HTML <ruby> tag
HTML <ruby> tag is used to represent ruby annotations on the web page. Ruby annotations are useful if we want to show the pronunciation of East Asian characters like Chinese and Japanese Chinese.
The <ruby> tag enclosed one or more <rt> elements which give the pronunciation of ruby annotations and displays above the annotation characters. It can also contain <rp> (optional) element which is used as a fall-back parenthesis for the browser which does not support the ruby annotation.
HTML <ruby> tag can also be used to represent small annotation which is relevant to the main content, apart from East Asian language.
The <ruby> tag is new in HTML5.
