As we've mentioned, hypertext is text that contains links to other
text. How do we create such a link? The answer comes in the form of
the anchor tags <a>...</a>. The
anchor is the "clickable" bit that takes you to the link. The
"Next Page" link at the bottom of this page could be generated with
the HTML:
<a href="colours.html">Next page</a>
The link is comprised of anything in between the
<a> and </a>, and by default
most browsers will underline it to indicate that it is a link. The
attribute href means that this anchor defines a
hypertext reference. Since we only specified a filename the
browser will look for it in the current directory, but we can specify
any URL, e.g.:
<a href="http://www.w3.org/People/Raggett/book4/ch02.html">A history of HTML</a>
which produces:
A history of HTML
Notice that we've explicitly stated that the browser should use the
hypertext transfer protocol (HTTP) for this transaction. You might
think this would be the default, but that is not true; if we omitted
this then the browser would look for a file in the current directory
called "www.w3.org/People/Raggett/book4/ch02.html" - not exactly what
we wanted! If you ever need to explicitly tell a browser to look for a
local file, you can state "file://" instead of "http://".
Find the phrase "University of York" in your introductory paragraph, and make that a hyperlink to the University of York's home page (http://www.york.ac.uk).
