Use the <dl> tag in HTML to add the glossary definitions. The HTML <dl> tag is used for declaring a definition list. This tag is used within <dd> tag.
A definition list is similar to other lists but in a definition list, each list item contains two entries; a term and a description.
Example
You can try to run the following code to implement <dl> tag −
<!DOCTYPE html> <html> <head> <title>HTML dl Tag</title> </head> <body> <dl> <dt>Definition List</dt> <dd>A list of terms and their definitions/descriptions.</dd> <dt>HTML</dt> <dd>An HTML tutorial.</dd> <dt>PHP</dt> <dd>An PHP tutorial.</dd> </dl> </body> </html>
