Morphing tooltip

A CSS-first tooltip that begins as a small status dot and expands into an explanatory bubble. The native trigger stays linked to the description, and focus users receive the same content and spatial treatment as pointer users.

Implementation field notes

Use morphing tooltip confidently.

The preview and source are only the starting point. Use these notes to decide where the component fits, preserve its accessibility contract, and verify the adapted result.

Good fit for

  • Status explanations
  • Inline help
  • Feature education

This tooltips pattern works best when its purpose is clear in the surrounding page hierarchy.

Accessibility contract

  • The trigger is a native button linked with aria-describedby.
  • Tooltip content appears on hover and focus-within.
  • Reduced motion changes size instantly.

Integration plan

  1. Copy the standalone HTML and scoped CSS into an isolated page.
  2. Adapt tooltip color, accent color, text color, corner radius through the Inspector.
  3. Keep the semantic markup intact while replacing the sample content.
  4. Review the result at 375, 768, 1024, and 1440 pixels before shipping.
