I have always wanted to use more footnotes[1]. And I have always coveted folks who have managed to pull off having their footnotes hang out in the sidebar. Just feels like a better reading experience for an aside, which is how I mostly use them. Michelle Barker demos how the coming-soon CSS Anchor Positioning will make it easier to accomplish. Unfortunately I’m not sure where Webkit/Safari is with implementing. But checking out the demo in latest Chrome, I hope it’s soon.
I use a combination of a VSCode extension and a markdown-it plugin with Eleventy. ↩︎
