I would gladly pay this price as a monthly subscription, if only I could get a maintained CSS library that lets me build applications on a level similar to Semantic UI, with the ability to customize or theme components.

I don't want JavaScript, I don't want a "framework", I don't want an npm-installable-monster, I want something that produces CSS that I can use for business. Semantic UI was close, but it got abandoned, and the forks do not go in the right direction.

Also, I need information-dense design, not whitespace-dominated design. Some of us build complex apps that display a lot of information and need tightly packed UI.

This is not hypothetical: I really do need to replace Semantic UI with something that is maintained and will work better on mobile screens. At a quick glance, my code has several thousand places where Semantic UI tags are used. If somebody picked up Semantic UI, started maintaining it without turning it into a JavaScript framework, and offered a $249/month subscription, I'd pick it up.
