<ruby>
The
ruby
element allows one or more spans of phrasing content to be marked with ruby annotations.
Ruby annotations are short runs of text presented alongside base text, primarily
used in East Asian typography as a guide for pronunciation or to include other
annotations. In Japanese, this form of typography is also known as
furigana. Ruby text can appear on either side, and sometimes both sides, of the base text,
and it is possible to control its position using CSS. A more complete introduction
to ruby can be found in the
Use Cases & Exploratory Approaches for Ruby Markup document as well as in
CSS Ruby Module Level 1.
