HTML <ruby> Tag

The HTML <ruby> tag is used for specifying Ruby annotations.

The <ruby> tag is written as <ruby></ruby> with the base text and ruby annotations enclosed between the start and end tags. Modern standards recommend placing the base text directly inside the ruby element followed by the <rt> tag.

Event handler content attributes enable you to invoke a script from within your HTML. The script is invoked when a certain "event" occurs. Each event handler content attribute deals with a different event.

Most event handler content attributes can be used on all HTML elements, but some event handlers have specific rules around when they can be used and which elements they are applicable to.

For more detail, see HTML event handler content attributes.
