🙋 Introduction

The HTML <dl> (Definition List) tag plays a crucial role in structuring content that involves terms and their corresponding definitions.

In this guide, we will delve into the details of the <dl> tag and explore its various applications.

🤔 What is <dl> Tag?

The <dl> tag is used to define a description list. It typically consists of a series of terms (<dt> - Definition Term) and their corresponding definitions (<dd> - Definition Description). This structure is ideal for presenting glossaries, dictionaries, or any content where terms need clear and associated explanations.

💡 Syntax

The basic syntax for the <dl> tag involves enclosing a series of <dt> and <dd> pairs within the opening and closing <dl> tags.

  <dt>Term 1</dt>
  <dd>Definition 1</dd>
  
  <dt>Term 2</dt>
  <dd>Definition 2</dd>
  <!-- Add more term-definition pairs as needed -->
</dl>

🧰 Attributes

While the <dl>, <dt>, and <dd> tags don't have many attributes, you can still apply styling using classes or inline styles.
