That isn't even related to Tailwind, or any other CSS framework -- just that Tailwind allows you to stay in the HTML (or component) context, without having to switch to a stylesheet there.
Your JSON comparison doesn't fit: We're talking about styling, not business logic. But if you mean that I would need to define `"userAgeOver21": true` in a JSON file instead of having some `{{ %if user.age > 21 }}` in the code, then yes, I'm firmly in the latter camp. Not having to switch context often overrules pedantic purity every time.
Indeed, not in the past 7-8 years. But we used to do it, and the outcome was great - semantic, accessible and machine-readable HTML was the norm. It’s unfortunate that we lost this in the transition to components.
But if the working groups continue to pretend HTML is for text documents instead of web applications, things will never get more semantic.
I mean, HTML is and will always forever be a system to display a few pages of text with some images thrown in. And even for that it sucks big time.
Anything standards committees have been throwing at it over the years are just haphazard hacks to make it into something it's not with no coherent goal in mind.
You know, there are still people alive who lived through this Golden Age of 10 years ago? 20 years ago? And they call bullshit on your statement.
What people misses out is CSS should be written in state-based architecture. For example for a button you have idle, hover, active, focus, focus visible, disabled states, and combinations of each button intent (default, primary, destructive, confirmation, warning) and color scheme (dark, light, high-contrast, low-contrast) states. Each of these states should enable-disable or modify some prop of the element, in most cases combination of different elements (sibling, child-parent). Trying to write them in inline classes is a PITA, especially the main concern for choosing that direction is just so we don't have a separate CSS file or need to find a name for the class (if you have a component, which Tailwind creators recommend you should, then you already need to find names for your components).
Also in addition to having separate component, component test and view/layout components; we also have separate hook files, separate state/context/store files. Even the component files doesn't encapsulate its own logic inside the same file anymore as to increase reuse of such logic. Somehow we practice separating almost every thing in the frontend to its own file, but when it comes to CSS it's too much "back-and-forth".
Maybe it's really just fundamentally different workflows - I doubt we'll reach consensus here, and that's probably okay.
> What people misses out is CSS should be written in state-based architecture
I agree with you here. That breaks down as soon as you have states that depend on the layout - saying a button should be larger on smaller devices requires adding a style into a media query that lives separate from the button styles, unless you add hundreds of individual media query blocks. Tailwind alleviates that by making "md:" a state prefix just like "hover:".
> if you have a component, which Tailwind creators recommend you should, then you already need to find names for your components
True; I need to name my button component "Button", but I don't have to find a name for the wrapper container of the icon that goes to the right side of buttons that include an icon, which it needs to create a flex context.
I guess to change these 3 property on the same condition, you need to write this TW classes (or create a "variant" in separate config file): class="dark:contrast-more:focus-visible:enabled:data[intent=destructive]:border-slate-700 dark:contrast-more:focus-visible:enabled:data[intent=destructive]:bg-slate-50 dark:contrast-more:focus-visible:enabled:data[intent=destructive]:text-gray-50"
Or am I missing something that Tailwind makes it as easy as writing these states and combinations in regular CSS (without apply, which TW creators don't recommend using)? If that example is the preferred way of writing TW, and it's only 1 condition combination, I would happily switch back-and-forth files and write regular CSS without that syntactic high-fructose corn syrup.
