A Brief History of HTML
HTML, or HyperText Markup Language, is the standard language for creating web pages and web applications. Developed in the early 1990s by Tim Berners-Lee at CERN, HTML was designed to structure content on the World Wide Web, enabling the sharing of information across networks. The first version, HTML 1.0, was introduced in 1990 as a simple way to format text and link documents. Over time, HTML evolved through versions like HTML 2.0 (1995), HTML 4.01 (1999), and XHTML, culminating in HTML5, finalized in 2014 by the World Wide Web Consortium (W3C). HTML5 introduced semantic elements, multimedia support, and APIs, making it a cornerstone of modern web development.
What is HTML?
HTML is a markup language that defines the structure and content of web pages using a system of tags and attributes. It acts as the backbone of websites, allowing developers to organize text, images, videos, and interactive elements. HTML works in tandem with CSS (for styling) and JavaScript (for interactivity) to create dynamic, user-friendly web experiences. By enclosing content in tags, HTML provides a standardized way for browsers to interpret and render web pages.
How HTML Got Started
HTML emerged from the need to share scientific documents across the internet. Tim Berners-Lee, a physicist, proposed a system for hypertext documents that could be accessed via browsers, leading to the creation of the first web browser, "WorldWideWeb," in 1990. HTML was inspired by SGML (Standard Generalized Markup Language) but simplified for broader accessibility. As the internet grew, HTML evolved to support multimedia, forms, and complex layouts, driven by contributions from the W3C and browser vendors like Netscape and Microsoft.
