Traditionally footnotes are used to cite academic or literary references, or to add in additional information, such as pronunciations or explanations of foreign terms. They can also used to great effect as witty asides.
Syntax and Usage
<FOOTNOTE> block is translated into a superscripted numeral, with the text of the footnote placed at the end of the entry. The numerals are hyperlinked from the text to the bottom of the page and back again, so you can click on a footnote to read it, and click once to return to the main text again.
In Internet Explorer (Windows version only), Netscape 6.1 onwards, and Opera, footnotes will also show as hover text if you place your pointer over the footnote numerals.
Nested footnotes number correctly, but hover text in Internet Explorer does not display correctly; it shows the nested footnote's text as well.
For a footnote1 simply do this.
For a nested footnote2 simply do this.
