我知道这对位置很容易：固定，但不幸的是我坚持支持IE 6.我怎么能这样做？我宁愿使用CSS来干净，但如果我必须使用Javascript，那不是世界末日。在我目前的实现中，我有一个<！>“浮动页脚<！>”;漂浮在主要内容区域之上并使用Javascript定位。我现在的实现即使使用Javascript也不是特别优雅，所以我的问题是：
- 有没有办法在没有Javascript的情况下执行此操作？
- 如果我必须使用Javascript，那么<！>是否很好<！>这个浮动页脚问题的解决方案？通过<！> quot; nice <！> quot;我的意思是可以跨浏览器工作的东西，不会使浏览器的资源过载（因为它必须经常重新计算），并且优雅/易于使用（即编写类似
new FloatingFooter("floatingDiv")的东西会很好。）
我猜想没有超级简单的解决方案可以满足上述所有要求，但是我可以构建的东西会很棒。
最后，只是一个更普遍的问题。我知道这个问题很难解决，那么其他UI替代方案是什么，而不是在每个页面的底部都有页脚内容？在我的特定网站上，我用它来显示步骤之间的转换。还有其他方法吗？
解决方案
这可能对你有用。它适用于IE6和Firefox 2.0.0.17。试一试。我的页脚高度非常高，只是为了效果。您显然会将其更改为您需要的内容。我希望这适合你。

其他提示
如果您不想使用条件注释，以便可以将css放在单独的文件中，请使用!important。像这样：
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html>
<head>
<style>
html {
overflow-x: auto;
overflow-y: scroll !important;
overflow-y: hidden; /* ie6 value b/c !important ignored */
}
body {
padding:0;
margin:0;
height: 100%;
overflow-y: hidden !important;
overflow-y: scroll; /* ie6 value b/c !important ignored */
}
#bottom {
background-color:#ddd;
position: fixed !important;
position: absolute; /* ie6 value b/c !important ignored */
width: 100%;
bottom: 0px;
z-index: 5;
height:100px;
}
#content {
font-size: 50px;
}
</style>
</head>
<body>
<div id="bottom">
keep this text in the viewport at all times
</div>
<div id="content">
Let's create enough content to force scroll bar to appear.
Then we can ensure this works when content overflows.
One quick way to do this is to give this text a large font
and throw on some extra line breaks.
<br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/><br/>
<br/><br/><br/><br/><br/><br/><br/><br/>
</div>
</body>
</html>
$(function(){
positionFooter();
function positionFooter(){
if($(document).height() < $(window).height()){//Without the body height conditional the footer will always stick to the bottom of the window, regardless of the body height, $(document).height() - could be main container/wrapper like $("#main").height() it depend on your code
$("#footer").css({position: "absolute",top:($(window).scrollTop()+$(window).height()-$("#footer").height())+"px"})
}
}
$(window).scroll(positionFooter);
$(window).resize(positionFooter);
});
如果您将height 100%和overflow: auto添加到<html/>和<body/>标签，那么具有绝对位置的任何内容都将被修复。它最基本的是非常时髦与奇怪的滚动条，但可以调整到不错的结果。

}
.fixed

position: absolute;
bottom: 0px;

background: blue;
width: 100%;
}

如果页脚具有固定高度并且您知道它并且可以在CSS中对其进行硬编码，则可以这样做：
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html>
<head>
<style>
.content
{
position : absolute;
top : 0;
left : 0;
right : 0;
bottom : 50px; /* that's the height of the footer */
overflow : auto;
background-color : blue;
}
.footer
{
position : absolute;
left : 0;
right : 0;
bottom : 0px; /* that's the height of the footer */
height : 50px;
overflow : hidden;
background-color : green;
}
</style>
</head>
<body>
<div class="content">
everything from the page goes here
everything from the page goes here
everything from the page goes here
