Bigfoot is a jQuery plugin to help you create better footnotes and make them a lot easier to use.

Footnotes on the web can be a pain; you click a tiny number, get transported somewhere near the bottom of the page, find the footnote, and click on a link to go back where you can from.

This script makes that process painless by automatically detecting the footnote link and content. Then it turns the link into an easy-to-click button, and adds a popover when the the footnote button is clicked.

The script and default styles are built to work great on any size viewport; the popover is positioned on the top or bottom automatically (based on the relative amount of space), will update its location as the viewport changes size and will ensure that the popover never scrolls off screen. These elements make for a better user experience.

The tool is easy to install and use and comes with some options so you can make adjustments on your own.

• It sits on the optimal Y position between the baseline and descender line (the golden ratio point
