To get a footer that sticks to the bottom of your viewport, give it a fixed position like this:

footer {
position: fixed;
height: 100px;
bottom: 0;
width: 100%;
}

Bootstrap includes this CSS in the Navbar > Placement section with the class fixed-bottom. Just add this class to your footer element:

<footer class="fixed-bottom">

Add this:

<div class="footer navbar-fixed-bottom">

EDIT: class navbar-fixed-bottom has been changed to fixed-bottom as of Bootstrap v4-alpha.6.

Add z-index:-9999; to this method, or it will cover your top bar if you have 1.

Add fixed-bottom:

<div class="footer fixed-bottom">

You can do this by wrapping the page contents in a div with the following id styling applied:

<style>
#wrap {
min-height: 100%;
height: auto !important;
height: 100%;
margin: 0 auto -60px;
}
</style>


<div id="wrap">
<!-- Your page content here... -->
</div>

Worked for me.

Another solution :

You can use "min-height: 80vh;".

This allows you to set the minimum height, using the viewport height.

Example with bootstrap :

<style>
main {
min-height: 80vh;
height: auto !important;
height: 100%;
margin: 0 auto -60px;
}
</style>


<main class="container">
<!-- Your page content here... -->
</main>
<footer class="footer navbar-fixed-bottom">
<!-- Your page footer here... -->
</footer>
