Question

我尝试制作简单的菜单，我的目标是让完整的col-md-2屏幕的背景颜色变黑（如图像-1），但是当文本/ radiobutton /等时。菜单结束，col-md-2的空屏幕的其余部分采用了正文的背景颜色（在图像-2中）而不是我的div的背景颜色。虽然我分别在我的身体背景颜色后面提到了<div>的背景颜色。这是我的代码：

<!DOCTYPE html>

  <head>
    <link data-require="bootstrap-css@3.3.6" data-semver="3.3.6" rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.css" />
    <style>
      .col-vh {
        background-color: #000;
        height: 100vh;
      }
    </style>
  </head>

  <body>
    <div class="container">
      <div class="row">
        <div class="col-md-2 col-vh">

向列中添加100vh，它应该是视口的100％。 See this plunker。
