A brief history of HTML
HTML was designed in 1992 by Tim Berners-Lee and Robert Caillau at CERN.
HTML is an instance of SGML, Standard Generalized Markup Language.
Originally, HTML specified strictly the logical structure, not the physical layout.
Pressure from users (mainly industry), forced subsequent version to allow
increasingly fine-grained control of the appearance:
- HTML is first defined
- HTML+ (some physical layout, fill-out forms, tables, math)
- HTML 2.0 (standard for core features)
HTML 3.0 (an extension of HTML+ submitted as a draft standard)
- Netscape-specific non-standard HTML appears
- Competing Netscape and Explorer versions of HTML
HTML 3.2 (standard based on current practices)
- HTML 4.0 (separates structure and presentation with style sheets)
- HTML 4.01 (slight modifications only)
- XHTML 1.0 (XML version of HTML 4.01)
