Question

我正试图将容器流体放在它的父容器（body标签）中。以下是我的网页示例：

有问题的容器是我用黑色着色的容器，以便更好地识别。还有另外两个div：

 - The top one which is a (nav class="navbar navbar-inverse navbar-fixed-top")
 - The bottom one which is a (nav class="navbar navbar-inverse navbar-fixed-bottom")

问题是：我如何将容器流体（黑色）居中，始终位于页面中间？这个容器的内容会动态变化，我不能总是停留在中间（相同的边距顶部和底部）

谢谢你们。

编辑：根据要求，HTML和CSS：

HTML：

<body ng-controller="LanguageController as language">

<nav class="navbar navbar-inverse navbar-fixed-top" role="navigation">
<div class="container">
  <!-- 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="#language" aria-expanded="false" aria-controls="language">
      <span class="sr-only">Toggle navigation</span>
      <span class="icon-bar"></span>
      <span class="icon-bar"></span>
      <span class="icon-bar"></span>
    </button>
    <a class="navbar-brand" href="#"> {{ language.lblAppName }}</a>
  </div>
  <div class="navbar-collapse collapse" id="language">
    <div class="container vertical-center">
      <label> {{ language.lblSelectLanguage }} </label>
      <select ng-options="item for item in language.languages" ng-model="language.selectedLanguage" ng-change="language.changeLanguage()"></select>
      <button ng-click="language.editLanguage()">{{ language.lblEditLanguage }}</button>
    </div>
  </div>
   </div>
 </nav>


 <div id="corpus" class="container-fluid" ng-view="">
 </div>


<nav class="navbar navbar-inverse navbar-fixed-bottom" role="navigation">
 <div class="container-fluid">
  <!-- 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="#route" aria-expanded="false" aria-controls="route">
      <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="navbar-brand"> {{ language.lblFooter }} </div>
  </div>
  <div id="route" class="navbar-collapse collapse">
    <ul class="nav navbar-nav">
      <li class="active"><a href="#"> {{ language.lblMainPage }} </a></li>
      <li><a href="#">{{ language.lblFirstPage }}</a></li>
      <li><a href="#">{{ language.lblSecondPage }}</a></li>
      <li><a href="#">{{ language.lblThirdPage }}</a></li>
    </ul>
  </div>
  </div>
</nav>

CSS：

 body {
padding-top: 70px;
/* Required padding for .navbar-fixed-top. Remove if using .navbar-static-    top. Change if height of navigation changes. */
 }

.container {
 display: table;
}

.vertical-center {
 display: table-cell;
 padding-top: 1%;
 padding-left: 5%;
}

.vertical-center label.ng-binding{
color:grey;
}


div#corpus.container-fluid.ng-scope {
background-color:default;
}

div#mainDiv a.ng-binding {
color: black;
text-decoration: underline;
}

.top-buffer { 
margin-top:2%; 
}

基本上，这个问题一直是answered before。

.vertical-center {
  min-height: 100%;
  min-height: 100vh; 
  display: flex;
  align-items: center;
}

<div class="container-fluid vertical-center">
    Vertically centered in body.....
</div>
