HTML vs. SGML: What's the Difference?
Edited by Aimie Carlson || By Janet White || Published on February 16, 2024
HTML is a markup language for creating web pages, derived from SGML, a standard for defining generalized markup languages for documents.
Key Differences
HTML (HyperText Markup Language) is specifically designed for creating and structuring content on the World Wide Web. SGML (Standard Generalized Markup Language), on the other hand, is a standard for defining markup languages used in various types of digital documents.
HTML is simpler and more rigid, tailored for web content with predefined tags. SGML is more complex and flexible, allowing the creation of custom markup languages for different needs.
HTML was developed from SGML, adopting its markup syntax but simplifying it for web use. SGML, predating HTML, was designed for a wide range of document types, not limited to the web.
HTML has a fixed set of tags, focusing on the presentation of content. SGML is more about structuring and organizing document content, with a focus on document architecture.
HTML is widely used and continually evolving, especially with the introduction of HTML5. SGML, while less prominent now, laid the groundwork for HTML and other markup languages.
