HTML: Hyper Text Markup Language
• Hypertext means "text with links in it." Any time you click on a word that brings you to a new webpage, you've clicked on hypertext!
• A markup language is a programming language used to make text do more than just sit on a page: it can turn text into images, links, tables, lists, and much more. HTML is the markup language we'll be learning
• An HTML document is a text file (script)• A web browser (Safari, Chrome, IE, Firefox, Opera, etc.)
interprets the script and presents appropriate contents
