Understanding Definition Lists in HTML

What is a Definition List?

A definition list in HTML is a specialized list format used to present terms alongside their corresponding descriptions. It is particularly useful for defining or explaining a set of terms.

Key Concepts

• HTML Tags: Definition lists utilize specific tags to structure content:
  • <dl>: This tag begins the definition list.
  • <dt>: This tag defines the term that is being explained.
  • <dd>: This tag provides the description or definition of the term.

Structure of a Definition List

A basic structure of a definition list is illustrated below:

<dl>
    <dt>Term 1</dt>
    <dd>Description of Term 1.</dd>
    <dt>Term 2</dt>
    <dd>Description of Term 2.</dd>
</dl>

Example

Here’s an example that demonstrates how to effectively use a definition list:

<dl>
    <dt>HTML</dt>
    <dd>HyperText Markup Language, the standard language for creating web pages.</dd>
    <dt>CSS</dt>
    <dd>Cascading Style Sheets, used for styling web pages.</dd>
    <dt>JavaScript</dt>
    <dd>A programming language used to create interactive effects within web browsers.</dd>
</dl>

When to Use Definition Lists
