Hi ,I'm stuck on step 44 of skyline :(

Hey, so I’m currently working on the city skyline project step 40. For this challenge you must add a background property to class bb1a and apply linear gradient. I just don’t know what I’m doing wrong and wanted to ask if any of you have a clue on what im doing wrong.
This is what I’ve got until now →

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

Your CSS passes for me. Would you happen to have any browser extensions installed that change the color on the page, such as dark mode extensions? If so, you’ll probabaly have to disable those in order to pass any tests based on color.

Thank you for the answer. Tbh I don’t think so, when I click to look if my result is correct I get ‘You should apply a background to .bb1a .’ as a hint. :frowning:
