CSS CSS Selectors Advanced Selectors :nth Pseudo-Class Challenge - Pt. 2

What is Wrong With My CSS?

Here is what I am supposed to do: It looks like an <h1> made its way inside the parent body. Now our :nth-child selector no longer targets the desired combination of img child elements. Replace :nth-child with the pseudo-class that only targets a specific type of child element.

Now under here is what I did. What's wrong?

style.css
/* Write the CSS in the media query below */

@media (min-width: 607px) {
  img {
    float: left;
  }
  img:nth-child(3n+4) {
   clear: left;
  }
}
index.html
<!DOCTYPE html>
<html>
<head>
    <title>Selectors</title>
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link rel="stylesheet" href="page.css">
  <link rel="stylesheet" href="style.css">
</head>
<body>
   <h1>My Gallery</h1>
    <img src="thumb-forest.jpg" alt="">
    <img src="thumb-resort.jpg" alt="">
    <img src="thumb-trees.jpg" alt="">
    <img src="thumb-falls.jpg" alt="">
    <img src="thumb-view.jpg" alt="">
    <img src="thumb-sunset.jpg" alt="">
    <img src="thumb-lake.jpg" alt="">
    <img src="thumb-beach.jpg" alt="">
    <img src="thumb-bay.jpg" alt="">
    <img src="thumb-peaks.jpg" alt="">
    <img src="thumb-falls.jpg" alt="">
    <img src="thumb-resort.jpg" alt="">
</body>
</html>

Hey David,

The challenge is looking for nth-of-type() to replace nth-child. You can review this video starting at ~2:05

Keep Coding! :)

Am I doing it right? Because it still says I am doing it wrong.

/* Write the CSS in the media query below */

@media (min-width: 607px) {
  img {
    float: left;
  }
  img:nth-child-of-type(3n+4) {
   clear: left;
  }
}

As the code is, they are using img:nth-child, but they are looking for a different pseudo class ( not :nth-child). HINT: It's the title of the 2nd video in that module.
