There are millions of web pages around the world and they are all exactly the same in
one way: they are all pages of text with coded messages telling a browser what to do.
Every web page can be opened in a word processing program; in fact many people create web
pages with a word processing application. The code used to create the instructions for the
browser is called HTML. You don't need to know it to create web pages and with web
authoring software you don't even have to think about it.
