Understanding Hypertext, Navigation, and Controls

Many people confuse the terms hypertext, navigation, and controls. This is understandable, since on the Web, hypertext and navigation links are both created with the same HTML code: <a>...</a>. But navigation is used to move from page to page within a Web site. Controls are used to let the visitor perform a specific action, such as submitting a form. Hypertext, on the other hand, may be any word, phrase, or image in a Web page that you click to get a more detailed explanation of that thing from anywhere on the Web. In theory, hypertext allows a single page to include a nearly infinite amount of information (Figures 1.13 and 1.14).

Figure 1.13. The Amnesty International site provides a good example of the difference between controls, navigation, and hypertext. The hypertext link in the main text offers access to a more detailed description of the term, and the navigation links move the visitor to another item on the site.
