It's adequate for some folks who work in the same codebase, and define their own style of work. It's been a real pain for me who comes in to various codebases for short periods of time and have to read/digest/learn every single project's unique take on buttons.

class="btn btn-primary" is also pretty easy to read. But in the last couple weeks I've have to deal with both class="bg-blue-500 hover:bg-blue-600 text-white font-bold py-2 px-4 rounded-md shadow-md" style buttons and <LinkButton4 /> and <LinkButton7 /> components, both of which still seemed to be affected by another wrapping container that decided to "text-xs" everything below it, but which wasn't obvious. Trying to simply add a 'button' that had the same styles around it was far more work than it should have been.

No doubt, I'm somehow in a minority of switching between projects/codebases more often than other people. But this was much less of a problem with bootstrap and related definitions.

When you want, say, most things to share some common color/style definitions, you will still end up repeating a lot of stuff (same long string for buttons, and for headers, etc). The tailwind system gives you the option of @apply, but the tw docs are also relatively strongly against it, for ... I can't really understand the reason why.

https://tailwindcss.com/docs/reusing-styles

> If you’re going to use @apply, use it for very small, highly reusable things like buttons and form controls — and even then only if you’re not using a framework like React where a component would be a better choice.

There's some reasons listed on that page justifying "don't use @apply!" but... they don't ring all that useful to me. They do say "well, you could do it for reusable things like buttons", but those are the very things that most tailwind examples use longhand examples for.

> Yes, HTML templates littered with Tailwind classes are kind of ugly. Making changes in a project that has tons of custom CSS is worse.

There's a balance between the 'ugly' (their words) and 'tons of custom css'. Everyone's balance is different, I get it, but I'm usually having to come in after someone who was jazzed about tailwind has moved on and left me the 'ugly' (their words) mess. If every link should have "text-dark font-bold font-xs"... @apply that with an understandable name. Or document your design decisions...? But that conflicts with "ridiculously fast to build". Documenting them in an '@apply' way would let me see how you want some styles grouped together without having to scan through dozens of your components looking for a pattern.

Wouldn't you have to scan disparately located CSS files anyway? How many projects have you seen with nonsensical or clobbered classnames or conflicting rules?

Really for a lot of designs I think you can just eyeball it. If `px-4` looks about right, then use it. Otherwise you can find a similar component and hijack the exact padding if you want, or get it from the design.

You probably think @apply makes more sense because you know and like traditional CSS. You want to apply tailwind classes and condense them into a single reusable one. Tailwind asks you to think in a different way. The classes are aptly named (mostly) and granular (one class per css directive), so my knowledge of CSS felt very transferable.

  <LinkButton4 />
Imo should be

  <LinkButton variant={"homepage"} />
Leveraging something like Class Variance Authority or more simply:

  <LinkButton className="text-xl other-override-here" />
Using tailwind-merge

I have found tailwind to be indispensable, and it pairs particularly well with React.

Again, at least part of the core issues I have is coming in to other projects where each person thinks in a 'different way'. And almost all of them are simply copy/pasting loads of tailwind extended strings of stuff, then semi randomly tweaking until something looks 'ok', then moving on.

> scan disparately located CSS files anyway

usually, I encounter CSS in one of two ways:

1. a main base css file or set of files (from a framework, maybe), and then an override css file. Single override file can get hairy to look through, admittedly, but it's typically in one spot. I rarely come across projects with dozens of standalone css files.

2. 'style-in-components' - primarily in vue, because vue sfc encourages scoped styling - structure, code, style in a single file. Whether that's bootstrap styling ('btn btn-primary', etc) or tailwind doesn't make too much of a difference.

Where I've hit more maintenance issues is coming in to projects with tailwind in say, react or vue - with the 'style in components' - is that "text-xs px-1 rounded-sm bg-gray-200 inline-block text-gray-600 mb-1" repeated across multiple components, is harder to find when I want to replicate something vs just "class='tooltip'"

Of course, we're all doing it wrong, and if we all just 'think different' all the time, and spend loads of time rewriting "wrong" stuff from other people - things will be just fine. But the world I live in, and the world I see a lot of people in - is not greenfield, but brownfield, and we have to live with the decisions others made. Tailwind does not make my life any easier that way, and generally introduces more cognitive overhead earlier in a project when it comes to visual stuff.
