Note/InfoThe <ruby> tag is a new tag added in HML5.
HTML5 <ruby> tag
The <ruby> tag specifies a ruby annotation to display the pronunciation of languages spoken in countries like China, Hong Kong, Japan, Macau, Mongolia, North Korea, South Korea & Taiwan.
This is an extra information about the meaning of these languages.
A <ruby> tag is often used with <rt> and <rp> tag.
The <rt> tag actually holds the meaning of the pronunciation.
While the <rp> tag is used to show a text to the browser if that browser does not support the ruby annotations.
