Learn CSS Variables by Building a City Skyline Step 44

Hey there! I was trying back and forth with this but it wont work.
This is my code:
.bb1d {
width: 100%;
height: 70%;
background-color: var(–building-color1);
background: linear-gradient (
orange, var(–building-color1), var(–window-color1)
);
}

I declared the variables in :root and this worked. I get this error message whatever I do:
You should use the background on .bb1d .
Please help me! Kind regards, Carolin

I don’t know why but the double – in :root are gone while copy & paste here. But they are there

I’ve edited your code for readability. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.

You can also use the “preformatted text” tool in the editor (</>) to add backticks around text.

See this post to find the backtick on your keyboard.
Note: Backticks (`) are not single quotes (').

Your code should be in formatted.
example;

h1{
  background: linear-gradient (
      green,
      var(--building-color2),
      var(--window-color50)
   );
}

}

When I copy and paste this code the challenge passes for me

  1. You can try forcing a refresh (ctrl+ f5)
  2. Make sure you dont have any browser extensions enabled when you submit the challenge
  3. submit the challenge in a different browser

I have no clue why but I copied my code snippet from above in again (same browser) and put a , in (after --window-color1))and then clicked ‘submit’ → it doesn’t work BUT when I removed it and clicked ‘submit’ again IT WORKED. I have no clue why but it’s done. Thank you all!
