The <dt> tag is used in HTML to define a term in a definition list, generally within a <dl> (a definition list 😗).
It indicates a term that will be followed by its definition with the <dd> tag.
Â
Structure and syntax of the <dt> tag
Basic structure and syntax
Here is the basic syntax of a <dt> tag:
<dl>
<dt>Term</dt>
<dd>Definition of the term</dd>
</dl>The <dt> tag must always be used within the <dl> tag to specify a term, followed by the <dd> tag which gives the definition.
Â
Usage example
Here is an example of using the <dt> tag:
<dl>
<dt>HTML</dt>
<dd>Hypertext Markup Language, the markup language for structuring web pages.</dd>
<dt>CSS</dt>
<dd>Cascading Style Sheets, used for styling HTML documents.</dd>
</dl>In this example, we declare two definitions: first their title and then a brief description.
Â
Attributes
The <dt> tag does not accept specific attributes other than the generic ones like class, id, or style.
Â
Difference with other similar tags
<dl>: The<dl>tag is used to encapsulate a list of terms and their definitions, in which each term is defined by a<dt>tag and each definition by a<dd>tag.<dd>: The<dd>tag is used to provide the definition of the term specified in the<dt>tag.
