Make footer stick to bottom of page using Twitter Bootstrap

Most of the above mentioned solution didn't worked for me. However, below given solution works just fine:

<div class="fixed-bottom">...</div>

just add the class navbar-fixed-bottom to your footer.

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

Update for Bootstrap 4 -

as mentioned by Sara Tibbetts - class is fixed-bottom

<div class="footer fixed-bottom">

As discussed in the comments you have based your code on this solution: https://stackoverflow.com/a/8825714/681807

One of the key parts of this solution is to add height: 100% to html, body so the #footer element has a base height to work from - this is missing from your code:

html,body{
    height: 100%
}

You will also find that you will run into problems with using bottom: -50px as this will push your content under the fold when there isn't much content. You will have to add margin-bottom: 50px to the last element before the #footer.
