MathJax VS markdown-it-katex

As others have pointed out Obsidian is using MathJaX, which is a custom implementation of a subset of TeX. It doesn't support Tikz, which is way different from the equation subset of TeX, but there is a discussion here: https://github.com/mathjax/MathJax/issues/41

Nice. Almost what I want: simplicity, images (for plots), and no adds or tracking. However, I want to author pages on optics, and I want to use MathJax (https://www.mathjax.org/) for equations. Please let me know how I might use MathJax with Mataroa if I've misunderstood. Or, please suggest something similar that supports MathJax. Rolling my own static site (as many NH postings describe) is enticing but beyond my ability. I am not a Web programmer, and Mataroa's simplicity is perfect for me.

I am using https://www.mathjax.org/ for learning math. Is there any library for CLJS that can do math notation/writing like this library does?

Obsidian uses a subset of LaTeX, and it's meant only to typeset some relatively basic maths. It does this using MathJax. Here's the list of supported commands and environments.

I think my current pet peeve is LaTeX's fixed output. I've been a (La)TeX user for 30+ years, starting off with plain TeX and Knuth's "The TeXbook", followed by Lamport's book on LaTeX. But I wonder whether its day is past. So much of my writing now is read online that I look for publishing solutions that have flexible outputs: the LaTeX -> PDF road, although my go-to for years, simply doesn't cut it any more. People read my stuff online, on computers, tablets, mobile phones of all sorts of sizes and orientations, that a fixed page like PDF has become more of a liability. So I'm moving away from "pure" LaTeX to org-mode with export to HTML, and using MathJax for the equations, and something like JSXGraph for (interactive) diagrams.

Thanks a lot! I see now, I am able to reproduce the issue if I go into chrome://flags, search for "Auto Dark Mode for Web Contents", and select "Enabled with simple HSL-based inversion". Just choosing "Enabled" seemed to break the LaTeX entirely. (Please let me know if that isn't roughly what you did)

I don't know how I'll fix this (I've never really debugged mobile web specific stuff before), but I'll look into it this weekend.

There must be a way to fix it, since I don't see the issue when going to https://www.mathjax.org/#demo and entering something like this: $$\frac{1}{\sqrt{2}}$$

LaTeX equation display uses MathJax in a webview.

Also, if you support markdown at some time, could you also support LaTeX / KaTeX or some similar TeX functionality for math notations? Some GitHub repos like this one have implemented TeX functionality within markdown. This can be a useful functionality for students and researchers who need math support within notes.

So I guess recently, VS Code now natively supports Markdown preview natively, which is amazing. I guess they're "targeting" CommonMark__ via the markdown-it compiler. Though absent from the docs, the VS code markdown preview seems to accomodate math-mode enviroments which is awesome, I presume defined by a markdown-it extension such as markdown-it-katex though I can't seem to find actually documentation on the math-mode implementation in VS Code. Strange...
