css - How to create a sticky footer that plays well with Bootstrap 3

With or without a top nav, it is very common for sites to have a sticky footer. Bootstrap has a facility to easily create fixed footers, but no such facility for creating sticky footers - there is a big difference.

Googling this question will reveal that hundreds if not thousands of developers have the same question but with no good answer.

Ironically, the Bootstrap documentation page itself has a sticky footer alongside bootstrap styling and a fixed top navbar. It's all custom css though, and not part of the framework. So an obvious route is to take and refactor their custom styling, since it obviously plays well within the Bootstrap framework, but that seems more painful than it ought to be.

See this plunkr for an example page with a Bootstrap top navbar, and an undesirable, non-sticky footer.

Problem:

(Thanks Softlayer - for the graphics)

A non-sticky footer is pretty ugly

Desired Solution:

A sticky footer is always at the bottom

Of course the footer should be responsive and cross-browser friendly as well...

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;
}
