As explained in the introduction, Popper has a sole goal: position elements. That's why we call it a "positioning engine" and not a "tooltip library".
If you are looking for a ready to use library to create beautiful tooltips and popovers, you don't want to miss out on Tippy.js.
Tippy leverages Popper to position its tooltips and popovers, but adds a whole set of functionalities you'd expect from a tooltip library. It provides awesome transitions, great accessibility, built-in themes, TypeScript types and more.
You can start using it right now in your project by visiting its official website here.
