Question

我是CSS的新手，所以我尽力解决这个问题，但是我似乎陷入困境。

导航栏在桌面上工作正常，但是一旦屏幕调整大小并且下拉菜单被激活，子菜单就会显示与主菜单一致。看看jsfiddle：

子菜单在没有@media CSS的情况下工作正常，导航的CSS是：

#navigation {
    text-align: center;
    background: #464646;
    min-height: 40px;
    width: 100%;
    display: inline-block;
  }

  #navigation .btn-navbar {
    background: url('img/nav-collapse.png') no-repeat;
    border: none;
    border-radius: 0;
    box-shadow: none;
    height: 40px;
    margin: 0;
    padding: 0;
    width: 53px;
  }

  #navigation .caret {
    border-bottom-color: #fff;
    border-top-color: #fff;
    margin-top: 10px;
    margin-left: 5px;
  }

  #navigation ul {
    list-style-type: none;
    margin: 0;
    padding: 0;
    display: inline-block;
  }

  #navigation ul li {
    display: inline-block;
    float: left;
    position: relative;
  }

  #navigation ul li.active {
    background: #fff;
  }

  #navigation ul li:first-child a {
    border-left: 1px solid #333;
  }

  #navigation ul li a {
    border-right: 1px solid #333;
    color: #fff;
    display: block;
    padding: 10px 18px;
    text-decoration: none;
  }

  #navigation ul li.active a {
    color: #333;
  }

  #navigation ul li:hover a,
  #navigation ul li a:hover {
    background: #fff;
    color: #333;
  }

  #navigation ul li.active .caret,
  #navigation ul li:hover .caret,
  #navigation ul li a:hover .caret {
    border-bottom-color: #333;
    border-top-color: #333;
  }

  #navigation ul li:hover ul {
    left: -4px;
  }

  #navigation ul li ul {
    background: #FFF;
    border-bottom: 4px solid #EEE;
    border-right: 4px solid #EEE;
    border-left: 4px solid #EEE;
    left: -999em;
    width: 220px;
    padding-bottom: 5px;
    position: absolute;
    z-index: 2000;
  }

  #navigation ul li ul li {
    width: 100%;
  }

  #navigation ul li ul li a {
    border: none !important;
    color: #333333;
  }

媒体CSS是：

    body {
      padding-left: 0;
      padding-right: 0;
    }
    #navigation .container,

    }
    #content {
      padding: 20px 20px 10px;
    }
    .container {
      width: 100%;
    }
    #masthead,
    #masthead .container {
      height: auto;
    }
    #masthead .logo {
