How to Use

    Choose position and colors

    Four placements, background/text colors, radius, arrow.

    The tooltip fades in exactly as configured.

    Copy CSS and markup pattern

    class="has-tooltip" + data-tooltip="text" everywhere you need one.

Frequently Asked Questions

A ::after pseudo-element reads its text from content: attr(data-tooltip) and fades in on hover — so one CSS block powers every element with a data-tooltip attribute, no JavaScript.
