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
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!

有位置的元素:绝对的;定位相对于 最近的定位祖先(而不是相对于 视口,像固定)。
所以你需要将父元素定位为相对或绝对元素,等等,并将所需元素定位为绝对元素,然后将bottom设置为0。
纯CSS,没有绝对定位,没有固定高度,跨浏览器(IE9+)
看看那个工作小提琴
因为正常的流程是“从上到下”,我们不能简单地要求#copyright div粘到他的父端的底部而没有某种绝对的定位,但如果我们想要#copyright div粘到他的父端的顶部,这将是非常简单的-因为这是正常的流程方式。
所以我们要利用这一点。 我们将改变div在HTML中的顺序,现在#copyright div在顶部,内容紧随其后。 我们还让内容div一直延伸(使用伪元素和清除技术)
现在只需要将视图中的顺序颠倒过来。这可以很容易地用CSS转换。
我们把容器旋转180度,现在:向上就是向下。(我们将内容反向,使其看起来正常)
如果我们想在内容区域内有一个滚动条,我们需要应用更多的CSS魔法。如图所示[在这个例子中,内容在标题下面-但它的想法是一样的]
* { margin: 0; padding: 0; } html, body, #Container { height: 100%; color: white; } #Container:before { content: ''; height: 100%; float: left; } #Copyright { background-color: green; } #Stretch { background-color: blue; } #Stretch:after { content: ''; display: block; clear: both; } #Container, #Container>div { -moz-transform: rotateX(180deg); -ms-transform: rotateX(180deg); -o-transform: rotate(180deg); -webkit-transform: rotateX(180deg); transform: rotateX(180deg); } <div id="Container"> <div id="Copyright"> Copyright Foo web designs </div> <div id="Stretch"> <!-- Other elements here --> <div>Element 1</div> <div>Element 2</div> </div> </div>
下面是一种方法,目的是使具有已知高度和宽度(至少大约)的元素浮到右边并停留在底部,同时作为其他元素的内联元素。它集中在右下角,因为您可以通过其他方法轻松地将它放置在任何其他角落。
我需要制作一个导航栏,在右下角有实际的链接和随机的兄弟元素,同时确保栏本身适当拉伸,而不破坏布局。我使用了一个“shadow”元素来占据导航栏的链接空间,并将其添加到容器子节点的末尾。
<!DOCTYPE html>
<div id="container">
<!-- Other elements here -->
<div id="copyright">
Copyright Foo web designs
</div>
<span id="copyright-s">filler</span>
</div>
<style>
#copyright {
display:inline-block;
position:absolute;
bottom:0;
right:0;
}
#copyright-s {
float:right;
visibility:hidden;
width:20em; /* ~ #copyright.style.width */
height:3em; /* ~ #copyright.style.height */
}
</style>
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
