MathJax-src VS markdown-it-texmath

I am using MathJax from Emacs org-mode and it is grabbing MJ 3 from https://cdn.jsdelivr.net/npm/mathjax@3/es5/tex-mml-chtml.js In Emacs I supposedly have configuration options to get, for example, the LaTeX Euler font -- or a few others. But it doesn't seem to work. I inspect my web page output and I see a CSS class MJX-TEX, and it's CSS breakdown is .MJX-TEX { font-family: MJXZERO, MJXTEX; } Good. I think I can simply go into my own CSS and change something with the font family. But I wouldn't know what to. I found this code where it seems to have a long list of "font families" but I have no idea what they are or how to change the above CSS font-family tag. I read that 3 doesn't allow changing fonts. Is that still true? Any knowledge on how to handle/change fonts appreciated.

One thing that the article gets wrong is accusing mathjax of being abandoned. Development has moved to a new repo for the next version.

Obsidian uses MathJax for their LaTeX integration, so it will auto center without using any of the formatting syntax. You only need to put in your equations and it will format automatically.

Github's implementation is really lazy. There are many much better approaches to precisely this problem. E.g., Jupyter notebooks implement one that has matured in the wild over a decade. There's this very flexible markdown-it plugin that implements anther https://github.com/goessner/markdown-it-texmath, and my version of it here https://github.com/sagemathinc/cocalc/blob/master/src/packag... which I rewrote in typescript with a focus on the same semantics as Jupyter has, but for CoCalc, and I've been working on using unifiedjs to provide more general latex for Markdown (not just formulas) here https://github.com/sagemathinc/cocalc/pull/5982 Parsing math is much easier if you use a plugin to an existing markdown parser, rather than trying to do some hack outside of that (which is what Github probably does, and also what Jupyter does).

If you use a proper markdown plugin to parse math instead (such as https://github.com/goessner/markdown-it-texmath), then the problems pointed out in this blog post go away.
