Step 49 Colored Markers (I'm confused)

The step seems pretty simple, but my code has not been accepted. Please help.

  **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%);

The code you have shared works on my end. Please ensure that you have disabled any extensions that interface with the freeCodeCamp website (such as Dark Mode and Ad Blocker), and set your browser zoom level to 100%. Both of these factors can cause tests to fail erroneously.

Or try another browser

I switched browsers and it worked. Thanks for the tip. I will try to remember to do this before coming to the forum for solutions from now on. Just in case.
