HTML Description List

HTML Description List (DL) is a type of HTML markup used to create a list of terms and their corresponding definitions. It is also referred to as a definition list. The DL element is defined using HTML tags <dl> and </dl>. Each term and its corresponding definition are enclosed by the <dt> and </dt> tags and the <dd> and </dd> tags, respectively.

For example, the following HTML code creates a description list with three terms and their corresponding definitions:

<dl>
  <dt>Term 1</dt>
  <dd>Definition 1</dd>
  <dt>Term 2</dt>
  <dd>Definition 2</dd>  
  <dt>Term 3</dt>
  <dd>Definition 3</dd>
</dl>

When this code is rendered in a web browser, it will display as:

Term 1 : Definition 1

Term 2 : Definition 2

Term 3 : Definition 3

The appearance of the terms and definitions can be customized using CSS (Cascading Style Sheets) to match the design of the website.
