Until somebody has another similar box so they reuse login-box a bunch in your application, then you realize that they actually need to be customized and have to tear it all apart.

Tailwind doesn't make you copy and paste, it moves the reuse of styles out of CSS which sucks at managing reuse into whatever HTML building system which likely has some concept of reusable views.

Then they make `.box` and include it as a mixin. Like CSS developers have done for a decade (and which tailwind itself does using PostCSS)

Yes it does. Moving all styles into individual elements without reuse is copy and paste.

Tailwind all but assumes you will be using something that allows you to extract HTML into components, be that something like React or Vue, or classic partials in a server-side templating language like Twig. You reuse the entire component, rather than just the CSS, which IMO is far better aligned with how apps are actually built.

So no, using Tailwind classes is no more copy pasting than typing CSS in full into a separate stylesheet is copy pasting.

You’re misunderstanding the relationship between components and styles.

Login box and messages are separate components, but they share padding metrics, border styles, a palette, etc.

Have you used tailwind before?

I use Tailwind almost exclusively these days.

My argument is that using the “mr-1 pl-2” utilities on both a login box and a message would be no more copy pasting than creating a stylesheet with “.login-box { margin-right: 0.25rem; padding-left: 0.5rem; }” and “.message { margin-right: 0.25rem; padding-left: 0.5rem; }”.

And if you’re suggesting that you would create a single CSS class with those properties to apply to both the login box and the message, then it’s my opinion that that is a broken abstraction that falls apart as soon as your designer asks if you can make the spacing in the login box a little looser.
