HTML is an abbreviation for HyperText Markup Language, a document format used to define web pages. HTML is characterized by content surrounded by elements (also called tags) which help describe the content. The HTML is typically rendered within a web browser for display to an end user.

[edit] Hello World
A minimalist Hello World example:
<html> <head> <title>Hello World!</title> </head> <body> <p>Hello World!</p> </body> </html>
Every HTML document must contain one top-level html element. Within that, there must be one head element and one body element. The head element must contain one title element. Any other elements within head and body are optional.

- head
- Defines meta data typically not displayed directly within web pages, but useful to web browsers and crawlers.
- title
- Always within head, defines the title of the page. It's used for display in web browser tabs and title bars. It's also used as a link title by most search engines.
[edit] Body
- body
- Defines the main content of the web page. The content within the body tag defines what's displayed within the main window of the web browser.
