HTML <rt> Tag

The <rt> tag is used to add annotations at the top and bottom of the text, inserted in the <ruby> tag. The <ruby> tag defines furigana (also called yomigana or ruby) annotations, pronunciation guide for relatively obscure characters in Japanese or East Asian languages.

The <rt> tag is one of the HTML5 elements.

The annotation placed in the <rp> tag contains a tip of pronunciation and translation of the basic text (hieroglyphs). Annotation is displayed in a small print above the hieroglyphs.


The <rt> tag comes in pairs; the closing tag isn’t required if it comes the last.


<!DOCTYPE html>
    <title>Title of the document</title>



The <rt> tag supports the Global Attributes and the Event Attributes.
