My preview shows that my code is right. Nevertheless I got the message that my code is wrong... Help!

Can anyone tell me what is missing in my code?

index.html
<!DOCTYPE html>
<html lang="en">
<head>
    <title>Document</title>
    <link rel="stylesheet" href="style.css">
</head>
<body>
    <h2>My Favorite Things</h2>

    <ul class="favorite-things">
        <li>Kittens</li>
        <li>Rainbows</li>
        <li>Unicorns</li>
        <li>Sprinkles</li>
    </ul>

});

It took me a while to figure this one out, but it turns out the challenge has a very particular criteria about the answer beyond just valid code. Including:

  • the "prepend" method can take a variety of arguments, but the challenge expects an HTML string
  • using an intermediate variable is OK in practice, but the challenge expects the solution on one line
  • the challenge doesn't like any extra spacing in the HTML string

You might consider these unspecified requirements to be a "bug", and if so you may want to report it to the Support folks.
