It tells the browser what each piece of content is: a heading, a paragraph, a link, an image, a navigation menu, and so on. - **HyperText** means text that links to other text, so users can move between documents non-linearly. - **Markup** means content annotated with tags. - **Language** means it has a standardized syntax defined by a specification. The three core web technologies work together: | Technology | Role | Analogy | | --- | --- | --- | | HTML | Structure and meaning | Skeleton | | CSS | Presentation and layout | Skin and clothing | | JavaScript | Behavior and logic | Muscles and brain | **Why it matters:** Even React, Vue, Angular and Next.js end up producing HTML in the browser's DOM. Browsers, search engines, and screen readers all consume that HTML. Poor HTML means poor accessibility and poor SEO, no matter which framework you use. ### Is HTML a programming language? \[Essential\] No. HTML is a **declarative markup language**. It describes what content is; it does not compute anything. It has no variables, loops, conditions, or functions. **Common trap:** "But HTML5 has APIs like Canvas and Geolocation." Those APIs are used through JavaScript. The markup itself remains declarative. ### What is the difference between HTML and HTML5? \[Essential\] HTML5 is not a separate language. It is the major evolution of HTML (published as a W3C Recommendation in 2014). Today the language is maintained as a continuously updated **HTML Living Standard** by WHATWG, so you will often hear "modern HTML" instead of "HTML5". HTML5 added: - Semantic elements: `
