"Old web" lovers, do you have a CSS library that you like?

A lot of us old-web lovers are adjacent to the "no CSS" freaks. This is despite, to the best of my recollection, the "old web" being full of wacky gifs and colorful text and image-maps and Java applets and Flash applets and gradients and gloss and even videos that you had to watch before entering a website.

But we very much like the idea of the web as a bunch of documents which are mostly HTML. But using just HTML comes with a number of problems, so you start adding CSS. If you don't write a lot of CSS, you might think it's easy, until you find that even choosing colors is impossible.

From a "minimum" CSS framework, you'd want

• "Consistency" (different browsers have different default renderings)

• "Responsiveness" (Mobile usage, but also support for the ultra-wide monitor freaks, and the tiling-wm freaks who might have your page in a column or square)

• Accessibility-respecting. It should fix problems that most browsers have when rendering raw HTML (e.g. small font size on mobile browsers) while not causing new problems. I don't know everything there is to know about accessibility.

Three very nice things, but which might be outside the understanding of "minimal", are

• "Opinionated", preferably with your opinions. (Center the main column! Avoid #000 or #fff outside bold. And so forth).

• Respect dark/light mode preference. (This can be done with just CSS, but a small JavaScript override is also welcome).

• Color palettes. Choosing colors that work well together is a combinatorically hard problem. Modern HTML has nice features like variables and color interpolation. Color highlighting, links (new, visited, and hover), and buttons are the places I most expect to see color.

And there are tons of these. Pico CSS, Milligram, mini.css, Neat, etc. with varying degrees of "minimalness". Ideally, it should be small enough that it makes more sense to copy-and-paste the CSS rather than some npm install.

Not in consideration, but things I've been looking at, are Bootstrap, Svelte, and Oat. Three different things but they can all be used to make Web Sites.
