🧠 How HTML works

HTML (HyperText Markup Language) is the markup standard for web pages. A document begins with a DOCTYPE and consists of elements (tags) placed inside head and body. Modern HTML5 includes semantic tags (article, section, nav), forms, multimedia and is supported by all browsers. The specification is the WHATWG HTML Living Standard.
