Setting a max-width on regular textual content is good for readability, which in turn increases accessibility. See this W3C a11y documentation (1) and an a11y page by the US government (2) for more detailed info.

Using the CSS max-width property makes narrower sizes possible (for smaller screens) but sets an upper limit. The newer `ch` unit in CSS is a good-enough approximation of the average width of a character. I've seen 66ch as the "ideal" width for regular text. For the docs code examples need to have enough width too of course. But we can have those be wider than their containing element if need be.

This prevents people from having to scroll to the top, find out which table-of-content-link they have to click to get the deeplink of where they wanted to link. This is actually quite a common pattern. See the Python docs (2) and the Mozilla docs (3) as examples. The pattern on those sites is even a little nicer by showing an icon on hover.

Cool! I could help if you want to.
