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.

This element only includes the global attributes.

• 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.

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>

Result

See the article about the <ruby> element for further examples.

If your browser does not support ruby annotations, the result looks like this instead:

• <ruby>
• <rt>
• <rb>
• <rtc>
