The background is set, but you need to correctly apply the “linear-gradient” as its color.
something like:

something {
  background: linear-gradient( color1, color2, color3, etc );
}

Now just do that as it asks you:
Add a linear-gradient to .bb1d with orange as the first color, --building-color1 as the second, and --window-color1 as the third. Remember to use the gradient on the background property.

Here’s the .bb1d source part:

.bb1d {
    width: 100%;
    height: 70%;
    background-color: var(--building-color1);
    background: linear-gradient(
        orange,
        var(--building-color1),
        var(--window-color1)
    );
}

And I still get an error/hint when I test the code.
This hint also comes for all parts of the “Learn CSS Variables” challenge where I have to use linear-gradient in the background.
The usage of linear-gradient looks fine to me.
What am I missing?
Does anyone have a solution for how to pass the test?

remove the background-color

Your code is correct, remove the extra background-color you typed just like @gladlo said.

6

Even after removing the background-color and checking the code,
I still get the message:

“You should use the background on .bb1d .”

This is the code I checked:

.bb1d {
    width: 100%;
    height: 70%;
    background: linear-gradient(
        orange,
        var(--building-color1),
        var(--window-color1)
    );
}

Did you try restarting step and typing it again? If you’re using Safari browser try chrome please.
