💡 Key Idea
HTML is the Skeleton of Every Web Page
Structure before style.
HTML (HyperText Markup Language) is not a programming language — it's a *markup language* that uses tags to define the structure and content of a web page. Every website you visit relies on HTML to arrange text, images, links, and media into a readable document.
