The constant push with SAAS and cloud-based data and all the rest, just makes me think we're heading back towards a terminal/mainframe environment and soon we'll be "consuming" the Internet in the same way we consume interactive Cable TV.
Unfortunately, this does not give the ability to do system-wide restyling of the kind _trampeltier mentioned. Despite professions to the contrary, almost nothing whatsoever on the web is in any way semantic. Each website is its own assortment of CSS hacks hooked up to a tree of randomly nested, randomly named divs. You can't just write one style that says "please stop with the whitespace around media boxes", you have to unbreak each site individually, because a "media box" isn't really a website-independent thing, and neither is a button.
FWIW, I still recommend installing Stylus instead of Stylish - the difference is that at some point, Stylish changed owner and acquired analytics; Stylus is a fork that's free of privacy-invading antifeatures.
They insist on doing everything themselves and ignoring all standards which just ends up looking ugly and broken.
One of my main passions in theming is making your entire system look cohesively styled. Hell, I’d rather have standard Windows look but every program using the system UI so at least it all looks the same. I despise Spotify, Discord, and all Electron apps for this reason. They look so amateurish.
On the bright side, with native Linux you can customize everything. It's so fun to customize your window manager, status bar, etc. and have everything look and work exactly how you want.
It is just what I needed.
Under Windows I created and used a "dark" theme in 1991, nearly identical to what the canned Mac OS "dark" one is today. Used it well into the 2000s.
Microsoft REMOVED that capability in what, Vista? And now that everyone has finally realized how stupid inverse color schemes are, the color-scheme editor is totally gone from Windows. It was in there for a decade and a half or more.
They also removed the "blue background, white text" option from Word, just a couple years ago.
Windows is an execrable mess now.
Apple, which forced an inverse color scheme on its users for 30+ years, has at least granted them some relief. But it's still pathetic to hobble a OS's UI with hard-coded color schemes.
also white text on blue- ouch.

For an even more WTF experience, look at how CSS had defined how web apps could use the system-defined colours for UI elements, but then it was deprecated due to a very thin "insufficient" and "security/privacy" argument:
https://www.w3.org/TR/css-color-4/#deprecated-system-colors
Obviously they could be made sufficient (imagine if JS was deprecated because it was deemed "insufficient" for making applications behave natively...), and things like Electron could use them without worrying about "security" since it's not in pages served over the network.
(That "security/privacy" argument is really thin, especially when considering how much less customisable the colours have become in newer OSs!)
The ultimate state of perfect security for a system is a dead rock. Everything that's interesting and useful can only happen in the state of some lack of security.

The whole point is that application developers don't even have to care about it if they do things right, by using the OS's UI controls they will automatically be drawn with whatever colour the user has set.
You could tell the ones who didn't know what they were doing by the invisible text littering their UIs under some color schemes. This continued into the Web era. There were tons of defective sites that overrode your system background color with a hard-coded white background, but didn't bother setting the text color to black.
The result was invisible text on any system with a "dark" (non-inverse) color scheme. DUHHHH
There are probably still millions of such sites today, but now UIs are so gimped that they hide the defect.
But the file dialogs have black text. You can hardly read anything
