An accordion is a user interface pattern that consists of vertically stacked sections where only one (or sometimes multiple) section can be expanded at a time. Each section has a clickable header that toggles the visibility of its hidden content, creating a clean, collapsible layout.

Accordion-style FAQs keep the page visually tidy and prevent information overload. Users can scan headings quickly, expand only the question they care about, and avoid scrolling through dozens of answers at once, resulting in a much better user experience and higher engagement.

Accordions excel for specifications/technical details, product features, pricing plan comparisons, shipping & returns policies, glossary terms, step-by-step instructions, team member bios, event schedules, and any content where users typically need just one section at a time.

Yes. Search engines can still crawl and index the hidden content (especially when implemented with proper semantic HTML), so you get the benefits of comprehensive information without hurting SEO.

When built correctly using native HTML details/summary elements or ARIA-compliant JavaScript, accordions are fully keyboard-navigable, screen-reader friendly, and work perfectly on touch devices. They’re actually one of the most accessible progressive-disclosure patterns available.
