如何垂直对齐底部 [英] How to vertical align bottom

问题描述

考虑以下HTML和CSS:

Consider the following HTML and CSS:

HTML

<div class="eq">
    <span class="bar"></span>
    <span class="bar"></span>
    <span class="bar"></span>
    <span class="bar"></span>
    <span class="bar"></span>
</div>

CSS

.bar {
    background-color: green;
    width:15px;
    height:40px;
    display: inline-block;
    vertical-align: bottom;
    position: relative;
    bottom:0;
}

.eq {
    min-height:50px;
    border:1px solid blue;
}

我想垂直对齐:在蓝色div内的绿色条下面，但是似乎不起作用.有什么想法吗?

I want to vertically-align:bottom the green bars inside the blue div, however it doesn't seem to work. Any ideas?

推荐答案

我原本是将 .bar 更改为 display:table-cell 会起作用， (示例) ，但是这样做时，单元格的高度相同作为父元素.

I originally though that changing .bar to display:table-cell, would work, (example) however, in doing that, the cell takes the same height as the parent element.

想到的唯一解决方案是包装span元素:

The only solution that comes to mind is wrapping the span elements:

<div class="eq">
    <div id="bars">
    <span class="bar"></span>
    ...
    <span class="bar"></span>
    </div>
</div>

，然后使用以下CSS (示例) -可以.

and then using the following CSS (example) - it works.

.bar {
    background-color: green;
    width:15px;
    height:40px;
    display: inline-block;
    vertical-align:bottom;
}
#bars {
    display:table-cell;
    vertical-align:bottom;
}
.eq {
    min-height:100px;
    border:1px solid black;
    display:table;
}

基本上，我们将 display:table-cell 和 vertical-align:bottom 分配给包装元素 #bars .这适用于变化的高度. (示例)

Basically, we assign display:table-cell, and vertical-align:bottom to the wrapping element, #bars. This works for varying heights. (example)

请注意， .bar 元素之间的间距是因为它们是 inline-block 元素.如果要防止这种情况，请参见此 (示例) .

Note, that the spacing between the .bar elements is because of the fact that they are inline-block elements. If you want to prevent that, see this (example).
