Describe your issue in detail here.
so I need to change background-color to background on .red, when I do so the site say that it’s wrong, maybe it’s bug or I don’t understand something ?

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

.container {
background-color: rgb(255, 255, 255);
padding: 10px 0;

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

.red {
background: rgb(255, 0, 0);

.green {
background-color: #007F00;

.blue {
background-color: hsl(240, 100%, 50%);
