The BODY tag is used to define the major content section of an HTML document.
HTML documents are typically divided into two major sections: the HEAD and the
BODY. The HEAD is where you place a lot of the META information and references
to supporting documents as well as optional client-side scripting.
The BODY is where you place the content for your web page. This includes text,
images and tables. Basically, anything that is visible to the visitor will be
defined in the BODY section.
