CSS How to Make a Website Responsive Web Design and Testing Refactor the Layout

I can't see what's wrong with an answer I've given in a quiz (CSS)

I'm told: Bummer! Did you set "clear: left;" on every 4th child..?

After first typing this manually, I copied the css from my workspace, and I still get the error. I just can't see what's wrong here.

gallery li:nth-child(4) {

clear: left;

}

css/main.css
a {
  text-decoration: none;
}

#wrapper {
  max-width: 940px;
  margin: 0 auto;
}

#logo {
  text-align: center;
  margin: 0;
}

h1, h2 {
  color: #fff;
}

nav a {
  color: #fff;
}

nav a:hover {
  color: #32673f;
}

h1 {
  font-family: Changa One, sans-serif;
  font-size: 1.75em;
  font-weight: normal;
}

img {
  max-width: 100%;
}

#gallery {
  margin: 0;
  padding: 0;
  list-style: none;
}

#gallery li {
  float: left;
  width: 45%;
  margin: 2.5%;
  background-color: #f5f5f5;
  color: #bdc3c7;
}

nav ul {
  list-style: none;
  margin: 0 10px;
  padding: 0;
}

nav li {
  display: inline-block;
}

nav a {
  font-weight: 800;
  padding: 15px 10px;
}

.profile-photo {
  display: block;
  margin: 0 auto 30px;
      max-width: 150px;
  border-radius: 100%;
}

.contact-info {
  list-style: none;
  padding: 0;
  margin: 0;
  font-size: 0.9em;
}

.contact-info a {
  display: block;
  min-height: 20px;
  background-repeat: no-repeat;
  background-size: 20px 20px;
  padding: 0 0 0 30px;
  margin: 0 0 10px;
}

@media screen and (min-width: 480px) {
  #gallery li {
    width: 28.3333%;
  }


  #gallery li:nth-child(4) {
    clear: left;
  }
}

You almost had this - so close!

The question is asking you to clear EVERY 4th element, while the code you wrote selects ONLY the fourth child (and not child element 8, 12, etc.).

So what you really want is something like this.

@media screen and (min-width: 480px) {
  #gallery li {
   width: 28.3333%;
  }
  #gallery li:nth-child(4n+4) {
    clear: left;
  }
}

Keep up the good work!

Thanks! I Didn't notice this in the video, as I was busy typing code. And since the list only contained 5 items, nothing gave me a hint something was wrong :)
