Introduction to HTML

HTML (HyperText Markup Language) is the language every web page is built from. It doesn't do calculations or make decisions — it marks up content, telling the browser "this is a heading", "this is a paragraph", "this is a link".

When you visit a website, your browser downloads an HTML file and turns it into the page you see. Everything else builds on top of it: CSS styles the HTML, and JavaScript makes it interactive.
