HTML

HTML is the foundational markup language of the web, providing structure and semantic meaning to every website and web application. It’s the essential technology that powers everything from simple blogs to complex applications at Google, Facebook, and Amazon.

What makes HTML powerful is its semantic elements and universal accessibility. Modern HTML includes multimedia support, form handling, web APIs, and accessibility features that make content usable by everyone, including those using assistive technologies.

Web developers and designers use HTML daily as the foundation for all web projects. Frontend developers structure their applications with it, while content creators rely on it for SEO-optimized, accessible web content.
