Dear Michal, Thanks for the code. I'll try to construct a MWE for the MathML issues but that may take a while.

It seems that I was wrong, mjcli uses MathML by default. When you use the "mathjax" option, it uses the LaTeX math syntax for the command line MathJax, but it doesn't remove the MathJax <script> element from the HTML file. You can remove the MathJax <script> using following .mk4 build file: -------------------------------------- local domfilter = require "make4ht-domfilter" local process = domfilter { function(dom) for _, el in ipairs(dom:query_selector("#MathJax-script")) do el:remove_node() end return dom end } Make:match("html$", process) ------------------------------------ Then there is the issue with MathML. It seems that there is an issue with the LaTeX to MathML conversion in your case, so several things fail. First, make4ht process MathML and fixes some common issues. It fails, as it reports the issue "Unbalanced Tag (/mstyle)". I suppose that the mjcli error is caused by the invalid MathML too. Could you try to make a MWE that runs into this issue? As I said, there can be some issues that need to be fixed in the LaTeX source in the worst cases. Best regards, Michal >I didn't explicitly use the "mathml" option.
