Hyper Text Markup Language
What is HTML?
HTML is the lingua franca for publishing hypertext on the WorldWideWeb. It is a non-proprietary format based upon SGML, and can be created and processed by a wide range of tools, from simple plain text editors - you type it in from scratch- to sophisticated WYSIWYG authoring tools.
HTML uses tags such as <h1> and </h1> to structure text into headings, paragraphs, lists, hypertext links etc
