❓ FAQ

Single vs Multiple mode?

Single mode (Accordion) allows only one panel open at a time — opening a new panel closes others. Multiple mode (Collapsible) lets you open several panels simultaneously. Single is best for FAQ lists; Multiple works well for categorized content.

Does the generated code include JavaScript?

It's pure HTML+CSS using the checkbox/radio hack. No JavaScript needed, excellent browser compatibility. You can add JS enhancements if desired.

How to integrate into an existing project?

Copy the HTML and CSS code into your project. All classes are prefixed with accordion-xx to avoid conflicts. Customize accent color, border radius, and spacing to match your design.
