This is a self-contained accordion component built with plain HTML, CSS, and JavaScript. Each question is a real button that toggles its answer panel and exposes state via aria-expanded for screen readers.
Click or activate a question header with the keyboard. The first activation expands the answer and sets aria-expanded to true. A second activation collapses it again and restores aria-expanded to false.
Yes. All CSS and JavaScript are inlined in this single HTML file. Open it directly in any modern browser with no network connection, package manager, or bundler required.
