HTML and CSS Reference
In-Depth Information
Note
• Other browsers do not position the ruby text element (
rt
) but instead move the
rt
content above the text it is associated with; thus, these browsers are not listed as
supporting
rt
. The purpose of the
rp
element is to show the grouping parentheses
in such nonsupporting browsers, so in some sense all browsers support this
element.

No Ruby
<rt> (Ruby Text)
This initially Microsoft-specific proprietary element, now part of HTML5 and XHTML 1.1,
is used within a
<ruby>
tag to create
ruby text
, or 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. Ruby parentheses
should be set with
<rp>
tags to provide fallback for browsers without ruby support.
