Ruby Tag

<ruby> tag is introduced in HTML5. The HTML <ruby> tag is used for specifying Ruby annotations, which is used in East Asian typography.Use the <ruby> tag together with the <rt> and <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

<ruby> tag is supported in Internet Explorer 9, Firefox, Opera, Chrome and Safari.

Note: Internet Explorer 8 and earlier versions do not support the <ruby> tag.

Syntax

<ruby>

<rb>ruby base</rb>

<rp>(</rp>

<rt>ruby text</rt>

<rp>)</rp>

</ruby>
