Features pages, navbar to footer: a page header, then the product toured band by band, bentos, tab rails, row lists and live windows, closed by proof and a call to action. Two 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.
