HTML is almost always used in conjunction with two other front-end languages, CSS and JavaScript.
HTML: The Foundation of the Web

HTML (Hypertext Markup Language) is the core language behind every website on the internet. It defines the structure and content of a webpage, which your browser interprets and displays when you visit a site. Essentially, an HTML file stored on a server is what brings a web page to life in your browser.

However, HTML rarely works alone. It is usually paired with CSS (Cascading Style Sheets), which manages the look and layout—such as colours, typography, and page design—and JavaScript, which adds interactivity, animations and dynamic features. Together, these three front-end technologies create the modern web experience. The digital world has evolved dramatically from the static pages of Web 1.0, to the interactive and stylized Web 2.0 era, and now to today’s standard—responsive websites. A responsive website automatically adapts to different devices and screen sizes, ensuring smooth performance and accessibility without major adjustments.
