Hi there,

You can look at the example code in the instruction:

gradient-type(
  color1,
  color2
);

There are no var before gradient-type.

And the variable name should be put inside var(), like the one on the line right above:

Okay, so I was actually stuck on this for a couple minutes but the answer was quite simple. It seems you have added var right before the linear-gradient. The var function is used to insert the value of a variable, so make sure you insert the value of the variable twice because you are blending two variables together.

.bb1a {
  width: 70%;
  height: 10%;
  background-color: var(--building-color1);
  background: var linear-gradient(
    --building-color1,
    --window-color1
    );
}

*If your still stuck may hint would be: place your var's inside the linear-gradient's brackets.

Hi there,
So after carefully studying step 40, I found the solution

It is great that you solved the challenge, but instead of posting your full working solution, it is best to stay focused on answering the original poster’s question(s) and help guide them with hints and suggestions to solve their own issues with the challenge.

We are trying to cut back on the number of spoiler solutions found on the forum and instead focus on helping other campers with their questions and definitely not posting full working solutions.
