Sometime last year, I started doing these 24 exercises in TeX/LaTeX -- when I started, my idea was to show how TeX's very simple box-glue-penalty model (its "glue" is like springs with specified stretch and shrink) is yet general enough to do all the many things that Flexbox can do. I never got around to finishing it, and in the process I realized that much of what Flexbox focuses on are purely user-conveniences (e.g. allowing the user to specify "boxes" in a different order), and some of it (e.g. vertical typesetting) is actually nontrivial with TeX, though doable (and used by many in practice, wrapped into packages, which I was hoping not to use). So my project is abandoned for now and the existing document is in a very unpolished state, but in the meantime if anyone is interested, take a look -- (it has spoilers for the CSS exercises, and most of it only makes sense if you look at the (La)TeX source code, of which I'm definitely not an expert): https://www.overleaf.com/read/ssmrvhpwrmpn https://www.overleaf.com/read/ssmrvhpwrmpn
