<dd> : Description Details element

by

Introduction

The ‘<dd>‘ element in HTML is used as part of a definition list ‘<dl>‘, representing the description or definition of a term in the list. It is typically used in conjunction with the ‘<dt>‘ definition term element. The combination of ‘<dt>‘ and ‘<dd>‘provides a way to structure and present term/definition pairs on a webpage.

Here’s an example of how ‘<dt>‘ and ‘<dd>‘ are used together :

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Document</title>  
</head>
<body>
    <dl>
        <dt>HTML</dt>
        <dd>HyperText Markup Language is the standard markup language for creating web pages.</dd>
        <dt>CSS</dt>
        <dd>Cascading Style Sheets is a style sheet language used for describing the look and formatting of a document written in HTML.</dd>
        <!-- Additional term/definition pairs can be added as needed -->
    </dl>    
</body>
</html>

Output :

In this example, ‘<dt>‘ is used to define terms (e.g., HTML, CSS), and ‘<dd>‘ is used to provide the corresponding descriptions or definitions. When rendered by a browser, this creates a structured list where each term is followed by its associated description.

Uses of <dd> tag :

Here is some uses of <dd> tag :

    </dl>      
</body>
</html>

5. Coding Documentation: When documenting code or APIs, you can use <dt> to represent method or function names and <dd> to provide detailed explanations or usage instructions.

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Document</title>

        <dt>API Endpoint /users</dt>
        <dd>Returns information about users in the system...</dd>
        <!-- Additional code documentation pairs -->
      </dl>
