🔠 Syntax of <dd> Tag

The <dd> element is used within a <dl> (description list) to provide structured definitions, explanations, or descriptions for terms specified using <dt>. Each <dt> can be followed by one or more <dd> tags, allowing expanded multi-definition entries that enhance readability and usability.

✅ Basic Structure of <dl> with <dd>

<dl>
  <dt>Term 1</dt>
  <dd>Definition for Term 1, providing clear context and meaning.</dd>

  <dt>Term 2</dt>
  <dd>First definition for Term 2, explaining the term concisely.</dd>
  <dd>Second definition for Term 2, offering an additional perspective.</dd>
</dl>

💡 Key Aspects

• ✔ Each <dt> (term) must be followed by at least one <dd> (definition), creating a structured and meaningful content hierarchy.
• ✔ Multiple <dd> entries can exist for a single <dt>, enabling broader explanations and multiple viewpoints where necessary.
• ✔ The closing </dd> tag is optional in HTML5, but including it ensures better document structure and compatibility with XML-based formats like XHTML.
• ✔ Description lists (<dl>) are more suited for definitions than unordered (<ul>) or ordered lists (<ol>), making them ideal for dictionaries, FAQs, technical glossaries, and metadata applications.
• ✔ Semantic clarity improves search engine optimization (SEO) and enhances accessibility for users relying on screen readers.

📌 Best Practice: Always explicitly close <dd> tags, particularly in XHTML-based documents, ensuring structured markup and clean formatting for reliable parsing.
