Getting Started

Compiled and production-ready code can be found in the dist directory. The src directory contains development code.

1. Include Sticky Footer on your site.

<script src="dist/js/sticky-footer.js"></script>

2. Add the markup to your HTML.

<div data-sticky-wrap>
	Body content
</div>
<div data-sticky-footer>
	Footer content
</div>

Add the data-sticky-wrap attribute to a parent <div> that contains all of your page content. Add the data-sticky-footer attribute to the parent <div> that contains all of your footer content.

3. Initialize Sticky Footer.

<script>
	stickyFooter.init();
</script>

In the footer of your page, after the content, initialize Sticky Footer. And that's it, you're done. Nice work!

Installing with Package Managers

You can install Sticky Footer with your favorite package manager.

  • NPM: npm install cferdinandi/sticky-footer
  • Bower: bower install https://github.com/cferdinandi/sticky-footer.git
  • Component: component install cferdinandi/sticky-footer

Working with the Source Files

If you would prefer, you can work with the development code in the src directory using the included Gulp build system. This compiles, lints, and minifies code.

Dependencies

Make sure these are installed first.

Quick Start

  1. In bash/terminal/command line, cd into your project directory.
  2. Run npm install to install required files.
  3. When it's done installing, run one of the task runners to get going:
    • gulp manually compiles files.
    • gulp watch automatically compiles files when changes are made and applies changes using LiveReload.

Options and Settings

Sticky Footer includes smart defaults and works right out of the box. But if you want to customize things, it also has a robust API that provides multiple ways for you to adjust the default options and settings.

Global Settings

You can pass callbacks into Sticky Footer through the init() function:

stickyFooter.init({
	selectorWrap: '[data-sticky-wrap]', // Selector for the wrap container (must use a valid CSS selector)
	selectorFooter: '[data-sticky-footer]', // Selector for the footer (must use a valid CSS selector)
	callback: function () {}, // Runs after the footer is stuck
});

Use Sticky Footer events in your own scripts

You can also call Sticky Footer events in your own scripts.

destroy()

Destroy the current stickyFooter.init(). This is called automatically during the init function to remove any existing initializations.

stickyFooter.destroy();

Browser Compatibility

Sticky Footer works in all modern browsers, and IE 9 and above.

Sticky Footer is built with modern JavaScript APIs, and uses progressive enhancement. If the JavaScript file fails to load, or if your site is viewed on older and less capable browsers, footers will simply float up against the content like they normally would.

How to Contribute

In lieu of a formal style guide, take care to maintain the existing coding style. Please apply fixes to both the development and production code. Don't forget to update the version number, and when applicable, the documentation.
