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

Bummer!

Inside the media query, select the list items inside the gallery and add a width of 28.3333%.

Bummer! Be sure to set the width of gallery list items to 28.3333% when the browser is wider than 480px.

ive done this, could someone type out the FULL correct code nothing seems to work.

css/main.css
@media screen and (min-width: 480px) {

}
#primary {
  width: 50%;
float: left;
}

#secondary {
  width: 40%;
  float: right;
}

  /*****************
3 + 5 = 15
100%-15% = 85%
85 / 3 = 28.333333333333
******************/

  /*****************
PAGE: PORTFOLIO
******************/

#gallery li {
  width 28.3333%;
}

#gallery li:nth-child(4n) {
  clear: left;
}
  /*****************
PAGE: ABOUT
******************/
.profile-photo {
  float: left;
  margin: 0 5% 80px 0;
}

} 
@media screen and (min-width: 660px) {

    /*****************
HEADER
******************/

  nav {
    background: none;
    float: right;
    font-size: 1.125em;
    margin-right: 5%;
    text-align: right;
    width 45%;
  }

  #logo {
    float: left;
    margin-left: 5%;
    text-align: left;
    width: 45%;
  }

  h1 {
    font-size: 2.5em;
  }

  h2 {
    font-size: 0.825em;
    margin-bottom: 20px;
  }

  header {
    border-bottom: 5px solid #599a68;

You have to write your code inside the media query

@media screen and (min-width: 480px) {
#gallery li {
  width: 28.3333%;
}
}
#primary {
  width: 50%;
float: left;
}

#secondary {
  width: 40%;
  float: right;
}

  /*****************
3 + 5 = 15
100%-15% = 85%
85 / 3 = 28.333333333333
******************/

  /*****************
PAGE: PORTFOLIO
******************/


#gallery li:nth-child(4n) {
  clear: left;
}
  /*****************
PAGE: ABOUT
******************/
.profile-photo {
  float: left;
  margin: 0 5% 80px 0;
}


@media screen and (min-width: 660px) {}

    /*****************
HEADER
******************/

  nav {
    background: none;
    float: right;
    font-size: 1.125em;
    margin-right: 5%;
    text-align: right;
    width 45%;
  }

  #logo {
    float: left;
    margin-left: 5%;
    text-align: left;
    width: 45%;
  }

  h1 {
    font-size: 2.5em;
  }

  h2 {
    font-size: 0.825em;
    margin-bottom: 20px;
  }

  header {
    border-bottom: 5px solid #599a68;
    margin-bottom: 60px;
  }

}

it didnt work :/

all you're missing is the : after width

width: 28.3333;

I hope this helps
