我正在设计一个带有导航栏的网站，后面是两列。由于某些原因，导航栏显示在顶部，左侧和右侧，尽管我没有添加任何这些属性。

导航栏和两列应该具有相同的宽度，当前情况并非如此：

      font-family: 'Open Sans', sans-serif;
      src: url('https://fonts.googleapis.com/css?family=Open+Sans') format('woff');
    }
    
    html {
      min-height: 100%;
    }
    
    body {
      font-family: 'Open Sans', sans-serif;
    }
    
    .nav {
      background-color: rgba(0, 0, 0, 0.75);
      height: 50px;
      width: 100%;
    }
    
    .nav a {
      float: left;
      color: #f2f2f2;
      padding: 14px;
      text-decoration: none;
      font-size: 17px;
      margin: 0;
    }
    
    .nav a:hover {
      text-shadow: 0px 0px 20px #ffffff;
    }
    
    .nav a:active {
    color: black;
    }
    
    .nav-right {
      float: right;
    }
    
    .nav img {
      float: left;
      width: 40px;
      height: 40px;
      line-height: 4em;
      margin-left: 10px;
      margin-top: 5px;
      margin-bottom: 5px;
    }
    
    .column {
      float: left;
      width: 50%;
    }
    .row:after {
      content: "";
      display: table;
      clear: both;
      width: 100%;
    }
    
    #hero-image {
      max-width: 50vw;
    }

我更新了您的样式，使之成为符合当今标准的正确CSS编码。Flex布局，描述性HTML5标记等。您可以在代码中找到更多注释。
