<rp>: The Ruby Fallback Parenthesis element
BaselineWidely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
The<rp>HTML 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.
Try it
<ruby> 漢 <rp>(</rp><rt>kan</rt><rp>)</rp> 字 <rp>(</rp><rt>ji</rt><rp>)</rp></ruby>ruby { font-size: 2em;}Attributes
This element only includes theglobal 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.
Examples
Using ruby annotations
Without ruby support
If your browser does not support ruby annotations, the result looks like this instead:
漢 (Kan) 字 (ji)body { font-size: 22px;}Technical summary
