Learn CSS Colors by Building a Set of Colored Markers - Step 21

Hi, guys.
I don’t really know what the problem is…
When using one class selector,
{property: value;
I think I put the right one… please help me!
Your code so far

<!-- file: index.html -->
<!DOCTYPE html>
<html lang="en">
    <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">
    <h1>CSS Color Markers</h1>
    <div class="container">
      <div class="marker one">
      <div class="marker two">
      <div class="marker three">
/* file: styles.css */
h1 {
  text-align: center;

/* User Editable Region */

.contrainer {
background-color: rgb(0, 0, 0);

/* User Editable Region */

.marker {
  width: 200px;
  height: 25px;
  margin: 10px auto;

.one {
  background-color: red;
