I found "Vapid" https://www.vapid.com/
Then it might be easiest to use this, and just totally "web interface it" using
You can even save your "working edit"folders to a cloud instead of pc
(like degoo's free 100gb cloud storage)
Then Finally use your perfered online "file minimizer for css/html/images etc"
(BUT KEEP YOUR WORKING COPIES FOR EDITS)
Example I made for you today to show it works:
edit: see here
Lektor - An easy to use static CMS and blog engine. - #Python <PURE HTML STILL NOT ON THE SITE HEADLESS CMS, TESTED BY ME, EASY/WORKS
^ THIS IS A "HYBRID" SSG/SSR, think less-techie user focused jekyll with "live in browser refresh" on file save (at this point its a "HOW NICE IS "WYSIWYG" YOUR TEXT EDITOR" issue)
Once all setup (very techie) this is it:
Here is the "WYSIWYG" part, super no tech easy:
Yellow - For people who make websites. - NO ITS: #PHP
TL;DR: You want to go here: https://getpublii.com/ , Its a "DESKTOP" SSG with Upload
Its the current popular "heavy" app, along with Open element (mid-weight) and Rocket-Cake (pretty light/portable). If desktop is forever "NO" run it from gitpod or w/e
Its not "an online csm" but even Bludit CSM (https://www.bludit.com/) & Pico CMS (http://picocms.org/)... the most minimalistic I can find (ps Bludit rocks) use PHP with JSON and both use a simple WYSIWYG interface to HTML via markdown
Jump over to https://neocities.org/tutorials
Neocities is DESIGNED on purpose as "exactly what your doing" a non-php based HTML/CSS BASED "static host"
They understand 99.9% of ppl are used to CSM's like Wordpress/Joomla. They suggest the "most used" generators.
I will directly reproduce the paragraph below:
Static Site Generators
Static site generators allow developers to make a web site that has many properties of dynamic web sites, except it generates static HTML which can then be uploaded to Neocities.
I also suggest you check the article: https://dev.to/matfrana/server-side-rendering-vs-static-site-generation-17nf
As the title says its about the world of SSR (server side rendering) vs SSG (static site generation).
SO, unless you get a way around needing a "SSH to PHP" process thats that.
