clear: left; Every Fourth Item

I am taking a coding challenge and I keep getting this code wrong. It looks like this:

@media screen and (min-width: 480px) {

gallery li {

width: 28.3333%; }

gallery li:nth-child(4) {

clear: left; } }

I am not seeing what I am missing. When I compare this code to the code I entered in workspaces, I don't see a difference.

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;
  }



}

this worked for me

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

From what I gather, #gallery li:nth-child(4) will only select the list items that are the 4th child of the #gallery div. So in this case, that would just be one list item. The an+b syntax makes it a cycle: http://www.w3schools.com/cssref/sel_nth-child.asp
