History of HTML
HTML has changed a lot since the early days of the Web. Understanding its history helps you see why modern HTML looks the way it does today.
HTML was created to make it possible to structure and connect information on the Web. Over time, new versions and standards added better structure, multimedia, forms, accessibility, and semantic elements.
You do not need to memorize every historical specification. The important idea is to understand how HTML evolved from a simple document-markup system into the modern HTML standard used by browsers today.
đ The HTML timeline
The Web is proposed
Tim Berners-Lee proposed the World Wide Web while working at CERN. The idea was to make information easier to share and connect through hypertext.
HTML is introduced
Tim Berners-Lee introduced HTML as a way to structure documents containing headings, paragraphs, links, and other information.
HTML+
Dave Raggett drafted HTML+, an early proposal for extending HTML with additional capabilities.
HTML 2.0
HTML 2.0 became an important standardized version of HTML and helped establish a common foundation for Web documents.
HTML 3.2
HTML 3.2 added and standardized more capabilities used by Web pages of the time.
HTML 4.01
HTML 4.01 became a widely used standard and provided a strong foundation for structured documents and forms.
XHTML 1.0
XHTML 1.0 reformulated HTML 4.01 using XML syntax rules, encouraging stricter and well-formed markup.
HTML5 development
Work on HTML5 became a major step toward a modern Web platform, with richer semantics, multimedia, graphics, and application features.
HTML5 Living Standard
WHATWG moved HTML toward a living-standard model, where the specification continuously evolves instead of depending only on occasional numbered releases.
Modern HTML
HTML5 became widely established, while the Web platform continued evolving through the living HTML standard used by modern browsers.

đ How HTML evolved
Early HTML pages were mostly documents with headings, paragraphs and links. Modern HTML can describe page structure semantically and work with multimedia, forms, graphics, storage, geolocation and other browser capabilities.
This evolution is why modern HTML development is not just about making text appear on a page. Good HTML also communicates meaning and structure to browsers, search engines, assistive technologies and other tools.

No. Learn the important milestones and focus on writing modern, semantic HTML.
Browser compatibility does not mean old practices are recommended. Prefer modern semantic HTML.

đ¯ Interview questions
Who invented HTML?
HTML was introduced by Tim Berners-Lee as part of the early World Wide Web.
What is HTML5?
HTML5 refers to the major generation of HTML that introduced many modern Web capabilities and semantics.
Is HTML5 the latest numbered version of HTML?
Modern HTML is developed as a living standard, so it continuously evolves rather than relying only on numbered versions.
What is XHTML?
XHTML 1.0 was a reformulation of HTML 4.01 using XML syntax rules.
