Target with ID Selector

Bummer! Make sure you're using an ID selector that targets 'main-content'.

index.html
<!DOCTYPE html>
<html>
  <head>
    <title>Lake Tahoe</title>
    <link rel="stylesheet" href="page.css">
    <link rel="stylesheet" href="style.css">
  </head>
  <body> 
    <header class="main-header">
      <span>Journey through the Sierra Nevada Mountains</span>
      <h1 class="main-heading">Lake Tahoe, California</h1>
    </header>
    <p>
      Lake Tahoe is one of the most breathtaking attractions located in California. It's home to a number of ski resorts, summer outdoor recreation, and tourist attractions. Snow and skiing are a significant part of the area's reputation.
    </p>
    <a href="#">Find out more</a>
    <div id="main-content">
      <h2>Check out all the Wildlife</h2>
      <p>
        As spawning season approaches, the fish acquire a humpback and protuberant jaw. After spawning, they die and their carcasses provide a feast for gatherings of mink, bears, and Bald eagles.
      </p>
      <a href="#">See the Wildlife</a>
    </div>
  </body>

In your CSS, you use "." to target classes, but to target ids, you need to use "#".

#main-content {
  background-color: lightsteelblue;
}
