Simplify FAQ With Collapsible Design

I have a user guide, and I want to rework only its FAQ section. The text should be rewritten in clear, reader-friendly language while remaining accurate, but the main objective is to give the page a cleaner, more engaging look. I want each Q&A pair placed inside collapsible sections so the content feels lighter and users can scan it quickly without scrolling through long blocks of text.

Please keep technical jargon to a minimum, streamline each answer to its essentials, and lay out the collapsible structure in lightweight HTML (or another format you recommend that drops straight into a typical CMS). Any styling cues should be inline or noted in a brief CSS snippet so I can paste everything in one go.

Deliverables:
• A simplified, language-adapted FAQ section with collapsible markup.
• A short note explaining how to embed or style the collapsibles in a standard web page.
