What it is and the problem it solves
HTML is a markup language that web browsers use to interpret and compose text, images, and other material into visible or audible web pages. It solves the problem of inconsistent, non-interoperable hypertext formatting on early networks.
How it works
HTML uses angle-bracketed tags to define structural semantics — headings, paragraphs, lists, links, quotes — for plain text. It is an application of SGML, with syntax formally defined by an SGML DTD in the IETF’s 1993 Internet Draft.
What works
HTML elements serve as the building blocks of HTML pages. They denote structural semantics reliably. Browsers parse them consistently. The SGML foundation ensures syntactic rigour and extensibility.
What does not
HTML does not render presentation. It does not execute logic. It does not manage state. It does not define behaviour. It does not enforce validation beyond SGML parsing rules.
What it changes
It replaces proprietary document formats with a shared, tag-based grammar for hypertext composition — enabling interoperable, browser-driven rendering across networks.
Is it worth your time
Yes — if you need to structure document content for browser interpretation. No — if you require styling, interactivity, or data handling. It does one thing well and nothing else.
