why isnt my code working with the psuedo selector nth-child(n2)?

im suppose to clear: left and all my code seems correct, im lost.

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(4n) {
     clear: left
   }
}

Looks like there is no semi colon after "clear: left". :-)

I have tried it both ways, i initially had it with the semi-colon.

Since it's the last style, I don't think the lack of semi colon will effect the layout, but it's good practice anyway.

I'll see if I can find anything else...

You typed

li . (single dot) pseudo

It's a regular class from the parser's perspective

Change to

:nth-child(4)

look at the lesson again

I'm sure the code used is something like :nth-child(2n+1)

It means :nth-child([interval of]2n+[start at item]1)

would select 1,3,5...
