HTML <dd> Tag

The HTML <dd> tag is used within a description list (<dl>) to define the description or value of a term specified in the corresponding <dt> (description term) tag. The <dd> tag stands for "description data" and is used to provide additional information or details about the term. In web development, the <dd> tag is often used in combination with the <dl> (description list) and <dt> tags to create structured lists that pair terms with their descriptions.
