Back to SnippetsFAQ accordion with native disclosure and expand-all controls
A progressive-enhancement FAQ using native details and summary, plus optional expand-all and collapse-all controls with live feedback.
HTMLCSSJavaScript
Receipt: four answers, native keyboard behavior, optional bulk controls.
What this is
Answers stay usable even when JavaScript does not.
Use this for concise FAQs, setup notes, policy explanations, or any supporting content visitors may reveal selectively.
The browser owns the core disclosure behavior; JavaScript only adds convenience controls.
Use it
- Paste the details elements into your page and replace the sample copy.
- Test each summary with keyboard and pointer before deciding whether the bulk controls are useful.
Make it yours
- Replace each question and answer without changing the native disclosure elements.
- Remove the bulk controls entirely if your FAQ is short.
Reuse contract
Supported environments
- Current Chrome, Edge, Firefox, and Safari
- Works without JavaScript
Security notes
- Render untrusted question and answer content as text or through a reviewed sanitizer.
- Do not hide required terms, pricing, or safety information inside a closed disclosure by default.
