This post demonstrates the theme’s footnote treatment. The inline marker is a bracketed superscript number like Wikipedia or a research paper1, and each note carries a back-link ↩ that returns you to the spot you were reading.

Repeat citations are supported in Markdown: cite the same source twice and Hugo emits two separate fnref anchors, with one back-link per use on the note itself1. Clicking either back-link returns to the matching site.

Long-form notes work too2, including emphasis, links, and multi-sentence prose. The note body sits in the footnotes block at the bottom of the post, separated by a thin rule and labelled “Notes”.

Try this: click [1] above, then click the ↩ next to “Knuth (1974)”. Notice the brief background flash on the target — that’s pure CSS using :target and the theme’s --color-background-alt, so it works in both light and dark mode without JS.

  1. Knuth, D. E. (1974). “Structured Programming with go to Statements.” Computing Surveys, 6(4), 261-301. The original citation of “premature optimization is the root of all evil.” ↩︎ ↩︎

  2. This page also exercises the theme’s other typography bits — the prose measure stays at ~65ch, but the footnotes block follows the same narrow measure rather than expanding to the wider canvas reserved for code and figures. That makes notes feel like part of the reading column rather than a separate widget. ↩︎
