fyi, added entry to my tex4ht cheat sheet which shows few math fonts and how they show in HTML and the status of each. Currently there is 9 fonts given, most of them using code from posts at Tex.Stackexchage.
http://12000.org/my_notes/faq/LATEX/math_fonts/index.htm I'll be adding more. For each font, there is a pdf file and HTML, and the source code used. All were compiled using make4ht using svg mode. I like this one most so far \usepackage[libertine]{newtxmath} These are the ones compiled now: 1 mathpazo,eulervm 2 mathpazo,mathabx 3 kpfonts 4 newtxtext,newtxmath 5 libertine,newtxmath 6 stix 7 lmodern 8 mathpazo 9 txfonts ------------------ If you know of some other combination I could add to the list and build the example with it, please send it to me and will add it. I am always looking for the best math and text font to use with tex4ht :) --Nasser
