我已经使用twitter引导框架很长一段时间了,他们最近更新到版本3!
我有麻烦让粘性页脚粘到底部,我已经使用了twitter bootstrap网站提供的启动器模板,但仍然没有运气,有什么想法吗?

下面是Sticky Footer的简化代码,因为他们一直在优化它,这是很好的:
HTML
<!DOCTYPE html>
<html lang="en">
<head></head>
<body>
<!-- Fixed navbar -->
<div class="navbar navbar-default navbar-fixed-top" role="navigation">
<div class="container">

<button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-collapse">
<span class="sr-only">Toggle navigation</span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
<a class="navbar-brand" href="#">Project name</a>

<div class="collapse navbar-collapse">
<ul class="nav navbar-nav">

<li><a href="#">Separated link</a></li>
<li><a href="#">One more separated link</a></li>
</ul>
</li>
</ul>
</div><!--/.nav-collapse -->

<!-- Begin page content -->
<div class="container">
<div class="page-header">
<h1>Sticky footer with fixed navbar</h1>
</div>
<p class="lead">Pin a fixed-height footer to the bottom of the viewport in desktop browsers with this custom HTML and CSS. A fixed navbar has been added with <code>padding-top: 60px;</code> on the <code>body > .container</code>.</p>

</div>
<footer>
<div class="container">
<p class="text-muted">Place sticky footer content here.</p>

CSS
/* Sticky footer styles

我想要一个灵活的粘性页脚,所以我才来这里。最重要的答案让我找到了正确的方向。
当前(10月16日2日)Bootstrap 3 css Sticky footer(固定大小)看起来像这样:
html {
position: relative;
min-height: 100%;
}
body {
/* Margin bottom by footer height */
margin-bottom: 60px;
}
.footer {
position: absolute;
bottom: 0;
width: 100%;
/* Set the fixed height of the footer here */
height: 60px;
background-color: #f5f5f5;
}
只要页脚的大小是固定的,body margin-bottom就会产生一个推力,让页脚可以坐进去。在本例中,两者都设置为60px。但如果页脚不是固定的,高度超过60px,它将覆盖你的页面内容。
使灵活:删除css正文边距和页脚高度。然后添加JavaScript来获取页脚高度,并设置body的marginBottom。这是通过setfooter()函数完成的。接下来添加事件监听器,用于页面第一次加载和调整大小时运行setfooter。注意:如果你的页脚有一个手风琴或其他触发大小变化的东西,而没有调整窗口的大小,你必须再次调用setfooter()函数。
运行代码片段,然后全屏演示。
function setfooter(){ var ht = document.getElementById("footer").scrollHeight; document.body.style.marginBottom = ht + "px"; } window.addEventListener('resize', function(){ setfooter(); }, true); window.addEventListener('load', function(){ setfooter(); }, true); html { position: relative; min-height: 100%; } .footer { position: absolute; bottom: 0; width: 100%; /* additional style for effect only */ text-align: center; background-color: #333; color: #fff; } body{ /* additional style for effect only not needed in bootstrap*/ padding:0; margin: 0; } <div> Page content <br> <br> line 3 <br> <br> line 5 <br> <br> line 7 </div> <footer id="footer" class="footer"> <div class="container"> <p class="text-muted">Footer with a long text, so that resizing, to a smaller screen size, will cause the footer to grow taller. But the footer will not overflow onto the main page.</p> </div> </footer>
我写我的简化粘脚代码与填充使用LESS。这个答案可能离题了,因为这个问题没有谈到填充,所以如果你有兴趣,可以查看这篇文章了解更多细节。
@footer-padding: 40px; // Set here the footer padding
@footer-inner-height: 150px; // Set here the footer height (without padding)
/* Calculates the overall footer height */
@footer-height: @footer-inner-height + @footer-padding*2;
html {
position: relative;
min-height: 100%;
}
body {
/* This avoids footer to overlap the page content */
margin-bottom: @footer-height;
}
footer{
/* Fix the footer on bottom and give it fixed height */
position: absolute;
bottom: 0;
width: 100%;
height: @footer-height;
padding: @footer-padding 0;
}
总结所有这些,只要记住一件事,除了footer以外的所有东西都应该有最小高度:100%或更少。
用Haml & Sass的话说就是:
Haml for app/view/layouts/application.html.haml
%html
%head
%body
Some body stuff
%footer
footer content
app/assets/stylesheet /application.css.sass
$footer-height: 110px
html
position: relative
min-height: 100%
body
margin-bottom: $footer-height
body > footer
position: absolute
bottom: 0
width: 100%
height: $footer-height
