HTML Description Lists
An HTML Description List is not as commonly used as unordered or ordered lists but serves an important purpose for displaying name-value pairs. This type of list is marked up using three tags: <dl>, <dt>, and <dd>.
- <dl> (Description List): This tag defines the description list itself and acts as a container for the list items.
- <dt> (Description Term): Represents a term or a name within the list.
- <dd> (Description Details): Provides the description or definition of the term.
Syntax:
<dl>
<dt>Coffee</dt>
<dd>A hot drink made from roasted coffee beans.</dd>
<dt>Espresso</dt>
<dd>Strong coffee brewed with steam through ground beans.</dd>

Nested Description List
A nested description list is when we add a description list inside another description list. This allows for organizing related terms and their definitions in a hierarchical structure, as demonstrated in the example:
Example 2:
<!DOCTYPE html>
<html>
<head>
<title>Nested Description List</title>
</head>
<body>

- FAQs
- Glossaries
- Product descriptions
- Technical specifications
- Any content where terms need definitions
