A quick word about how footnotes are implemented on this site…
In a recent post, The Case For a Demagogue, I used footnotes on this site for the first time, but I was not completely satisfied with the result. By using the HTML <sup> tag surrounding a hyperlink, it’s easy enough to format the footnote reference as a superscript and jump to it:
The problem is getting back to where you were in the text. A quick search revealed a good solution from John Gruber at Daring Fireball. He suggests 1) adding an ID for the footnote reference (I’ve used id="ref-footnote1" in the superscript), and 2) at the end of the footnote text, adding a link back to the footnote reference using its ID, along with a Unicode character often used to represent a carriage return. The way I’ve done it looks like this:
I like the way this works, so this will be the convention I follow going forward.
