给定以下HTML:

< div id = "容器" > <!——这里的其他元素——> < div id =“版权”> 版权所有Foo网页设计 < / div > < / div >

我想把#copyright贴在#container的底部。我能在不使用绝对定位的情况下实现这一点吗?


当前回答

对于容器中只有一个子div的容器,可以使用表格单元格和垂直对齐方法,这种方法可以可靠地将单个div定位在父div的底部。

注意,使用table-footer-group作为前面提到的其他答案将破坏父表的高度计算。

#{容器 显示:表; 宽度:100%; 身高:200 px; } #{项 显示:表格单元; vertical-align:底部; } < div id = "容器" > <div id="item">单个底部项目</div> < / div >

其他回答

针对此特定场景的解决方案:

将inner放在父元素的底部。父节点的高度由它的“最高”兄弟节点的高度设置

设置:

我有一行与多个<div class="容器"> 这些<div class="container">在另一个<div class="supercontainer">中彼此相邻 每个<div class="container">都有3个内部div相互重叠:<div class="title">, <div class="content">, <div class="footer">

期望的结果:

所有<div class="container">的高度相同。高度没有在px中定义,它将是其中“最高”的高度。 <div class="title">应该在<div class="container">的顶部 <div class="content">应该放在<div class="title">下面 <div class="footer">应该放在<div class="container">的底部,而不与前面的内容重叠

如果你想让它“粘”在底部,不管容器的高度如何,那么绝对定位是要走的路。当然,如果版权元素是容器中的最后一个,它将始终位于底部。

你能详细说明一下你的问题吗?准确解释你想要做什么(以及为什么你不想使用绝对定位)?

如果你不知道子块的高度:

#{母公司 背景:绿色; 宽度:200 px; 身高:200 px; 显示:表格单元; vertical-align:底部; } .child { 背景:红色; vertical-align:底部; } < div id = "父" > < div class = "孩子" >的孩子 < / div > < / div >

http://jsbin.com/ULUXIFon/3/edit

如果你知道子块的高度,添加子块,然后添加padding-top/margin-top:

#{母公司 背景:绿色; 宽度:200 px; 身高:130 px; padding-top: 70 px; } .child { 背景:红色; vertical-align: 底; 身高:130 px; } < div id = "父" > < div class = "孩子" >的孩子 < / div > < / div >

也许这对某些人有帮助:你可以总是把一个div放在另一个div的外面,然后用负边距把它往上推:

<div id="container" style="background-color: #ccc; padding-bottom: 30px;">
  Hello!
</div>
<div id="copyright" style="margin-top: -20px;">
  Copyright Foo web designs
</div>

是的,你可以在没有绝对定位的情况下做到这一点,也可以不使用表(这与标记有关)。

演示 这是经过测试的工作在IE>7, chrome, FF &是一个非常容易添加到您现有的布局。

<div id="container">
    Some content you don't want affected by the "bottom floating" div
    <div>supports not just text</div>

    <div class="foot">
        Some other content you want kept to the bottom
        <div>this is in a div</div>
    </div>
</div>
#container {
    height:100%;
    border-collapse:collapse;
    display : table;
}

.foot {
    display : table-row;
    vertical-align : bottom;
    height : 1px;
}

它有效地做了浮动:底部会做的事情,甚至解释了@Rick Reilly的回答中指出的问题!
