One of the best looking HTML output from LaTeX can in fact be generated with https://www.softcover.io/ https://www.softcover.io/ . Although it uses a limited subset of LaTex called PolyTeX (see https://github.com/softcover/polytexnic https://github.com/softcover/polytexnic) I was able to convert my LaTeX documents quite easily to PolyTeX and generate good looking HTML output. Some example output can be seen in the manual http://manual.softcover.io/book/softcover_markdown#sec-embedded_math http://manual.softcover.io/book/softcover_markdown#sec-embed... The softcover tools (https://github.com/softcover/softcover https://github.com/softcover/softcover) are based on code developed for creating the HTML for http://tauday.com/tau-manifesto http://tauday.com/tau-manifesto and http://www.feynmanlectures.caltech.edu/ http://www.feynmanlectures.caltech.edu/. Internally Softcover uses https://www-sop.inria.fr/marelle/tralics/ https://www-sop.inria.fr/marelle/tralics/ to convert from LaTeX to XML/HTML. P.S.: I'm not affiliated with softcover.io in any way.
