Hypertext is text displayed on a computer display or other electronic devices with references (hyperlinks) to other text which the reader can immediately access, or where text can be revealed progressively at multiple levels of detail (also called StretchText). The hyper<wbr>text pages are interconnected by hyperlinks, typically activated by a mouse click, keypress sequence or by touching the screen. Apart from text, hyper<wbr>text is sometimes used to describe tables, images and other presentational content forms with hyperlinks. Hyper<wbr>text is the underlying concept defining the structure of the World Wide Web, with pages often written in the Hypertext Markup Language (HTML). It enables an easy-to-use and flexible connection and sharing of information over the Internet.
