Which tag is used to define the body of the HTML document?

The tag is specifically designed to define the body of an HTML document. This tag encompasses all the content that is displayed on a web page, including text, images, links, and other elements. Everything a user sees when visiting a webpage resides within the body tag.

In contrast, the

tag is typically used to define the header section of the page, which often contains logos, navigation links, and other introductory content but does not represent the main content of the page. The

tag is used to specify the primary content of the document but is not responsible for containing all of the visible content; it works alongside the body tag. The

tag is utilized to define the footer section, which usually contains information like copyright details, links to privacy policies, or contact information, but it too does not represent the full body of the document.

Thus, the tag is the fundamental tag that encapsulates the entire displayable content of an HTML document.
