Create a selector that targets a <div> that is an adjacent sibling of a <div>. Set a top margin of 15px.

I wrote: h2 + div { margin-top: 15px; }

I did an adjacent sibling , but it is wrong ?

style.css 
/* Complete the challenge by writing CSS below */

header img{
 margin: 20px;
}

.main-content p{
  font-weight: bold;     /*文字粗細*/
}

h2 + div {
margin-top: 15px; 
}
index.html 
<!DOCTYPE html>
<html>
  <head>
    <title>Combinators Challenge</title>
    <link rel="stylesheet" href="page.css">
    <link rel="stylesheet" href="style.css">
  </head>
  <body>
    <header>
      <h1>Lake Tahoe, California</h1>
      <img src="mtn-landscape.jpg" alt="foggy mountains">
    </header>
    <div class="main-content">
      <h2>Journey Through the Sierra Nevada Mountains</h2>
      <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>
    </div>
    <div>
      <h2>From Tents to Resorts</h2>
      <span>Lake Tahoe is full of wonderful places to stay.
        <span>Sleep in the outdoors in a tent, or relax at a resort.</span>
      </span>
    </div> 
  </body>
</html>

You used the right operator but you need to give 2 div elements as your selector to tell CSS that it needs to look for the 2 div elements in the same place in the document tree. Replace the h2 in your selector with another div.

The adjacent sibling combinator (+) separates two selectors and matches the second element only if it immediately follows the first element, and both are children of the same parent element.

so it will be div + div { margin-top: 15px; }
