Css 如何垂直对齐此div？

我的代码设置如下：

我想垂直对齐容器中间的蓝色按钮，但是容器没有固定的高度。

我如何才能做到这一点，最好只是在CSS

我知道我可以在jquery中这样做：

var halfOuterHeight = $('.jbe-result').height()/2,
    halfButtonHeight = $('.jbe-run').height()/2;

$('.jbe-run').css('margin-top', halfOuterHeight - halfButtonHeight)

---

但我宁愿不要

按钮不需要特殊容器，只需要CSS（上边距是按钮高度的一半）

---

嗯，还有一点工作要做

Html，我为文本和标题添加了周围的容器

<div class="jbe-result">
    <div class="jbe-whatever">
    <h3>text goes here which could be quite long winded which will push the height of the div higher</h3>
    <p>Date saved: 13-09-2013, 12:14 am</p>
        </div>
    <div class="jbe-run-container">
        <div class="jbe-run">Run</div>
    </div>


</div>

按钮应该是display:inline block并删除一些额外的属性：

.jbe-run{
    padding:4px 10px;
    width:70px;
    color:#ffffff;
    font-size:12px;
    border-radius:4px;
    -webkit-border-radius:4px;
    display: inline-block;

}

更新： 需要将jbe结果显示属性设置为table而不是table row

---

清理一点：

这种方法需要一点工作，但是您可以通过将文本包装到一个名为

jbe content container

的div容器中，与

jbe run container

处于同一级别，删除

jbe run

类上的

float:right

来解决这个问题，重新排列标记，将

'jbe-content-container

放在

jbe-run容器之前，然后使用
display:inline block
和
垂直对齐：中间对齐。我还必须通过移动一些边距和填充来进行调整

HTML

<div class="jbe-result">
    <div class="jbe-content-container">        
        <h3>small amount of text</h3>
        <p>Date saved: 13-09-2013, 12:14 am</p>
    </div>
    <div class="jbe-run-container">
        <div class="jbe-run">Run</div>
    </div>
</div>

<div class="jbe-result">
    <div class="jbe-content-container">
        <h3>text goes here which could be quite long winded which will push the height of the div higher</h3>
        <p>Date saved: 13-09-2013, 12:14 am</p>
    </div>
    <div class="jbe-run-container">
        <div class="jbe-run">Run</div>
    </div>
</div>

我更新了你的小提琴：


您还可以避免可能产生意外后果的浮动

.jbe-run{
    padding:4px 10px;
    width:70px;
    color:#ffffff;
    font-size:12px;
    border-radius:4px;
    -webkit-border-radius:4px;
    display: inline-block;

}

.jbe-run{
    margin-top: -10px;
    padding:4px 10px;
    width:70px;
    color:#ffffff;
    font-size:12px;
    border-radius:4px;
    -webkit-border-radius:4px;
    text-align: center;
    top: 50%;
    float: right;
    position: relative;
}

<div class="jbe-result">
    <div class="jbe-content-container">
