FAQ pages, navbar to footer: a page header, with or without a search field, over the answers as a searchable list, a topic grid, a split accordion or a master-detail pane. Four finished pages.
A section is one full-width band: a hero, a pricing table, a footer. A page stacks several of them into a finished screen, from the navbar to the footer. The sections are the parts, the page is one tested way to put them together.
