Not sure what you have tried so far, but its pretty simple. Just do this: http://plnkr.co/edit/kmEWh7?p=preview

html, body {
height: 100%;
}


footer {
position: absolute;
bottom: 0;
}

最佳答案

The answer, as Schmalzy points out, can be found here in the examples section of the getbootstrap site.

But that example does not include a top nav. For fixed top nav with sticky footer, see this plnkr, or code below.

Style CSS:

/* Styles go here */


/* 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;
}




/* Custom page CSS
-------------------------------------------------- */
/* Not required for template or sticky footer method. */


.container {
width: auto;
max-width: 680px;
padding: 0 15px;
}
.container .credit {
margin: 20px 0;
}

Sticky footer solutions that rely upon fixed-height footers are falling out of favour in with responsive approaches (where the height of the footer often changes at different break points). The simplest responsive sticky footer solution I've seen involves using display: table on a top-level container, e.g.:

Since it's in bootstrap 3, the site will be using jQuery. So the solution could also be the following, instead of trying to play with complex 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>

A different take on it, hope it helps.

Kind regards.

The best way is to do the following:
HTML:Sticky Footer
CSS: CSS for Sticky Footer
HTML Code Sample:

<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 Code Sample:

    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;
}

Another little tweak might make it more perfect (depends on your project), so it will not affect footer on mobile views.

@media (max-width:768px){ .footer{position:absolute;width:100%;} }
@media (min-width:768px){ .footer{position:absolute;bottom:0;height:60px;width:100%;}}

easily set

position:absolute;
bottom:0;
width:100%;

to your .footer

just do it

I've been searching for a simple way to make the sticky footer works. I just applied a class="navbar-fixed-bottom" and it worked instantly Only thing to keep in mind it's to adjust the settings of the footer for mobile devices. Cheers!

For those who are searching for a light answer, you can get a simple working example 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 */
}

Just play with the body's margin-bottom for adding space between the content and footer.

I will elaborate on what robodo said in one of the comments above, a really quick and good looking and what is more important, responsive (not fixed height) approach that does not involve any hacks is to use flexbox. If you're not limited by browsers support it's a great solution.

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;
}

Browser support can be checked here: http://caniuse.com/#feat=flexbox

What worked for me was adding the position relative to the html tag.

html {
min-height:100%;
position:relative;
}
body {
margin-bottom:60px;
}
footer {
position:absolute;
bottom:0;
height:60px;
}

In case your html has the (rough) structure:

<div class="wrapper">
<div>....</div>
...
<div>....</div>
</div>
<div class="footer">
...
</div>

then the simplest css that fixes footer to the bottom of your screen is

html, body {
height: 100%;
}
.wrapper {
min-height: calc(100vh - 80px);
}
.footer {
height: 80px;
}

... where the height of the footer is 80px. calc calculates the height of the wrapper to be equal to the window's height minus the height of the footer (80px) which is out of the .wrapper
