Blog Post Card hover test failing

hey all, I havent been able to get my code to pass this test despite the hover working. I tried to 100% width trick that others were doing but no luck. Any ideas?

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <link rel="stylesheet" href="styles.css">
    <title>Blog Post Card</title>
</head>
<body>
    <div class="blog-post-card">
        <img src="https://cdn.freecodecamp.org/curriculum/labs/cover-photo.jpg" alt="Just some nerd's pc" class="post-img">
        <div class="post-content">
            <h2 class="post-title">
                tired of the tiny bite barks?
            </h2>
            <p class="post-excerpt">i teach you the way to make a chihuahua not hate you
            </p>
            <a class="read-more">Read More  
            </a>

        </div>





    </div>
</body>
</html>
body{
  background-color:teal
}

.blog-post-card{
  background-color:white;
  border-radius:30px;
  width: 100%;
  height: 100%;
  text-align:center;
  border-style:none;
}

.post-img{
   width: 100%;
  height: 100%;
  border-bottom:50px;
}

.post-content{
  padding:20px;
}

.post-title{
  color:blue;
  margin: 10px;
}
.post-exerpt{
  color:pink;
  margin: 10px;
}

.read-more {
  color:blue;
  background-color:pink;
  margin: 10px;
  padding: 10px;
  border-radius: 30px;
  display:inline-block;

}
.read-more:hover{
color:green;
border-style:none;
}

Please post a link to the challenge. Thank you.

whoops, sorry. didn’t know all the proper etiquette here https://www.freecodecamp.org/learn/responsive-web-design-v9/lab-blog-post-card/lab-blog-post-card

Your selector is fine, but it doesn’t look like you’re styling the background color as asked.
