我通常熟悉使用css刷新页脚的技术。
但是我在将这种方法用于Twitter引导时遇到了一些麻烦，很可能是因为Twitter引导本质上是响应式的。使用Twitter引导，我不能得到页脚冲洗到页面底部使用上述博客文章中描述的方法。

你可以使用jQuery来处理这个问题:
$(function() {
/**
* Read the size of the window and reposition the footer at the bottom.
*/
var stickyFooter = function(){
var pageHeight = $('html').height();
var windowHeight = $(window).height();
var footerHeight = $('footer').outerHeight();
// A footer with 'fixed-bottom' has the CSS attribute "position: absolute",
// and thus is outside of its container and counted in $('html').height().
var totalHeight = $('footer').hasClass('fixed-bottom') ?
pageHeight + footerHeight : pageHeight;
// If the window is larger than the content, fix the footer at the bottom.
if (windowHeight >= totalHeight) {
return $('footer').addClass('fixed-bottom');
} else {
// If the page content is larger than the window, the footer must move.
return $('footer').removeClass('fixed-bottom');
}
};
// Call when this script is first loaded.
window.onload = stickyFooter;
// Call again when the window is resized.
$(window).resize(function() {
stickyFooter();
});
});

这是用Twitter Bootstrap和新的navbar-fixed-bottom类的正确方法:(你不知道我花了多长时间寻找这个)
CSS:
html {
position: relative;
min-height: 100%;
}
#content {
padding-bottom: 50px;
}
#footer .navbar{
position: absolute;
}
HTML:
<html>
<body>
<div id="content">...</div>
<div id="footer">
<div class="navbar navbar-fixed-bottom">
<div class="navbar-inner">
<div class="container">
<ul class="nav">
<li><a href="#">Menu 1</a></li>
<li><a href="#">Menu 2</a></li>
</ul>
</div>
</div>
</div>
</div>
</div>
</body>
</html>
使用这段代码在引导它的工作
<div class="navbar fixed-bottom">
<div class="container">
<p class="muted credit">Footer <a href="http://google.com">Link</a> and <a
href="http://google.com/">link</a>.</p>
</div>
</div>
HTML
<div id="wrapper">
<div id="content">
<!-- navbar and containers here -->
</div>
<div id="footer">
<!-- your footer here -->
</div>
</div>
CSS
html, body {
height: 100%;
}
#wrapper {
min-height: 100%;
position: relative;
}
#content {
padding-bottom: 100px; /* Height of the footer element */
}
#footer {
width: 100%;
height: 100px; /* Adjust to the footer needs */
position: absolute;
bottom: 0;
left: 0;
}
发现这里的片段工作得很好
Html:
<div id="wrap">
<div id="main" class="container clear-top">
<p>Your content here</p>
</div>
</div>
<footer class="footer"></footer>
CSS:
html, body {
height: 100%;
}
#wrap {
min-height: 100%;
}
#main {
overflow:auto;
padding-bottom:150px; /* this needs to be bigger than footer height*/
}
.footer {
position: relative;
margin-top: -150px; /* negative value of footer height */
height: 150px;
clear:both;
padding-top:20px;
}
HenryW的答案很好，尽管我需要做一些调整才能让它按我想要的方式工作。特别地，下面也处理:
避免“跳跃性”页面加载首先标记不可见和设置在javascript可见 优雅地处理浏览器大小调整 此外，如果浏览器变得更小，页脚变得比页面大，设置页脚备份 高度函数调整
以下是这些调整对我有效的方法:
HTML:
<div id="footer" class="invisible">My sweet footer</div>
CSS:
#footer {
padding-bottom: 30px;
}
JavaScript:
function setFooterStyle() {
var docHeight = $(window).height();
var footerHeight = $('#footer').outerHeight();
var footerTop = $('#footer').position().top + footerHeight;
if (footerTop < docHeight) {
$('#footer').css('margin-top', (docHeight - footerTop) + 'px');
} else {
$('#footer').css('margin-top', '');
}
$('#footer').removeClass('invisible');
}
$(document).ready(function() {
setFooterStyle();
window.onresize = setFooterStyle;
});
