The HTML Ruby Fallback Parenthesis (<rp>
) element is used to provide fall-back parentheses for browsers that do not support display of ruby annotations using the <ruby>
element. One <rp>
element should enclose each of the opening and closing parentheses that wrap the <rt>
element that contains the annotation's text.

Attributes
This element only includes the global attributes.
Usage notes
- Ruby annotations are for showing pronunciation of East Asian characters, like using Japanese furigana or Taiwanese bopomofo characters. The
<rp>
element is used in the case of lack of<ruby>
element support; the<rp>
content provides what should be displayed in order to indicate the presence of a ruby annotation, usually parentheses.
Example
This example uses ruby annotations to display the Romaji equivalents for each character.
<ruby> 漢 <rp>(</rp><rt>Kan</rt><rp>)</rp> 字 <rp>(</rp><rt>ji</rt><rp>)</rp> </ruby>
CSS
body { font-size: 22px; }
The result looks like this in your browser:
The HTML above rendered by a browser without ruby support might look like this:
漢 (Kan) 字 (ji)
body { font-size: 22px; }
See the article about the <ruby>
element for further examples.
