed to do in this step is add the fallback value. But you changed the var() color. There is no variable --background-color. background-color is a property.

`you need to add the colour to the background color with a comma to seperate the colours as your fall back value just read the instruction exactly and you can’t go wrong, if not then i will see if i can help thanks. Ian
