The 14 Content Blocks of HTML
A Content Block builds a Content Window with Topics and Paragraphs. Each Topic or Paragraph use a set of Text, Objects, and Forms, Breaks, and Connotations.
A Topic Block is either a Heading Block or a Title Block. Heading Blocks contribute to the document outline while Title Blocks don't. As a result, both Title Blocks and Paragraph Blocks follow an Heading Block in a Content Part, optionally through a Content Mix.
