Chapter 3.5. Inline Formatting

Following table lists all elements that are supported for inline text formatting. Other HTML elements and attributes may work as well, but only the elements and attributes listed below are known to be supported for interactive and print output. The last column gives hints on how the elements should be used.

span
class, id, title
A span element can be used to
  1. Assign an inline-style
  2. Create a footnote (see Chapter 3.9, Footnotes)
  3. Create an index entry (see Chapter 3.10, Index Terms)
A span element should always have a class attribute. The value of the class attribute has to be the ID of an inline-style. Note that a span element without any attributes may be removed during export.
By adding an id attribute to a span element (and optionally a title attribute), the span element can be referenced by a link as described in Section 3.4.2, “Referencing Figures, Tables and other Content”.
