Got problems on media queries after viewing the result can't display the header when u expand it from right to left

Here are the codes:

@media screen and (min-width: 480px) {
/*******************************
TWO COLUMN LAYOUT
******************************/  

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

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


/*******************************
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;
    margin-bottom: 60px;

Hi Lindley,

can we see your HTML? Also do you have a link to the site or are you making it local on your computer?

Only thing I can think of without seeing the code is maybe your header is collapsing due to no clearfix?

If so add this css:

.cf::before,
.cf::after {
content: " ";
display: table;
}

.cf::after {
clear: both;
}

and then in your HTML add this class to your header:

<div class="header cf">
<!-- Your Code Here -->
</div>

Good luck.
