Chapter 1: The Least You Need to Know about HTML, CSS, and the Web
Steer clear of word processors like WordPad or Microsoft Word when creat-
ing HTML. They introduce all kinds of extra code to Web pages that you may
neither want nor need.
The World Wide Web comes by its name honestly. It’s quite literally a web of
online pages hosted on Web servers around the world, connected in trillions
of ways by hyperlinks that tie pages together. Without such links, the Web
would be just a bunch of standalone pages.
Much of the Web’s value comes from its ability to link to pages and other
resources (such as images, downloadable files, and media presentations) on
either the same Web site or at another site. For example, USA.gov (www.usa.
gov) is a gateway Web site — its sole function is to provide access to other
Web sites. If you aren’t sure which government agency handles first-time
loans for homebuyers, or you want to arrange a tour of the Capitol, visit the
site shown in Figure 1-1 to find out.
Figure 1-1: USA.gov uses hyperlinks to help visitors find government information.
Web browsers were created specifically for the purpose of reading HTML
instructions (known as markup) and displaying the resulting Web page.
