Bootstrap navbar-fixed-top not working

Question

I am using Bootstrap's navbar-top-fixed on my site but it doesn't seem to work. When I scroll down, it isn't fixed at the top.

Here is my HTML code:

<nav class="navbar navbar-default navbar-fixed-top" role="navigation">
  <div class="gdgt-menu">
    <!-- Brand and toggle get grouped for better mobile display -->
    <div class="navbar-header">
      <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1">
        <span class="sr-only">Toggle navigation</span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
      </button>
      <div class="gdgt-logo">
        <a class="navbar-brand" href="<?php echo get_site_url(); ?>" rel="bookmark">brand</a>
      </div>
    </div>

    <!-- Collect the nav links, forms, and other content for toggling -->
    <div class="nav-items collapse navbar-collapse" id="bs-example-navbar-collapse-1">
        <!--my menu is here-->
    </div><!-- /.navbar-collapse -->
  </div><!-- /.container-fluid -->
</nav>

And here is the CSS:

.gdgt-menu{
  padding-right: 10%;
  padding-left: 10%;
}

@media only screen and (min-width : 200px) and (max-width : 768px) {

  .navbar{
    margin-bottom: 0px !important;
  }

  .navbar-collapse {
    width: 100%;
  }

  .menu-header-container{
    width: 100%;
  }

  .gdgt-menu{
    padding-right: 0% !important;
    padding-left: 0% !important;
  }

  #bs-example-navbar-collapse-1 .current-menu-item a {
  padding-right: 100% !important;
}



}

@media only screen and (min-width : 200px) and (max-width : 768px) {

  .featured-content{
    width: 100%;
    margin-right: 0px !important;
    margin-left: 0px !important;
  }


}
@media only screen and (min-width : 768px) and (max-width : 1010px) {

  .gdgt-menu{
    padding-right: 0% !important;
    padding-left: 0% !important;
  }

  .nav-items{
    width: 85% !important;
  }

}


.nav-items{
    width: 70%;
    float: right;
}


.navbar{
    height: 60px;
    display: block;
    position: relative;
}

.menu{
  margin: 0px !important;

  padding-left: 0px !important;
}

.menu-header-container{
  float: right;
}

@media only screen and (min-width : 200px) and (max-width : 768px) {

  .menu-header-container{
    background-color: #2c3e50;
  }

  .menu li{
    width: 100% !important;
  }
}
.menu li{
  list-style-type: none;
  line-height: 60px;
  width: auto;
  float: left;
  transition: all 0.2s ease-in-out;
}

.menu li:hover{
  background-color: #34495e;
}

.menu a{
  color: #fff;
  text-decoration: none;
  padding-left: 20px;
  padding-right: 20px;
}

Any idea of what is causing this problem? I am not really sure why this is happening. However, I feel like the @media is causing this.

Please help :)

You are overriding bootstraps default positioning of the .fixed-top-navbar.

From bootsrap.css

.navbar-fixed-top,
.navbar-fixed-bottom {
  position: fixed; /* <-- Look here */
  right: 0;
  left: 0;
  z-index: 1030;
}

From your code:

.navbar{
    height: 60px;
    display: block;
    position: relative; /* <-- Oh dear */
}
