< All the HTML Tags >

Definition:

The HTML <rb> tag is used within a <ruby> annotation to enclose the base text, which is the primary content for the ruby text.

Ruby annotations are a form of text annotation used primarily in East Asian typography to provide phonetic readings or translations of characters. The <rb> tag specifies the base text for which the annotations are provided. The enclosed content typically represents the original text, while additional tags like <rt> are used to provide the pronunciation or translation.

This tag is particularly valuable for languages such as Japanese, where complex characters may require supplementary reading information. When the browser renders this tag, it displays the base text prominently, usually adjacent to the ruby text, enhancing comprehension for readers. Using the `<rb>` tag within the `<ruby>` context aids in preserving the semantic structure of the annotated text.
