Overview

The demo is a short FAQ with questions such as refunds and team discounts. Opening one section closes the previous one, and a checkbox switches to a mode where several sections can stay open. Each heading is a real button that announces whether its section is open. Motion: enter: 240 ms, cubic-bezier(0.2,0.8,0.2,1); exit: 180 ms, cubic-bezier(0.4,0,1,1). The shared easing curves live in one theme file, and each duration sits right next to its transition. With reduced motion turned on, the component changes state without movement and stays fully usable. Built with React 19 and TypeScript and Tailwind CSS 4, animated with plain CSS transitions (no animation library), with keyboard and screen reader behavior from Base UI. Light and dark themes come from CSS variables you can edit. Included: the component source, the accessible behavior it is built on, light and dark theme variables, a runnable demo page, and setup guides for people and for AI coding agents.
