Real-World Examples
Weblogs
- "Blank Slate" on Daring Fireball uses an ordered list for endnotes, and uses the ID attribute in a list item to link to a specific endnote. Also in the ID attribute is the date of publication, to differentiate footnotes if more than one publication (in this case blog posts) occur on a page.
<div class="footnotes">
<hr />
<ol>
...
<li id="fn2-2007-03-04">
<p>It took me six weeks to choose the exact shade of Daring Fireball’s
background color, <code>#4a525a</code>.
<a href="#fnr2-2007-03-04" class="footnoteBackLink" title="Jump back to footnote 2 in the text.">↩</a>
</p>
</li>
...
</ol>
</div>
Essays/Tutorials
- Dan Cohen's "The Future of Preserving the Past" uses the following markup for the initial reference in the main text, and the content for the footnote:
<sup><a href="#_edn4" name="_ednref4" class="enref" id="_ednref4">4</a></sup>
<p> <sup><a href="#_ednref4" name="_edn4" class="enref" id="_edn4">4</a></sup>National Institute of Standards and Technology, “Documentary Information Received by NIST,” <a href="http://wtc.nist.gov/media/docs_info_received.htm"> http://wtc.nist.gov/media/docs_info_received.htm </a>, accessed May 11, 2005. </p>
- In "Scholarship on the Web: Managing Endnotes, Paula Petrik's basic CSS example uses the following markup for the footnote content:
<div id="footnotes"> ... <p><a href="#fn2ref" class="note">2</a><a name="fn2text" id="fn2text"></a> E. Landells, <em>The Boys’ Own Toymaker: A Practical Illustrated Guide to the Useful Employment of Leisure Hours</em> (London: Griffith and Farran, 1860), vii.</p> ... </div>
- Scholarship on the Web Superscripted Example add the <sup> element to superscript the note numbers.
<div id="footnotes"> ... <p><sup><a href="#fn3ref" class="note">3</a></sup><a name="fn3text" id="fn3text"></a> Paula Petrik, “The Paraphernalia of Childhood: Advice on Toys” from “Playthings for the Republic’s Children: American Culture, Toys, and the Business of Play,” unpublished manuscript.</p> ... </div>
- Formatting Footnotes with JavaScript and CSS is a technique by Timothy Groves that displays footnotes inline with text, then hides/displays the note content with JavasCript. Groves uses the following markup structure:
- This technique is problematic from a microformats perspective for several reasons: numbers are not used, each note does not have a unique ID, and its difficult or impossible to tell the difference between an annotation and the rest of the text without JavaScript and/or CSS.--JeremyBoggs 08:46, 14 Mar 2007 (PDT)
<p>Lorem ipsum dolor sit amet...<span class="footnote">This is a footnote.</span>...</p>

Existing Practices
Common Patterns Discovered
- Use of "footnotes" as a class or ID attribute value for differentiating footnote content from the body of the publication.
