Frequently Asked Questions

Why use <details> and <summary> in Markdown?

Long documentation and FAQs overwhelm readers. Collapsible accordions keep pages tidy and let readers explore only the sections they care about.

Why do my Markdown links fail inside a <details> block?

CommonMark requires an empty blank line after the opening <summary> tag. Our generator automatically inserts this required blank line to ensure Markdown renders flawlessly.

Can I nest accordions inside other accordions?

Yes! You can nest a <details> block inside another <details> block for multi-tiered documentation trees.
