Lovely. Verbosity aside, now on top of knowing CSS you need to learn another hierarchical system within class names.

Oh yeah, when I open a typical big project with Tailwind I always love to see some:

Before Tailwind, every web designer I’ve ever worked with invented their own version of this.

Yes, CSS in theory is powerful and has everything necessary to avoid using Tailwind, but in practice CSS has a major flaw: You’re almost required to build a semantic model to get the full power. But this ignores that designers are working with mood and emotion just as much as document structure and information architecture. Capturing these more nebulous concepts as logical semantic rules is very difficult if not impossible. Tailwind just codified what everyone already did: Skip the semantic dance (“Making that text bold would be really cool, but what does it mean to be cool, as a general rule?”) and just create semantic rules like “bold” and “red”.

Doesn't react with styles components (or CSS in js) avoid this? I define reusable components, drawing from a shared theme object. But the styles are still css

This is the complete opposite of what good CSS is supposed to be. The class name is supposed to tell you what it is not how it looks like. Anyone remember CSS Zen Garden?

omnimus 8 hours ago

Tailwind goes into crazy extreme so people can copy paste whole complex components and they work. That’s why you can dunk on these verbose examples.

This is not how custom functional css codebase looks. In custom projects you change the system/configuration to fit the project. You create your own utilities for example you wont have “text-lg sm:text-xl font-semibold tracking-tight” but will have class “font-heading-2”. Similarly you will create button/input classes that have you basic styles.

Generally you start with just simple utility classes inside html and go from there and where it make sense or its too complex you separate to more complex class. You end up with short css file that only has these special components and none of the basic stuff.

For most elemets it ends up like “flex justify-center gap-4”. In BEM i have to invent “nav-secondary__header” put it in correct place and hate myself when i need to change it to “flex justify-beween”.

Tailwind popularised functional css but is also aimed at masses/noobs. Somehow some of those concepts also resonated with some experienced users.

I've worked in many different FE codebases with a variety of CSS "strategies".

This sort of thing is objectively ugly and takes a minute to learn. The advantages of this approach I found is two-fold

1. You can be more confident that the changes you are making apply to only the elements you are interested in changing

You are modifying an element directly. Contrast with modifying some class that could be on any number of elements

2. You can change things around quite quickly

Once you're well familiar with your toolset, you know what to reach for to quickly reach a desired end state

Can I copy some random HTML+CSS snippet from the internet and be sure that it'll look exactly the same in my project and that no existing CSS is going to overwrite it?

I'm never gonna argue learning proper CSS wouldn't be better, but Tailwind is by far the path of least resistance for someone that has no interest in writing frontend for a living. It's like putting legos together, it requires very little thought to get from nothing to a decently looking website.

This is objectively good clean code when you develop it.

Because most of those classes are per component.

If you have a single card component defined with these classes, and then repeat it 20 times on the page, then of course the output will look like a giant mess.

> How did tailwind get so popular?

- quick to understand and get started with

- much cleaner for components than the variety of CSS-in-JS libs

- (mostly) do not require fighting CSS with BEM-style atrocities

- come with nice default styles and colors that can be easily changed and extended

> Learn plain CSS. It's really good now

CSS is okay now. We only just got nesting and scoping

emmanueloga_ 16 hours ago

In real projects I typically group the classes in a way that makes it easier to read, something like this:

    <div class={tw(
      "block",
      "transform transition-all",
      "bg-white ring-1 ring-black/5 rounded-xl shadow-2xl",

      "max-w-3xl mx-auto overflow-hidden",

      "group-data-closed/dialog:opacity-0",
      "group-data-closed/dialog:scale-95",

      "group-data-enter/dialog:duration-300",
      "group-data-enter/dialog:ease-out",

      "group-data-leave/dialog:duration-200",
      "group-data-leave/dialog:ease-in"
    )}>
        ...
    </div>
I currently do this manually but it would be nice to have some tooling to automate that kind of format.

I do this to this day, when I’m writing manual vanilla CSS. I group spacings, fonts, texts, borders etc together so it is easier for me to debug without using too many tools.

