As the building blocks of the World Wide Web, HTML (Hypertext Markup Language) is one of the most fundamental and important languages for any web developer to master. At its core, HTML provides the structural framework for creating websites by allowing you to define headings, paragraphs, lists, links, images, and other content elements.
While HTML on its own doesn’t control the styling or interactivity of a webpage, it lays the crucial groundwork that cascading style sheets (CSS) and JavaScript build upon.

Whether you’re brand new to web development or brushing up on your skills, understanding HTML is the first step to creating well-structured, accessible websites.
HTML Versions

Here is an overview of the major HTML versions:
HTML 1.0 (1991)
- The first version of HTML was introduced by Sir Tim Berners-Lee, the inventor of the World Wide Web. HTML was just a simple markup language with a small set of tags.
- Focused on basic text formatting like headings, paragraphs, and lists.
HTML 2.0 (1995)
- Added more structural elements like form controls, tables, and image maps.
- Allowed better formatting and layout capabilities.
HTML 3.2 (1997)
- Introduced minimal support for tables, text flow around images, and super/subscript.
- The first version is to try and formalize HTML as a standard.
HTML 4.01 (1999)
- A major revision that became an official standard.
- Added ability to style elements, embed objects, and improve accessibility.
- Introduced the basics of HTML forms and frames.
XHTML (2000)
- An XML-based reformulation of HTML 4.01.
- Stricter syntax rules to conform to XML standards.
- Never gained widespread adoption due to its stricter error handling.
HTML5 (2014)
- A major overhaul and extension of HTML.
- Added semantic elements like <header>, <nav>, <article>, <aside>.
- Incorporated audio, video, and canvas for media/graphics.
- Improved forms, web storage, and offline capabilities.
- Emphasis on creating one language for all platforms/devices.
These continue evolving to add more accessibility features, improve media handling, and keep up with modern web demands.
With each new version, HTML aimed to provide better structure, more semantic meaning, rich multimedia support, and alignment with changing technology needs. HTML5 was particularly transformative in extending HTML for mobile and cutting-edge applications.

Hello World using HTML
Here’s a basic “Hello World” program in HTML:
<!DOCTYPE html>
<html>
<head>
<title>Hello, World!</title>
</head>
<body>
<h1>Hello, World!</h1>
<p>This is a basic HTML document.</p>
</body>
</html>
This HTML document consists of the following components:
- <!DOCTYPE html>: Declares the HTML5 document type.
- <html>: The root element that wraps the entire HTML content.
- <head>: Contains meta-information about the HTML document, such as the title.
- <title>: Sets the title of the HTML document (displayed in the browser tab).
- <body>: Contains the visible content of the HTML document.
- <h1>: Represents a top-level heading.
- <p>: Represents a paragraph of text.
In this example, the document title is set to “Hello, World!”, and the body contains a top-level heading (<h1>) with the text “Hello, World!” and a paragraph (<p>) with additional text. When you open this HTML document in a web browser, you’ll see a webpage with the “Hello, World!” heading and the accompanying paragraph.
