Now, once you have customized your fading colors,
you need to include your customized .js file on
every page that you want to use it in. You can
include javascript files using this syntax (in
the head of a document):

<script src="fade.js" language="Javascript"></script>

Now that you have the file included, you need to
setup your links a small bit.  Each link that you
want to fade needs to use the fade class.

Example:

<a href="blah.html" class="fade">click here</a>

Also, the link must be plain text.  This means
that you can't have <b>'s, <i>'s, <font>'s, etc.
inside of the link.

Example of what not to do:

<a href="blah.html" class="fade"><b>click</b> here</a>

Have fun!