I have a feeling that Tailwind started with a good intention to be a utility classes CSS framework, akin to “Bourbon on Steroids”, but people began to accept and use their prototype/sample/example codes way better than they had intended, and they ran with it.

I stumbled on Tailwind in 2018 and introduced it to a team looking to revamp a pretty massive project. I remember that the initial proposal I made was to treat it like Bourbon[1] and write classes that build on Tailwind’s utilities. That way, you can still have `.button`, `.button-primary`, and `.button-primary__accent` etc without the cryptic classes in the HTML.

However, after reading Tailwind, the team found it much easier to write the pre-built classes and stack them as they progressed. And it worked; if I don’t care about how the code is written, things were consistent. It reminds me of “Pixel Perfection” before the responsive design era, when things looked as designed in Photoshop and printed for clients during presentations.

Dont’t forget Tailwind is popular because people can copy paste chunks of HTML. Selling premade HTML is how Tailwind is funded.

It is also pretty good configurable utility framework but that is secondary and new version 4 is worse at customisation.

So people are moving to https://unocss.dev/ with tailwind naming conventions.

Tachyons CSS was also around at the same time but Tailwind had simpler naming conventions so instead of `br4` you had `rounded-lg`.

Some people (I suspect a lot of young and motivated developers) think that UI development should be easy and elegant.

But consider that a UI is 100% state management and side effects (so fundamentally imperative and asynchronous). On top of that it takes about three revisions for any tool to require bespoke display of something (everybody has an opinion). They also bring a layout engine which is best expressed in constraints.

And somehow we are trying to shoehorn all this into a functional paradigm.

We use web components at the hook for my company's advertising code but I've found them pretty thoroughly disappointing, personally. They make it simple to trigger code execution but their API isn't really that good

spankalee 20 hours ago

The whole point is to make it simple to trigger code and to be interoperable. Then you write whatever code you want to implement the component.

Web components are not analogous to frameworks because frameworks tightly couple the component interface and lifecycle hooks with the component implementations. Those are properly decoupled in web components and you bring whatever rendering layer you prefer.

combyn8tor 18 hours ago

This is great. Last time I looked into this UI component world I was surprised the popular UI libraries weren't all 'headless' at their base. Web components have been around a long time now. What was stopping this approach?

There are so many framework specific libraries like shadcn, and the community set about building half finished conversions for different frameworks like Vue, which are always several iterations behind and don't really work properly. They have their own version of the docs and it all relies on a specific version of Vue and a specific version of Tailwind and whatever else. It's an abomination.

Start with headless UI as a base and then build wrappers for specific frameworks if you really feel the need. But the wrappers should be syntax sugar only and linked directly to the base library.

I'm sure it's all more complicated than that but a man can dream.

chrismorgan 13 hours ago

Put simply: if you’re using something like React, Vue, Svelte, whatever, then Web Components are strict overhead in terms of bundle size and runtime overhead. And when there’s impedance mismatch between the two worlds, which I hear is particularly common in React (can’t attest it personally, I don’t use React), you have to compromise on functionality or ergonomics, or else do fancier bindings, at which point why even bother with Web Components?

It will also commonly not play nicely with some more advanced aspects of the frameworks, like server-side rendering will probably suffer (depending on how exactly things are done).

In a world where React is dominant and you’re wanting to use React yourself, targeting Web Components just doesn’t make sense.

Then “headless” makes it worse. The more comprehensive implementations have a lot of overhead.

Just a reminder that jQuery was once dominant, too.

combyn8tor 11 hours ago

Here's my put simply:

We've got some UI components built with html, CSS and JavaScript. They use web standards.

We want to add them into web frameworks that are built in JavaScript. They are built for html, CSS and JavaScript.

No need to overcomplicate things.

And for a universal component library I'll happily accept 7kb extra overhead in my 4mb React slop website

The world would be a significantly better place if someone could throw a small mountain of money at the Tailwind folks so that they can stop worrying about money and simply make the full tailwind experience freely available. There are so many lost opportunities for deep integration with other projects.

