Document Type Definition - What is a document type definition in CSS?
Answer
A Document Type Definition (DTD) in Cascading Style Sheets (CSS) outlines the document's contents and its tree structure. This set of markup declarations defines a document type for the SGML family, which includes GML, SGML, HTML, and XML. An XML document can define a DTD inline or as an external suggestion.
