What is HTML?

HTML (HyperText Markup Language) is the standard markup language used to create and structure web pages. It tells the browser how content like headings, paragraphs, images, videos, tables, and links should appear on a webpage.

HTML is not a programming language — it is a markup language. It uses tags and elements to define the structure of a webpage. Every website on the internet uses HTML as its foundation.

HTML works together with CSS and JavaScript. HTML creates the structure, CSS adds styling and design, and JavaScript adds interactivity and dynamic behaviour.