Kind of like how Jeff Bezos threw a bunch of money at 37signals at some insane valuation, which helped them completely avoid the VC trap.

abxyz 21 hours ago

Worried about money? They are already rich beyond their wildest dreams. They are, reasonably, excited about growing and expanding and building a company that does much more, but that is not driven by a need for money, it is driven by their ambition.

edit: I can’t speak for Adam etc., this is just my impression. My impression is that they want to build a business of which tailwind (the open source project) is one part. I think that regardless of money in the bank they would want to have revenue generating projects. Laravel is a good comparable.

Fwiw I feel like their components are something I'd be less likely to want to pay for now that you can generate tailwind components so easily with ai. I guess now that I think of it I actually paid for them back when it was called Tailwind UI, but instead of using them I'm just telling claude to generate a UI for me, which has the advantage that there's no licensing issues. It'll be interesting to see how their business does going forward

nikkwong 18 hours ago

How has shipping high quality products using AI generated tailwind components actually been working for you? I think the problem that I and many others have/had, is that it can certainly build a few components that look good in isolation, but it doesn’t do a good job at maintaining a cohesive theme/idea across many different page sections/components etc. I built blendful [0] to solve this, and sort of lost interest when LLMs became increasingly capable. However, seeing them not making any gains, really, on visual cohesion between sections and components provoked enough excitement to continue working on it this year.

We will see how long it takes for LLMs to make headway in this area specifically.

The “full Tailwind experience” is already freely available. What “lost opportunities for deep integration” is a frontend CSS framework missing?

Tailwind Plus (the commercial product) is like buying an off-the-shelf template. It’s just a collection of themes and pre-built components — useful for devs who want to get started quickly on a project, but it’s cookie-cutter and can easily be replicated by anyone with Tailwind itself.

vinnymac 21 hours ago

There are devs who think the currently available HTML elements are all we needed. But there are many more that believe we are missing primitives that Tailwind (and others) is attempting to solve for.

All reusable web components could be described as an optionally themed pre-built component. That's kind of the point.

I no longer see value in prebuilt templates since LLMs can put things together sufficiently well for prototyping. Even when using templates before you still needed to customise them. Feels like we are going through a transition period.

This is Vue support.

With so many frameworks out there it's infeasible to build custom wrappers for them all. With web components they can build once, and work everywhere. It's only up to the frameworks to make sure they have great web components support (which just means great HTML support).

skrebbel 20 hours ago

Vue has great web component support. Even React 19 (finally!) does.

Web components are a mess but this is a great application of them: shipping reusable components that work in all frameworks. It's the one and only killer application of web components.

Frankly I'm surprised they're marketing this as "for vanilla javascript" and not as a "now supports all frameworks" type positioning.

ayhanfuat 20 hours ago

That’s not really the point. Tailwind UI depends on Headless UI. Headless UI had both Vue and React packages. The Vue package was abandoned. Many are in the process of finding workarounds for the issues or moving to another library. This new shiny thing can be used in Vue, sure. I know better now to not build anything on top of it though.

Yeah this seems like an odd thing to paywall. In the web dev world where everything is free, it's a pretty crazy ask to ask people to tie themselves to a UI framework where I guess you're forever paying a subscription just to continue using the framework?

It's like putting if postgres expected you to pay them a monthly fee.

edit: I see now their pricing is one-time perpetual access. Still, I'm genuinely curious how well this model works.

I still can't justify using Tailwind. It's not that I don't like it, but I find CSS does everything I need and more, and I do some pretty complex styling and animations in CSS.

Since you are asking about other approaches, I've been doing some interesting and simple custom elements with my Knockout-inspired view engine [0]. I built an open source MPA application with a bunch of them [1]. I even gave a brief presentation on it [2] (each PR starting with #2 is a "slide"; I presented it in a "Presentation" profile for VS Code opening the numbered files in order, with the Live Preview extension side-by-side with a simple git alias to jump to "slide" merge commit based on PR number; I thought it went well to show off Developer Experience).

My biggest advice appears to be: remember that the Shadow DOM is optional.

