我正在寻找一种方法，垂直中心容器div在大屏幕内，并将其设置在页面的中间。
.jumbotron必须适应屏幕的全部高度和宽度。.container div的宽度为1025px，应该位于页面的中间(垂直居中)。
我希望这一页有超大屏幕适应屏幕的高度和宽度与容器垂直中心的超大屏幕。我怎样才能做到呢?
.jumbotron {
height:100%;
width:100%;
}
.container {
width:1025px;
}
.jumbotron .container {
max-width: 100%;
}

<div class="jumbotron">
<div class="container text-center">

<div class="row">

<div class="col-md-5 iPhone-features" style="margin-left:-25px;">

如果你使用Bootstrap 4，你只需要添加2个div:
.jumbotron{
height:100%;
width:100%;
}
<script src="https://code.jquery.com/jquery-3.2.1.slim.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/js/bootstrap.min.js"></script>
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css" rel="stylesheet"/>
<body>
<div class="jumbotron">
<div class="d-table w-100 h-100">
<div class="d-table-cell w-100 h-100 align-middle">
<h5>
your stuff...
</h5>
<div class="container">
<div class="row">
<div class="col-12">
<p>
More stuff...
</p>
</div>
</div>
</div>
</div>
</div>
</div>
</body>
类:d-table, d-table-cell, w-100, h-100和align-middle将完成这项工作
更新2021
Bootstrap 5仍然使用flexbox，因此垂直定心的方法与Bootstrap 4相同…
Bootstrap 4使用flexbox，所以垂直居中的方法更容易，不需要额外的CSS。
只需使用d-flex和align-items-center实用程序类。
<div class="jumbotron d-flex align-items-center">
<div class="container">
content
</div>
</div>

重点:垂直定心与高度有关。您试图居中的项的父容器必须具有已定义的高度。如果你想要页面的高度，在父级上使用vh-100或min-vh-100 !例如:
<div class="jumbotron d-flex align-items-center min-vh-100">
<div class="container text-center">
I am centered vertically
</div>
</div>
