About

Tooltips are essential UI patterns for decluttering interfaces, yet relying on JavaScript libraries like Tippy.js or Popper.js adds unnecessary bloat (often 10kb+) to your bundle size. For 95% of use cases, Pure CSS is superior in performance and maintainability.

This generator solves the complexity of positioning logic, z-index stacking contexts, and the notorious "CSS Arrow" geometry. Unlike standard generators that limit you to plain text via data-attributes, this tool offers a Rich HTML Mode strategy, enabling bold text, images, and icons inside your tooltips while maintaining accessible markup.

Frequently Asked Questions

The `data-tooltip` attribute method is extremely lightweight but cannot render HTML tags (like bold or italics). The browser renders the raw string. If you need icons, formatting, or images inside the tooltip, you must use the HTML Structure method which uses a nested child element.

CSS hover states are sticky on touch devices. To improve UX, use a `@media (hover: none)` query to move the tooltip text into a static block or ensure the trigger element is clickable to toggle visibility using the `:focus` pseudo-class alongside `:hover`.

Yes. The generated code for the HTML Structure method includes `role='tooltip'`. For the Attribute method, you should manually add `aria-label` to your trigger element matching the tooltip text for full WCAG compliance.

In the CSS Attribute method, the arrow is usually part of the same pseudo-element cluster. In the HTML Structure method, the arrow is a separate pseudo-element (`::after`), allowing for independent animation if you modify the generated CSS manually.
