What is it?

An open-source library for creating tooltips on web pages in a nice neat fashion.

What do we use it for?

For icons and buttons where the user can hover over the button or icon to show the tooltip. Tippy.js is useful for this, as displaying tooltips in a neat way on any given page can be tricky, so this library helps in making the tooltips always look nice.
