Use the faq accordion in Vanilla JS
Paste the markup where the component should appear. The small inline <script> wires up the interactive state with one delegated click listener — no framework needed.
Accessibility & customization
Each question is a <button> with aria-expanded and aria-controls pointing at its answer panel, so screen readers announce open/closed state and keyboard users can operate it with Enter or Space.
Every color, radius and dark-mode choice is baked into plain utility classes, so the copied code has no runtime dependency on this site.
