Yy-tooltip NPM

yy-tooltip

Simple vanilla-javascript tooltip replacement.

rationale

I wanted a simple replacement for the standard HTML tooltips that doesn't rely on stylesheets. It looks like the standard tooltip but accepts html and its style is more configurable. It attaches to the mouse position instead of the underlying div.

This was not designed to be as robust as other tooltip libraries (e.g., tooltip.js, tippy.js).

installation

npm i yy-tooltip

programmatic example

const Tooltip = require('yy-tooltip')

const element = document.getElementById('test')
new Tooltip(element, { title: '<div>First line</div><div>Second line</div>', styles: { background: 'black', color: 'white' }})
