I have been looking for a way to add a footer to a Twitter Bootstrap 3 project I am working on.
What I want is for the footer to stick to the bottom of the page when the content is too short to fill out the screen, but get pushed down by content when the content does fill the screen.
All solutions I have found & tried so far, has either not worked, had the footer ALWAYS shown, or had the footer below the page, so it was only visible upon scrolling.
Thanks in advance!

There is difference between the "fixed" footer and "sticky" footer... you want the sticky footer.
Bootstrap 3
Use the standard "Sticky Footer" example. This method wraps the entire page content and pushes the footer down.
Here is a working demo: http://bootply.com/93620
<!-- Wrap all page content -->
<div id="wrap">
<!-- Fixed navbar -->
<div class="navbar navbar-default navbar-fixed-top">
...
</div>
<div class="container">
<!-- page content -->
</div>
</div>
<div id="footer">
Footer
</div>
/* 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 !important;
height: 100%;
/* 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;
}
Bootstrap 4
Because flexbox is default in Bootstrap 4, the "sticky" footer is easier.
<wrapper class="d-flex flex-column">
<nav>
</nav>
<main>
</main>
<footer>
</footer>
</wrapper>
body, wrapper {
min-height:100vh;
}
main {
flex:1;
}
CSS
/*Sticky footer*/
form , html, body {height: 100%;}
body{background-color:inherit;}
.wrapper{min-height:100%;height:auto!important;height:100%;margin:0 auto -4em}
.footer,.push{height:4em}
If you are not using ASP.NET then you may remove form{height:100%} from CSS
HTML
<body>
<div class="wrapper">
....Content....
<div class="push"></div>
</div>
<div class="footer">
<div class="container">
<hr />
<span>copyright 2014 | menelabs</span>
</div>
</div>
</body>
These days almost all browsers support viewport units. So used it to have sticky footer. It worked for me.
You can check viewport support here.
Adjust min-height for desired footer position when there is no content.
#main {
min-height: 70vh;
}<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" rel="stylesheet"/>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script src="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/js/bootstrap.min.js"></script>
<div id="header" class="bg-secondary">Header: Sticky footer example</div>
<div id="main" class="bg-light">
<!-- Nav tabs -->
<ul class="nav nav-tabs">
<li class="nav-item">
<a class="nav-link active" data-toggle="tab" href="#home">Home</a>
</li>
<li class="nav-item">
<a class="nav-link" data-toggle="tab" href="#menu1">Menu 1</a>
</li>
<li class="nav-item">
<a class="nav-link" data-toggle="tab" href="#menu2">Menu 2</a>
</li>
</ul>
<!-- Tab panes -->
<div class="tab-content">
<div class="tab-pane container active" id="home">
<h4>Home (Less content)</h4>
<p>Content 1: Lorem ipsum, or lipsum as it is sometimes known, is dummy text used in laying out print, graphic or web designs.</p>
</div>
<div class="tab-pane container fade" id="menu1">
<p>No content<p>
</div>
<div class="tab-pane container fade" id="menu2">
<h4>Menu 2 (More content)</h4>
<p>Content 1</p>
<p>Content 2</p>
<p>Content 3</p>
<p>Content 4</p>
<p>Content 5</p>
<p>Content 6</p>
</div>
