Excessive indentation can [make reading difficult](#indented-elements) for narrow viewports, but preserving some indentation is still useful.
For now, I've decided to keep the indents on list elements (`<ol>`, `<dl>`, `<ul>`) since I often fill them with links (see this article's [table of contents](#toc) for an example). This indentation provides important non-interactive negative space. Readers with hand tremors [depend on this space](https://axesslab.com/hand-tremors/) to scroll without accidentally selecting an interactive element. Readers who double-tap to jump or zoom can't do so if there's no screen region that's "safe to tap".
