HTML - Hyper Text Markup Language
HTML is the language of the Web. (HTTP is the protocol of the Web.)
"HTML isn't a very good language for making Web pages. However, it has been a very good language for making the Web.
"HTML's ease of learning and the view source capability for browsers has bootstrapped the Web's popularity in an amazing way. The World Wide Web Consortium's (W3C) involvement in standardizing HTML has ensured that Web browsers all implement the same dialect, more or less. The emergence of CSS, and the corresponding growth of standards-based Web design as best practice has also averted HTML chaos and led to a better Web experience for users and developers alike."
