Tell us what’s happening:

I really don’t know whay is wrong, I can’t get it,
background: linear-gradient var(–building-color1, --window-color1)

You should give the background a linear-gradient starting from var(--building-color1) .

Hi, can you please paste the instruction here so hopefully I can help you out!!

Gradients in CSS are a way to transition between colors across the distance of an element. They are applied to the background property and the syntax looks like this:

gradient-type(
  color1,
  color2
);

In the example, color1 is solid at the top, color2 is solid at the bottom, and in between it transitions evenly from one to the next. In .bb1a, add a background property below the background-color property. Set it as a gradient of type linear-gradient that uses --building-color1 as the first color and --window-color1 as the second.
THANKSSS

Your second color is missing the var word if its a variable then it needs to have var at the beginning, and your linear-gradient is not correct there should be a pair of()

linear-gradient(colors here)

Each variable should also have its own pair of ()

6

I did it this way
background: linear-gradient var(–building-color1), var(–window-color1);
And is still wrong

7

You wrote
linear-gradient var(–building-color1, --window-color1);
and the example says
gradient-type(
color1,
color2
);
I don’t think that the var is part of the syntax, could you change it so it follows the example syntax exactly?

Because you still dont have the () for your linear gradient

Here is an article with some examples

The () needs to be right after linear gradient, like this:

for e.g.
gradient-type()
