在div的CSS中试试这个:

display: table-cell;
vertical-align: middle;

我只是做了这个，它做了我想做的。

.align-middle {
  margin-top: 25%;
  margin-bottom: 25%;
}

现在我的页面是这样的

<div class='container-fluid align-middle'>
    content

 +--------------------------------+
 |                                |
 |  +--------------------------+  |
 |  |                          |  |
 |  |                          |  |
 |  |                          |  |
 |  |                          |  |
 |  |                          |  |
 |  +--------------------------+  |
 |                                |
 +--------------------------------+

HTML

<div class="row">
    <div class="col-xs-2 pull-bottom"
         style="height:100px;background:blue">
    </div>
    <div class="col-xs-8 pull-bottom"
         style="height:50px;background:yellow">
    </div>
</div>

CSS

.pull-bottom {
    display: inline-block;
    vertical-align: bottom;
    float: none;
}

不需要表和表单元格。利用变换可以很容易地实现。

例如:http://codepen.io/arvind/pen/QNbwyM

代码:

.child { height: 10em; border: 1px solid green; position: relative; } .child-content { position: absolute; top: 50%; left: 50%; -webkit-transform: translate(-50%, -50%); transform: translate(-50%, -50%); } <link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap.min.css" rel="stylesheet" /> <div class="row parent"> <div class="col-xs-6 col-lg-6 child"> <div class="child-content"> <div style="height:4em;border:1px solid #000">Big</div> </div> </div> <div class="col-xs-6 col-lg-6 child"> <div class="child-content"> <div style="height:3em;border:1px solid #F00">Small</div> </div> </div> </div>

从Bootstrap 4开始，Flex行为就得到了原生支持。在行div中添加d-flex align-items-center。您不再需要修改CSS内容。

简单示例:http://jsfiddle.net/vgks6L74/

<!-- language: html -->
<div class="row d-flex align-items-center">
  <div class="col-5 border border-dark" style="height:10em">  Big </div>
  <div class="col-2 border border-danger" style="height:3em"> Small </div>
</div>

用你的例子: http://jsfiddle.net/7zwtL702/

<!-- language: html -->
<div class="row d-flex align-items-center">
    <div class="col-5">
        <div class="border border-dark" style="height:10em">Big</div>
    </div>
    <div class="col-2">
        <div class="border border-danger" style="height:3em">Small</div>
   </div>
</div>

我详细阐述了zessx的答案，以便在不同屏幕尺寸上混合不同的列大小时更容易使用。

如果你使用Sass，你可以把这个添加到你的scss文件中:

@mixin v-col($prefix, $min-width) {
    @media (min-width: $min-width) {
        .col-#{$prefix}-v {
            display: inline-block;
            vertical-align: middle;
            float: none;
        }
    }
}

@include v-col(lg, $screen-lg);
@include v-col(md, $screen-md);
@include v-col(sm, $screen-sm);
@include v-col(xs, $screen-xs);

它生成以下CSS(如果你不使用Sass，你可以直接在你的样式表中使用):

@media (min-width: 1200px) {
    .col-lg-v {
        display: inline-block;
        vertical-align: middle;
        float: none;
    }
}

@media (min-width: 992px) {
    .col-md-v {
        display: inline-block;
        vertical-align: middle;
        float: none;
    }
}

@media (min-width: 768px) {
    .col-sm-v {
        display: inline-block;
        vertical-align: middle;
        float: none;
    }
}

@media (min-width: 480px) {
    .col-xs-v {
        display: inline-block;
        vertical-align: middle;
        float: none;
    }
}

现在你可以像这样在你的响应列上使用它:

<div class="container">
    <div class="row">
        <div class="col-sm-7 col-sm-v col-xs-12">
            <p>
                This content is vertically aligned on tablets and larger. On mobile it will expand to screen width.
            </p>
        </div><div class="col-sm-5 col-sm-v col-xs-12">
            <p>
                This content is vertically aligned on tablets and larger. On mobile it will expand to screen width.
            </p>
        </div>
    </div>
    <div class="row">
        <div class="col-md-7 col-md-v col-sm-12">
            <p>
                This content is vertically aligned on desktops and larger. On tablets and smaller it will expand to screen width.
            </p>
        </div><div class="col-md-5 col-md-v col-sm-12">
            <p>
                This content is vertically aligned on desktops and larger. On tablets and smaller it will expand to screen width.
            </p>
        </div>
    </div>
</div>