I love seeing a mainstream/popular project embracing web components. We've been working on a web components project for media players[1] for a while for the same reasons:

    Instead of being coupled to a specific JavaScript framework, these custom elements work anywhere you can use a <script> tag
But...React is still the elephant in the room here. Maybe TW is just in a different world if they're truly just anticipating folks using this via a `<script>` tag, but if not, very curious how they're going to deal with some of the web component (WC) stuff we've dealt with, like:

- Despite signals/promises, React 19 didn't add full support for WC. React uses a diff algorithm for reconciliation. There are some rough edges for any "complex value" cases in the incomplete solution for 19's WC support with client vs server side rendering. This results in us being required to use 'use client' for parts of our component architectures, meaning WC providers aren't able to take full advantage of SSR.

- WCs are async loading, which in combination with React can have a negative impact on performance for things like core web vitals (and the dreaded cumulative layout shift).

- WCs are just different from React patterns. Each WC creates a DOM element, but React components don't have to, which just inherently means different shapes of code.

- React focus management libraries don't play nice with WCs. We've talked to multiple devs/companies that were excited about/using WCs that backed out because of cross-ecosystem complexities like this.

- React Native is, uh....a whole thing.

On a somewhat separate note...one of my complaints about TW historically has been that it feels like "just classes" (great!), yet requires a build step (oh...). I'm a little confused to see them leaning into `<script>` tags given that, so am I just missing something?

A love letter their rails users indeed. Congratulations to the tailwind team for shipping this! Disclosure

I would like to know how they find it in comparison to a framework like react

gedy a day ago

Tailwind is fine, but I do find it humorous that they discourage wrapping up tw classes into a component class ala Bootstrap, but they wrap html up like this:

    <el-dropdown class="relative inline-block text-left">
      <button class="inline-flex w-full justify-center gap-x-1.5 rounded-md bg-white px-3 py-2 text-sm ...">
        Options
      </button>
      <el-menu anchor="bottom end" popover class="w-56 origin-top-right rounded-md bg-white shadow-lg ring-1 ring-black/5 transition transition-discrete ...">
      ...
      </el-menu>
    </el-dropdown>

Bootstrap:

    <div class="dropdown">
      <button class="btn btn-secondary dropdown-toggle" type="button">
        Dropdown button
      </button>
      <ul class="dropdown-menu">
        ...
      </ul>
    </div>
(I realize you have full control over looks with TW, but Bootstrap and others have utility classes too for the common stuff.)

The wordiness is a common complaint but TBH it's a minor issue, I do have a growing problem with using tailwind that's hidden just behind that superficial complaint though.

px-3, py-2, bg-red-400 etc. are everywhere in tailwind code and they become more or less undocumented conventions. Technically you can configure them, but practically without unintended side effects on an existing project? And if you make extensive config changes, have you just locked yourself out of the ecosystem?

I don't use bootstrap, but from a brief look at the documentation it seems much more reasonable to diverge from defaults. Looking at themes (https://themes.getbootstrap.com/) it seems more flexible than an average tailwind setup.

I agree, take a look at Bootswatch: https://bootswatch.com

I find it very nice that you can re-theme or brand your app with virtually no code or class changes.

When using Tailwind you’re likely to use something like React components, so your actual code is more likely to look like:

  <Menu>
    <MenuButton>Dropdown button</MenuItems>
    <MenuItems>…</MenuItems>
  </Menu>
which is even better than what Bootstrap provides since you get type safety for component props (and more opportunities for customization than what Bootstrap allows)

Type safety is good, but the class soup inside the components is just abysmal. And honestly, more often than not I see it spilling out of the components and onto the page layouts.

Design tokens are the one Tailwind feature I genuinely like. Everything else – kill it with fire. Just use whatever scoped CSS your stack does (<style> in Svelte/Vue, Emotion in React?).

Would this work with DaisyUI components?

nop_slide 20 hours ago

I don't see why not. I imagine the css classes in the examples are simply for styling, as long as you nest and structure the custom elements themselves correctly I imagine you should be able to style them as you wish.

I have a daisyui project too, so I might try this later.

I use DaisyUI in combination with Tailwind but it certainly has some JS backing.
