suggestion: support latex math expressions using remark-math and rehype-katex

[gyunseo]

I think support latex math expression in markdown is a good option like the following image.

Thank you

Appreciate your suggestion and effort.
However, I'm thinking of adding a how-to blog post for adding support latex math expressions. This is because AstroPaper is aimed to be as minimal as possible; and, besides, not everyone using AstroPaper would need this feature. But if someone does, they can opt in this feature by following the how-to blog post guide.

I tried adding katex using the same process you described, and it worked quite well, except that the colors are messed up in dark mode:

As you can see, the math text is very very faint. Does anyone have any idea how to fix this?

I followed this tutorial and didn't have this issue @andreyyao https://blog.alexafazio.dev/blog/render-latex-in-astro/

@caleb-shelton I just did a fresh install, and it's the same issue. Which version of remark-math and rehype-katex are you using?

EDIT: Upon further inspection, I think tailwindcss or the dark mode toggle is not playing right with the katex expressions. I got a temporary fix working by overwriting this css in layouts/PostDetails.astro:

 /* This is fixing the dim color of katex in dark mode */
 .prose {
     color: var(--color-text-base);
 }

@andreyyao I didn't know that issue since I always use light mode. I've found the same issue with yours on my blog. I fixed it using your modification on layouts/PostDetails.astro. thanks so much! :D
