HTML

technology Maturity 7-9 Next article →

HTML is the standard language used to create documents for the web. It is a markup language that defines the structure of web content. This means it tells a computer how to organize information. When you use a web browser, it receives HTML files from a server. The browser then turns those files into the pages you see. These pages can include text, images, and even interactive forms.

HTML is very important because it acts as the foundation for everything online.

To build a page, you use things called HTML elements. These elements are the building blocks of the whole site. They work using special marks called tags, which use angle brackets. Some tags, like <img>, just introduce an object like a picture. Other tags wrap around text to provide extra information. The browser reads these tags to understand the page, but it does not show the tags themselves.

This way, the code stays hidden while the content appears clearly.

The story of HTML began with a physicist named Tim Berners-Lee. In 1980, he worked at CERN and created a system called ENQUIRE. Later, in 1989, he proposed a new system based on the Internet. By late 1990, he had specified HTML and written the first software. He worked with a data systems engineer named Robert Cailliau to find funding. The first public description of HTML appeared in late 1991. It was a simple design that used only 18 elements.

HTML has changed many times since those early days. In 1995, the first official standard called HTML 2.0 was published. Later, HTML 4.01 became a major version in 1999. The World Wide Web Consortium, or W3C, helps maintain these standards today. They work with other groups like the WHATWG to improve the language. A very important update arrived on 28 October 2014, when HTML5 was standardized. This newer version makes it easy to show video and audio.

Think of HTML as the skeleton of a building. It provides the shape and the rooms, but it does not provide the paint. To add color and style, designers use a tool called CSS. To make the page move or react, they use a language called JavaScript. HTML handles the structure, while CSS handles the look and layout. Together, these three tools work like a team. They turn simple code into the amazing websites we use every single day.
