The <ruby> tag is a semantic HTML element that represents small annotations usually used for showing the pronunciation of Japanese and East Asian characters. <ruby> can be used together with <rt> and/or <rp>.
The <ruby> tag entails one or more characters that require an explanation or pronunciation, the <rt> element provides the explanation or pronunciation, and the optional <rp> element provides what to show for browsers that lack support for annotations.
Syntax
<ruby><!-- Contents go here --></ruby>
<ruby> wraps around the text that needs annotation.
Example
This following example shows <ruby> being used with <rt> and <rp> tag:
<ruby> ゆきひろ まつもと <rp>(</rp><rt>Yukihiro Matsumoto</rt><rp>)</rp> </ruby>
