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

Keeps saying "bummer", no idea why

This is what I've added for part 2 of the code challenge:

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

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

Am I missing something? It won't accept my code

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:28.33%;
  }
   #gallery li: nth-child(4n) { 
  clear:left;
  }

}

These code challenges are very picky about what they accept, that being said it is also for good reason (most syntaxs' are very specific). The error here has to do with your second ruleset #gallery li: nth-child(4n). You have an unnecessary space in your selector, right after li: the nth-child pseudo selector should come directly after the colon without any spaces.

So it should look like this:

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

I hope this was able to solve your issue! If you have any further questions about the subject, don't hesitate to ask here!

Thanks Ryan
