I started to develop a minimal version of FosseryWeb 1-2 weeks ago, with the aim of Dillo and NetSurf compatibility, I just "finished" the site (in the sense that all articles and cheatsheets are available there).
In the beginning, it was a bit challenging to find ways to implement the planned design in a way that it isn't broken in the above mentioned browsers, but actually it was a fun challenge, it was a bit like a "don't use modern CSS features" challenge lol. I had to make some changes to the originally planned design to make it work, but hope you like it.
Besides the compatibility thing, I also made the site as lightweight as possible, by including only the necessary CSS styles for each page (mostly), and only include images where it's necessary (e.g. in a few cheatsheets).

If you noticed a bug or have any recommendation, feel free to drop a comment.
I'm aware of some article/cheatsheet download issues mentioned on the Known issues section of the About page (https://fosseryweb-min.codeberg.page/about.html), but I couldn't find a solution for those yet (some of those are browser-related, so I can't really do anything about them I guess). I could solve the Dillo issue by including Markdown files in zip, but even then, unzipping it is one extra step, so it wouldn't be any better than right clicking on the link imo.
