I understand the parent's sentiment though. Every few years when I need to use Tex for something it always take me a second to remember that it is not a computer algebra system, just a rendering engine hyper focused on rendering 2D math notation that predates web rendering engines by about two decades. For some reason it surprises me that CSS did not grow to eat the publication rendering use case. I get that Tex has solved that problem quite well, but it seems like the sheer number of people who used CSS would mean that those capabilities would be ported to the language. But no, didn't happen. So we still have the two rendering languages.
