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?

当前回答
当前版本的bootstrap似乎不再适用于这个函数了。如果你下载了他们的sticky-footer-navbar的例子,并在主体区域放置了大量的内容,footer将被向下推过视口的底部。它一点也不粘。

基于jk -fdrv的回答,我添加了一个.on('resize',函数(),以确保它在每种设备和每种分辨率上都能工作:
$(window).on('resize', function() {
if ($(document).height() <= $(window).height()) {
$('footer').addClass("navbar-fixed-bottom");
} else {
$('footer').removeClass("navbar-fixed-bottom");
}
});
参考官方的Boostrap3粘性页脚示例, 没有必要添加<div id="push"></div>, CSS更简单。
官方示例中使用的CSS为:
/* Sticky footer styles
-------------------------------------------------- */
html,
body {
height: 100%;
/* The html and body elements cannot have any padding or margin. */
}
/* Wrapper for page content to push down footer */
#wrap {
min-height: 100%;
height: auto;
/* Negative indent footer by its height */
margin: 0 auto -60px;
/* Pad bottom by footer height */
padding: 0 0 60px;
}
/* Set the fixed height of the footer here */
#footer {
height: 60px;
background-color: #f5f5f5;
}
以及基本的HTML:
<body>
<!-- Wrap all page content here -->
<div id="wrap">
<!-- Begin page content -->
<div class="container">
</div>
</div>
<div id="footer">
<div class="container">
</div>
</div>
</body>
您可以在粘脚示例的源代码中找到这个css的链接。
<!-- Custom styles for this template -->
<link href="sticky-footer.css" rel="stylesheet">

这是一个基于CSS的完全响应可变高度粘脚的解决方案。 优点:页脚允许可变高度,因为高度不再需要在CSS中硬编码。
body { display: -webkit-box; display: -webkit-flex; display: -moz-box; display: -ms-flexbox; display: flex; -webkit-box-orient: vertical; -webkit-box-direction: normal; -webkit-flex-direction: column; -moz-box-orient: vertical; -moz-box-direction: normal; -ms-flex-direction: column; flex-direction: column; min-height: 100vh; } body > * { -webkit-box-flex: 0; -webkit-flex-grow: 0; -moz-box-flex: 0; -ms-flex-positive: 0; flex-grow: 0; } body > nav + .container { -webkit-box-flex: 1; -webkit-flex-grow: 1; -moz-box-flex: 1; -ms-flex-positive: 1; flex-grow: 1; } /* Reset CSS and some footer styling. Only needed on StackOverflow */ body { padding: 50px 0 0; margin: 0; } footer { background-color: #f8f8f8; padding: 15px 0 5px; border-top: 1px solid #e7e7e7; } <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script> <link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet"/> <!DOCTYPE html> <!-- Fixed navbar --> <nav class="navbar navbar-default navbar-fixed-top"> <div class="container"> <div class="navbar-header"> <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#navbar" aria-expanded="false" aria-controls="navbar"> <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> <div id="navbar" class="collapse navbar-collapse"> <ul class="nav navbar-nav"> <li class="active"><a href="#">Home</a></li> <li><a href="#about">About</a></li> <li><a href="#contact">Contact</a></li> <li class="dropdown"> <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="false">Dropdown <span class="caret"></span></a> <ul class="dropdown-menu"> <li><a href="#">Action</a></li> <li><a href="#">Another action</a></li> <li><a href="#">Something else here</a></li> <li role="separator" class="divider"></li> <li class="dropdown-header">Nav header</li> <li><a href="#">Separated link</a></li> <li><a href="#">One more separated link</a></li> </ul> </li> </ul> </div><!--/.nav-collapse --> </div> </nav> <!-- Begin page content --> <div class="container"> <div class="page-header"> <h1>Responsive sticky footer of any height</h1> </div> <p class="lead">You can have a sticky footer of any height using this CSS.

这里是无前缀的SCSS(吞咽/咕噜声):
body {
display: flex;
flex-direction: column;
min-height: 100vh;
> * {
flex-grow: 0;
}
> nav + .container {
flex-grow: 1;
}
}
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">
<div class="navbar-header">
<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>
<div class="collapse navbar-collapse">
<ul class="nav navbar-nav">
<li class="active"><a href="#">Home</a></li>
<li><a href="#about">About</a></li>
<li><a href="#contact">Contact</a></li>
<li class="dropdown">
<a href="#" class="dropdown-toggle" data-toggle="dropdown">Dropdown <b class="caret"></b></a>
<ul class="dropdown-menu">
<li><a href="#">Action</a></li>
<li><a href="#">Another action</a></li>
<li><a href="#">Something else here</a></li>
<li class="divider"></li>
<li class="dropdown-header">Nav header</li>
<li><a href="#">Separated link</a></li>
<li><a href="#">One more separated link</a></li>
</ul>
</li>
</ul>
</div><!--/.nav-collapse -->
</div>
</div>
<!-- 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>
<p>Back to <a href="../sticky-footer">the default sticky footer</a> minus the navbar.</p>
</div>
<footer>
<div class="container">
<p class="text-muted">Place sticky footer content here.</p>
</div>
</footer>
</body>
</html>
CSS
/* Sticky footer styles
-------------------------------------------------- */
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;
}
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。
