  transition: max-height 0.35s ease, padding 0.35s ease;
}

Frequently Asked Questions

Do UIXDraft templates include FAQ accordion components?

Yes. The UI component templates include single-open, multi-open, nested and FAQ-specific accordion variants built in pure CSS and vanilla JS.

Is the accordion animation smooth?

Yes. The height animation uses max-height transition for smooth expand/collapse. The chevron icon rotates 180° to indicate state. No layout shift during animation.

Is the accordion keyboard accessible?

Yes. Each accordion trigger is a button element — focusable and activatable with Enter/Space. Screen readers announce the expanded/collapsed state via aria-expanded.

Can I have multiple accordions open at once?

Yes. Both single-open (only one panel at a time) and multi-open (any number of panels) variants are included. Switch between them with one JS configuration option.

Can I use accordions for a product FAQ page?

Yes. The FAQ accordion includes schema.org FAQPage structured data markup — Google can display the FAQ directly in search results as a rich snippet.
