HTML <ruby> Tag.

Example

漢 <rt> ㄏㄢˋ </rt>
</ruby> 
Execute Code

Definition and Usage

The <ruby> tag specifies a ruby annotation.

A ruby annotation is a small extra text, attached to the main text to indicate the pronunciation or meaning of the corresponding characters. This kind of annotation is often used in Japanese publications.

Use the <ruby> tag together with the <rt> and/or the <rp> tags: The <ruby> element consists of one or more characters that needs an explanation/pronunciation, and an <rt> element that gives that information, and an optional <rp> element that defines what to show for browsers that not support ruby annotations.


Browser Support

The numbers in the table specify the first browser version that fully supports the element.

Element Chrome Internet Explorer Firefox Safari Opera
<ruby> 5.0 5.5 38.0 5.0 15.0

Differences Between HTML 4.01 and HTML5

The <ruby> tag is new in HTML5.
