Learn CSS Colors by Building a Set of Colored Markers - Step 11

Tell us what’s happening:
I was asked to create a new CSS rule that targets the class marker, and set its background-color property to red. I did but its saying my code does not pass, and the hint says “You should create a class selector to target the marker class”. I’m confused, isn’t that what I did?

  **Your code so far**
/* file: index.html */
<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>Colored Markers</title>
  <link rel="stylesheet" href="styles.css">
</head>
<body>
  <h1>CSS Color Markers</h1>
  <div class="container">
    <div class="marker">
    </div>
  </div>
</body>
</html>
/* file: styles.css */
h1 {
text-align: center;
.marker {
background-color: red;
}
