<ruby> (Ruby Annotation)
This initially Microsoft-specific element, now part of HTML5, is used with the
rt
element to
create annotations or pronunciation guides for words and phrases. The base text should be
enclosed in a
<ruby>
tag; the annotation, enclosed in an
<rt>
tag, will appear as smaller
text above the base text. The
rp
element can be used to wrap content to delimit
ruby
text
for browsers that do not support this formatting.
