如何在div中垂直对齐元素?

哇，这个问题很受欢迎。这是基于对垂直对齐属性的误解。这篇优秀的文章解释了这一点:

理解垂直对齐，或者Gavin Kistner的“如何(不)垂直居中内容”。

“如何在CSS中居中”是一个很好的网络工具，它可以帮助您在不同的情况下找到必要的CSS居中属性。

简而言之(并防止链接腐烂):

Inline elements (and only inline elements) can be vertically aligned in their context via vertical-align: middle. However, the “context” isn’t the whole parent container height, it’s the height of the text line they’re in. jsfiddle example For block elements, vertical alignment is harder and strongly depends on the specific situation: If the inner element can have a fixed height, you can make its position absolute and specify its height, margin-top and top position. jsfiddle example If the centered element consists of a single line and its parent height is fixed you can simply set the container’s line-height to fill its height. This method is quite versatile in my experience. jsfiddle example … there are more such special cases.

我发现了一个新的解决方案，垂直对齐多个文本行在一个div使用CSS 3(我也使用bootstrap v3网格系统来美化UI)，如下所示:

.immediate-parent-of-text-containing-div {
    height: 50px;         /* Or any fixed height that suits you. */
}

.text-containing-div {
    display: inline-grid;
    align-items: center;
    text-align: center;
    height: 100%;
}

根据我的理解，包含元素的文本的直接父元素必须有一定的高度。

就在这个:

<div>
    <table style="width: 100%; height: 100%">
        <tr>
            <td style="width: 100%; height: 100%; vertical-align: middle;">
               What ever you want vertically-aligned
            </td>
        </tr>
    </table>
</div>

一个单元表内的div处理垂直对齐和向后兼容回石器时代!

几乎所有的方法都需要指定高度，但通常我们没有任何高度。

这里有一个css3的三行技巧，它不需要知道高度。

.element {
    position: relative;
    top: 50%;
    transform: translateY(-50%);
}

甚至在IE9中也支持它。

与其供应商前缀:

.element {
    position: relative;
    top: 50%;
    -webkit-transform: translateY(-50%);
    -ms-transform: translateY(-50%);
    transform: translateY(-50%);
}
