Accordion feature

Nobody has claimed this yet.

SME are looking to bring back the "accordion" page template that existed in Percussion. For content not large enough to warrant a binder with multiple Info Details, the accordion feature is great for mobile users and those who will scan a web page for terms relevant to them.

Examples of accordions on other sites:
- https://www.cdc.gov/tularemia/statistics/index.html
- https://www.childrenssafetynetwork.org/webinars (Scroll to the header Archived Webinars)

Specific Mass.gov request:

> This is the page we are looking at: https://www.mass.gov/service-details/safe-sleep-information-for-parents-and-caregivers, which does not have enough information/text to warrant a binder.
>
> As you can see – it’s a lot of text, which we anticipate many people will read on their smartphones. In accordion style, visitors would get these potentially lifesaving tips in a much more succinct and easily digestible format. And with the accordion style we can call out the tips as headers, but people would have the choice of whether or not to expand for more information about a specific issue.

The issue names no repository files, tests, or entry points; start by reviewing the linked accordion examples and the referenced Mass.gov page. Define the page-template scope and acceptance criteria before implementation, since this request does not specify what code should change.
