无论有没有顶级导航,网站都有一个粘性页脚是很常见的。 Bootstrap可以轻松创建固定页脚,但没有这样的工具用于创建粘性页脚 - 这有很大的不同。
谷歌搜索这个问题将揭示数百(如果不是数千)开发人员有相同的问题,但没有好的答案。
具有讽刺意味的是,Bootstrap documentation页面本身具有粘性页脚以及引导样式和固定的顶部导航栏。这是所有自定义css,但不是框架的一部分。所以一个明显的路线是采取和重构他们的自定义样式,因为它显然在Bootstrap框架中运行良好,但这似乎比它应该更痛苦。
有关带Bootstrap顶部导航栏的示例页面以及不受欢迎的非粘性页脚,请参阅this plunkr。

当然,页脚应该具有响应性和跨浏览器友好性......

正如Schmalzy所指出的,答案可以在getbootstrap网站的示例部分找到here。
但该示例不包括顶级导航。对于带有粘性页脚的固定顶部导航,请参阅this plnkr或下面的代码。

/* Styles go here */
/* Sticky footer styles

/* The html and body elements cannot have any padding or margin. */

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 */

依赖于固定高度页脚的粘性页脚解决方案在响应式方法中失宠(其中页脚的高度通常在不同的断点处发生变化)。我见过的最简单的响应式粘性页脚解决方案涉及在顶级容器上使用display: table
,例如:

答案 2 :(得分:19)
最好的方法是执行以下操作:
HTML:Sticky Footer
CSS:CSS for Sticky Footer
HTML代码示例:
<div class="container">
<div class="page-header">
<h1>Sticky footer</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.</p>
<p>Use <a href="../sticky-footer-navbar">the sticky footer with a fixed navbar</a> if need be, too.</p>
</div>
<footer class="footer">
<div class="container">
<p class="text-muted">Place sticky footer content here.</p>
</div>
</footer>
CSS代码示例:
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;
}
另一个小调整可能会让它更完美(取决于你的项目),所以它不会影响移动视图的页脚。
@media (max-width:768px){ .footer{position:absolute;width:100%;} }
@media (min-width:768px){ .footer{position:absolute;bottom:0;height:60px;width:100%;}}

我一直在寻找一种简单的方法来使粘性页脚工作。
我刚申请class="navbar-fixed-bottom
&#34;它立即起作用
唯一要注意的是调整移动设备页脚的设置。
干杯!

对于那些正在寻找简单答案的人,你可以得到一个简单的工作示例from here:
html {
position: relative;
min-height: 100%;
}
body {
margin-bottom: 60px /* Height of the footer */
}
footer {
position: absolute;
bottom: 0;
width: 100%;
height: 60px /* Example value */
}
只需使用body
的{{1}}即可在内容和页脚之间添加空格。

我将详细阐述robodo在上述评论中所说的内容,一个非常快速和美观,更重要的是,响应(非固定高度)方法不涉及任何黑客攻击是使用flexbox。如果您不受浏览器支持,那么它就是一个很好的解决方案。
HTML
<body>
<div class="site-content">
Site content
</div>
<footer class="footer">
Footer content
</footer>
</body>
CSS
html {
height: 100%;
}
body {
min-height: 100%;
display: flex;
flex-direction: column;
}
.site-content {
flex: 1;
}

由于它位于bootstrap 3中,因此该站点将使用jQuery。所以解决方案也可以是以下内容,而不是尝试使用复杂的CSS:
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title></title>
<link href="css/bootstrap.min.css" rel="stylesheet" />
<style>
.my-footer {
border-radius : 0px;
margin : 0px; /* pesky margin below .navbar */
position : absolute;
width : 100%;
}
</style>
</head>
<body>
<div class="container-fluid">
<div class="row">
<!-- Content of any length -->
asdfasdfasdfasdfs <br />
asdfasdfasdfasdfs <br />
asdfasdfasdfasdfs <br />
</div>
</div>
<div class="navbar navbar-inverse my-footer">
<div class="container-fluid">
<div class="row">
<p class="navbar-text">My footer content goes here...</p>
</div>
</div>
</div>
<script src="js/jquery-1.11.0.min.js"></script>
<script src="js/bootstrap.min.js"></script>
<script type="text/javascript">
$(document).ready(function () {
var $docH = $(document).height();
// The document height will grow as the content on the page grows.
$('.my-footer').css({
/*
The default height of .navbar is 50px with a 1px border,
change this 52 if you change the height of your footer.
*/
top: ($docH - 52) + 'px'
});
});
</script>
</body>
</html>
不同的看法,希望它有所帮助。

轻松设置
position:absolute;
bottom:0;
width:100%;
到你的.footer
就这样做
答案 9 :(得分:1)
如果您的html具有(粗略)结构:
<div class="wrapper">
<div>....</div>
...
<div>....</div>
</div>
<div class="footer">
...
</div>
然后将页脚固定到屏幕底部的最简单的css是
html, body {
height: 100%;
}
.wrapper {
min-height: calc(100vh - 80px);
}
.footer {
height: 80px;
}
...页脚高度为80px。 calc
计算包装器的高度等于窗口的高度减去页脚高度(80px),超出.wrapper

对我有用的是添加相对于html标签的位置。
html {
min-height:100%;
position:relative;
}
body {
margin-bottom:60px;
}
footer {
position:absolute;
bottom:0;
height:60px;
}
