Why there is background-color in a project preview? There is no CSS declaration stating the color in the .wildlife class

Not in index.html, not in style.css

                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.

        <h3>From Tents to Resorts</h3>
        <p>
          Lake Tahoe is full of wonderful places to stay. You have the ability to sleep in the outdoors in a tent, or relax like a king at a five star resort. Here are our top three resorts:
        </p>
        <ul>
          <li><a href="#hotels">Lake Tahoe Resort Hotel</a></li>
          <li><a href="#resorts">South Lake Tahoe Resorts</a></li>
          <li><a href="#lodging">Tahoe Ski Resort Lodging</a></li>
        </ul>       
      </div>
      <div>
        <h3>Pack Accordingly</h3>
        <p>
          One of most important things when it comes to traveling through the great outdoors is packing accordingly. Here are a few tips:
        </p>
        <ol>
          <li>Bring layers of clothing</li>
          <li>Pack sunscreen</li>
          <li>Carry extra water just in case</li>
          <li>Pack light</li>
        </ol>

In "page.css" there is a rule for the "wildlife" class that includes background color:

page.css 
.wildlife {
    color: white;
    background-color: #434a52;
    padding: 18% 24%;
    margin-right: 0;
    margin-left: 0;
    margin-bottom: 60px;
}

I'd guess that this file was not included as one of the tabs since it is not needed to complete the challenge.
