Why This Stack Dominates
Tailwind puts CSS inline as utility classes. shadcn/ui gives you accessible components whose source lives in your repo. AI generates both fluently because the patterns are consistent.
shadcn copies source into components/ui. You own it and can edit it.
# Install shadcn CLI and init a component
npx shadcn@latest init
npx shadcn@latest add button card inputcn() merges class strings safely, handling Tailwind class conflicts with tailwind-merge under the hood.
import { Button } from "@/components/ui/button";
import { Card, CardContent, CardHeader, CardTitle } from "@/components/ui/card";
import { cn } from "@/lib/utils";
export function PromoCard({
title,
highlighted = false,
}: {
title: string;
highlighted?: boolean;
}) {
return (
<Card className={cn("max-w-sm", highlighted && "ring-2 ring-emerald-500")}>
<CardHeader>
<CardTitle className="text-lg">{title}</CardTitle>
</CardHeader>
<CardContent className="flex justify-end">
<Button size="sm">Buy now</Button>
</CardContent>
</Card>
);
}Key terms in this lesson
The big idea: Tailwind for fast styling, shadcn for accessible components you can own, and cn() to keep class lists sane.
