Information types in HTML
HTML 4.0 (Strict) provides elements to denote certain types of
information. Although there is a default way each element type is presented,
it is possible to use style sheets to
change the presentation of any element. The types of information that can be
represented by HTML elements are:
  - Headings
- There are six levels of headings in HTML, which should be used to
      mark page or topic headings in order of their importance.
- Lists
- HTML provides two simple list types:
      
        - numbered lists (such as this one)
- unordered lists.
 It also provides for lists of terms and
      definitions 
- About the author
- A special element is provided for contact information about the
      author of an HTML page.
- Definitions
- These can be marked as an inline definition (i.e. defined in a normal
      paragraph) or in a list of terms and
      definitions. This list of information types is a definition list
      itself. It is also possible to use the value glossaryin
      therelattribute of a link, if that link is to a
      definition. In Amaya, the Links and Structure views include anyrelattributes on links.
- Quotations
- These can be marked inline or as blocks. In each case it is possible
      to mark the source of the quotation using the citeelement
      or theciteattribute
- Sample input, output, computer
  code
- Elements are provided for samples of computer code,
      variables, text to be entered and sample
      output.
- Abbreviations and acronyms
- Elements are available to denote abbreviations and acronyms.
- Insertions and Deletions
- There are elements to mark text that has been inserted, or should be
      deleted (This is useful for collaborative editing
      sub-editing).
- Emphasis
- HTML provides two levels of emphasis: ordinary emphasis and
      strong emphasis.
