I'm going to convert HTML to PDF with quantumarticle.cls style file which I found here, but I do not know how to use it with the Pandoc. I have tried these:
pandoc --from html converted.html --to pdf --output output.pdf --metadata-file=metadata.yaml --pdf-engine=xelatex --standalone --mathml -V classoption=quantumarticle.cls
But I did not get the desired PDF. No errors. The PDF same without this option
