The primary div of a Page widget contains three other divs. What are their names and what are they used for?

What will be an ideal response?

The primary div contains three additional divs for the page header, content, and footer, by default. When you insert a new Page widget, you must provide a div ID to name and identify the page, such as home or services. The header div contains the heading of the page, such as Services. The content div contains the primary information for that particular page, such as information about the Gallery's services. The footer div contains copyright information for the home page and a home navigation button on subsequent pages.
