[ProsperousHeart]

Requirements for section as per #63:

1. Since these links are not going external & will stay on the single page, need to set URL in the main project to the section on the page
2. determine what model (if any) is required for the project app (site section)
3. build the HTML view & model (as needed)
4. add CSS for the section
5. once ready, leave in REVIEW (see board) until other sections are added to confirm interactivity
6. ensure hamburger menu when mobile
