HTML
From Official XMG Wiki
HTML is the strange language that web browsers understand. It's not a programming language. It's a markup language. Essentially, all you are doing is "marking up" the text so the browser knows how to display it. After all, browsers are essentially stupid beasts.
It's a bit like being an editor with his editor's pen. Want that word to be bold? Well then mark it up. Want your header bright pink? Well then mark it up. It's really that simple.
Some may think that HTML is old, boring, and not quite that jazzy Web 2.0 that we've all been hearing about. However, not only can HTML be used to place a "BETA" image on a webpage, it also forms the foundations of webdesign. No matter how complicated your backend, no matter how clever your JavaScript, you are eventually going to have to render it all down into HTML so that your visitor's browsers can understand it.
