The rp tag, or ruby parenthesis tag, is an HTML element used in conjunction with the ruby and rt tags to define the representation of the pronunciation of characters in ruby annotations. Ruby annotations are a way to provide additional information about the pronunciation of East Asian characters, typically used in languages such as Japanese. In this article, we will delve into the details surrounding the rp tag, including its usage, attributes, examples, and related tags.
I. Introduction
A. Definition of the rp tag
The rp tag is an inline HTML element that denotes the parentheses used by a browser that does not support the ruby annotation system. It provides a fallback for users where they might not see the ruby text by wrapping it in parentheses or another specified character.
B. Purpose of the rp tag in HTML
The main purpose of the rp tag is to enhance usability and accessibility by providing context for users on what they should expect for the ruby text when ruby annotations are employed. It acts as a bridge between standard browsers and those that support the ruby text rendering.
II. Browser Support
A. Overview of browser compatibility
| Browser | Support for rp Tag |
|---|---|
| Chrome | Supported |
| Firefox | Supported |
| Safari | Supported |
| Internet Explorer | Not Supported |
| Edge | Supported |
B. Importance of checking browser support
When developing web applications, it is critical to check for browser support of various HTML tags to ensure that web content is displayed correctly for all users. Relying on unsupported features could lead to a poor user experience, particularly for educational platforms or websites targeting diverse audiences.
III. Attributes

IV. Example
A. Sample code demonstrating the usage of the rp tag
Below is a complete example of how the rp tag can be implemented in an HTML document:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Using the rp Tag</title>
</head>
<body>
<h1>Understanding Ruby Annotations</h1>
<p>Here is an example of a ruby annotation for the kanji word for "Japan":</p>
<ruby>
<rb>日本</rb>
<rt>にほん</rt>
<rp>(にほん)</rp>
</ruby>
<p>For browsers that do not support the ruby feature, the standard reading is provided in parentheses.</p>
</body>
</html>
B. Explanation of the example code
This example demonstrates how to apply the rp tag in conjunction with ruby text:
- <ruby>: The parent container for ruby annotations.
- <rb>: Renders the main text, in this case, Japanese kanji for “Japan.”
- <rt>: Indicates the ruby text providing pronunciation.
- <rp>: Displays the fallback, here presented in parentheses when ruby is unsupported.
