I found it hard to understand the point of this. It talks about imitating the “look and feel” of LaTeX documents in HTML, but fails to do so. If the article itself is an example, it’s the familiar low-quality browser-rendered HTML typography.
This is maybe the third time I've seen the concept of a LaTeX styled html page and it never seems like a good idea to me. I'm all for math typesetting in HTML, but I no longer "believe" in justification, especially not browser's dissatisfying one-paragraph based techniques. But even with knuth-plass I have reasons to suspect ragged right text is better, see <a href="https://news.ycombinator.com/item?id=27189306" rel="nofollow">https://news.ycombinator.com/item?id=27189306</a>
I'm willing to change my mind with more evidence, justified text <i>is</i> pretty.
I've found that Texmacs produces some nice and fast html pages, like this: <a href="https://www.texmacs.org/joris/pcomp/pcomp.html" rel="nofollow">https://www.texmacs.org/joris/pcomp/pcomp.html</a><p>However, I don't know if there's a way to use it for regular Tex documents.
Producing Computer-Modern-y HTML output that looks like a defaults-everywhere LaTeX document reminds me of George Bernard Shaw's reputed response to a marriage proposal from a noted actress: “But what if the baby had MY looks and YOUR brains?”
