You should create four new div elementshttps://www.freecodecamp.org/learn/full-stack-developer/workshop-city-skyline/step-8

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8" />
  <title>City Skyline</title>
  <link rel="stylesheet" href="styles.css" />
</head>
<body>
  <main id="main-doc">
    <section class="background-buildings">
      <div class="bb1"></div>
      <div class="bb2"></div>
      <div class="bb3"></div>
      <div class="bb4"></div>
    </section>
  </main>
</body>
</html>

* {
    border: 1px solid black;
    box-sizing: border-box;
}

body {
    height: 100vh;
    margin: 0;
    overflow: hidden;
}

.background-buildings {
    width: 100%;
    height: 100%;
}

.bb1 {

Hey Marvin! For Step 8, double-check your bb1 element. It should open and then contain four empty elements inside it, all before it closes.
Think of it like a box with four smaller boxes inside. That’s what “nesting” means.
You’re really close — once those are in place, the error should go away. Keep going!

why did you add the .bb2, .bb3 and .bb4 elements? those will come in a future step

creating elements before the instructions ask you to create them can cause tests to fail
