Chapter 5. Web Linking
A link provides a means of navigation from one resource to another. There are many everyday examples of links. Travelers use street signs and maps to decide which way to travel. Books and articles use footnotes and references to direct readers to related material. In software, we use variables and pointers to create links between different parts of an application.

</head>
<body>

use the first link element to discover the stylesheet
associated with this HTML document. A feed reader can use the second
link to fetch a related Atom feed. The img element points to another related resource, an image file, that the browser can render on the screen. ...
