Web Design in a Nutshell, 3rd Edition

Linking to a Fragment in Another Document

You can create a link to a named fragment of any document on the Web by using the complete pathname immediately followed by the fragment identifier. Of course, the fragment identifiers would have to be in place already. To link to the stocks section from another document in the same directory, use a relative pathname as follows:

<a href="dailynews.html#stocks">Go to today's Stock Quotes</a>

Use an absolute URL to link to a fragment on another site, as in:

<a href="http://www.website.com/document.html#fragment">...</a>
