> Is anyone still working on WYSIWYG HTML editors?

Yep, I do time to time: https://html-notepad.com/ ( based on my Sciter Engine https://sciter.com )

It is almost impossible (mathematically speaking) to create reasonable WYSIWYG HTML and CSS editor.

So bad news for anyone looking for WYSIWYG editor to create meaningful web site from scratch using solely WYSIWYG.

For web site creation the only reasonable option is wizard approach - assembling site from predefined and prestyled blocks.

But, it is perfectly possible to create WYSIWYG HTML editor - editor that helps us to create and edit structured text - content portions of sites. That deals with pure HTML, styling is applied to that HTML at the point of content insertion.

The point of Amaya to me wasn't so much WYSIWYG HTML -- where "HTML" should probably be in scare quotes in most instances of such things. It was an actual SGML editor, respecting the DTD (like Emacs PSGML in that regard). I don't remember to what extent it was -- or could have been -- a general SGML editor with arbitrary DTDs. I also used it as a browser at one stage, but it was rather unstable then.

I remember that there was a general SGML editor called Thot (from INRIA) that it was built on. I was interested in generic SGML/XML editors at the time.

Aside from that, I think that Amaya was also used to provide a sample implementation of new/proposed web technologies. It's been a long time though and my memory is fuzzy.

Ah, yes; it was a long time ago -- and a somewhat simpler time. Plenty of good stuff comes from INRIA.

There are some tools but most of them tend to be of the "edit visually, export to HTML" variety which, TBH, makes a bit more sense since pure HTML doesn't have enough information for keeping track of repeated elements and the structure of an entire site. Even tools back in the day when WYSIWYG was way more popular that worked with HTML directly tended to use custom tags and attributes for additional metadata.

There are many products in the WYSIWYG HTML editing space. Webflow is valued at $2B and started out as a Show HN post around 2013, IIRC.

The biggest surprise to me is that Dreamweaver is still alive and kicking.

To be honest, they should call it Nightmarecleaver.

I've never used a better tool for imagemaps but then again that's the only one I've ever used.

Lots of visual editors on websites (e.g. wikipedia's editor) are really wysiwyg html editors for some specific subset of html (often using the browsers built in content-editable feature)
