nth-child selector

I am doing the code challenge. It asked me to create a new rule that targets the first 4 list items only. Set the font weight to bold.

It didn't go through....did my code wrong?

index.html 
<!DOCTYPE html>
<html>
<head>
    <title>Structural Pseudo-classes</title>
    <link rel="stylesheet" type="text/css" href="cc1-main-style.css">
    <link rel="stylesheet" type="text/css" href="style.css">
</head>
<body>
    <ul>
        <li>List item 1</li>
        <li>List item 2</li>
        <li>List item 3</li>
        <li>List item 4</li>
        <li>List item 5</li>
        <li>List item 6</li>
        <li>List item 7</li>
    </ul>
</body>
</html>
style.css 
/* Write your CSS below */
li:nth-child(even) {
  color: white;
  background-color: black;
}

li:nth-child(3n) {
  background-color: #ff6347;
}

li:nth-child(4n) {
  font-weight: bold;
}

li:nth-child(4n) only selects every 4th list item. It's really hard to wrap your head around, so I strongly encourage you to learn more about this.

Instead of explaining it, read this css-tricks article

The answer you want is li:nth-child(-n+4)

Your value 4n targets every fourth li element. Instead you are want to target all 4 of the first 4 elements.

You can do this by using -n + 4.

Learn more about the :nth-child pseudo selector on MDN's page.
