Linking to an id
Once you've marked an element using the
id
attribute, you can create a hypertext link to
that element using the
a
element
<a href=”#
id
”>
content
</a>
where
id
is the value of the
id
attribute of the element. For example, to create a link
to the
h2
heading for the letter A
in the glossary document, you would enter the follow-
ing code:
<a href=”#A”>A</a>
You'll change each entry on the Glossary page to a hypertext link pointing to the sec-
tion of the glossary corresponding to the selected letter.
To change the list of letters to hypertext links:
◗
1.
Locate the letter A in the list of letters at the top of the
glossary.htm
file.
◗
2.
After the
[
character, insert the following opening tag:
<a href=”#A”>
◗
3.
Between the letter A and the
]
character, insert the closing
</a>
tag. Figure 2-21
shows the revised code.

linking "A" to t
he
element with the id A
Make sure you include
the pound symbol (#) in
the hypertext link, and
ensure that the id text
matches both upper- and
lowercase letters in the
linked id.
◗
4.
Mark the letters B through F in the list as hypertext links pointing to the appropri-
ate
h2
headings in the document. Figure 2-22 shows the revised code for the list
of letters.

Gerry also wants you to create a hypertext link at the bottom of the file that points
to the top. You'll use the
id
attribute you created in the last set of steps.
