Web technologies

The foundational stack—HTML, CSS, and JavaScript—plus critical protocols (e.g., HTTP/3) and APIs that structure, style, and power all content delivered across the internet.

Web technologies are the essential programming and protocol suite that constructs the modern internet. The core triad is HyperText Markup Language (HTML) for document structure, Cascading Style Sheets (CSS) for visual presentation, and JavaScript for client-side interactivity (e.g., dynamic updates). This system is supported by application protocols like HTTP/3 for efficient data transfer and various Web APIs (Geolocation, WebGL) enabling advanced functionality. These technologies form the foundation for everything from simple static pages to complex, dynamic applications built with frameworks like React or Vue, ensuring an open, interoperable, and accessible user experience across all major browsers.
