Header and footer are two terms used in web page design to refer to the top and bottom parts of the page, respectively:

Header:

The header is the top part of the web page. It usually contains elements such as the site logo, navigation menu, and perhaps some social links or search box. The header is an essential part of the design, as it helps visitors locate their place on the site and reach the main pages or basic sections easily.

Footer:

The footer is the bottom part of the web page. It usually contains additional information such as links to policies and terms pages, contact information, links to other related pages, and sometimes links to other websites or affiliates. The footer can also include information about copyright and design, and perhaps links to additional social media options.

Both headers and footers play an important role in the user’s web experience, helping to organize and facilitate navigation and providing basic information that visitors may need.
