See the Pen Cooltipz.css – Cool tooltips made from pure CSS by Bramus (@bramus) on CodePen. I especially like the fact that these are customisable using CSS Custom Properties. Here’s a few of them: :root { –cooltipz-bg-color: #fff; –cooltipz-text-color: #333; –cooltipz-border-radius: 5rem; } Installation per NPM: npm install cooltipz-css Cooltipz.css →
