Did you clear the left side of the images? Like this: 'clear: left'. img:nth-child (3n+4) {clear: left;} what's wrong?

I am not able to find the mistake here. Help please!!!

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>
    <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>

Hi there -

You've got the code right - I believe it just has a problem with the space between "nth-child" and the parameter. Without that space, it passes for me.

why cant you do it like this? why do you need to seperate the img tags?

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