I'm using shadcn's button component which includes variants, the code looks like this:
import * as React from "react"
import { Slot } from "@radix-ui/react-slot"
import { cva } from "class-variance-authority";
import { cn } from "@/lib/utils"
const buttonVariants = cva(
"inline-flex items-center justify-center gap-2 whitespace-nowrap rounded-md text-sm font-medium transition-[color,box-shadow] disabled:pointer-events-none disabled:opacity-50 [&_svg]:pointer-events-none [&_svg:not([class*='size-'])]:size-4 [&_svg]:shrink-0 outline-none focus-visible:border-ring focus-visible:ring-ring/50 focus-visible:ring-[3px] aria-invalid:ring-destructive/20 dark:aria-invalid:ring-destructive/40 aria-invalid:border-destructive",
{
variants: {
variant: {
default:
"bg-primary text-primary-foreground shadow-xs hover:bg-primary/90",
destructive:
"bg-destructive text-white shadow-xs hover:bg-destructive/90 focus-visible:ring-destructive/20 dark:focus-visible:ring-destructive/40",
outline:
"border border-input bg-background shadow-xs hover:bg-accent hover:text-accent-foreground",
secondary:
"bg-secondary text-secondary-foreground shadow-xs hover:bg-secondary/80",
ghost: "hover:bg-accent hover:text-accent-foreground",
link: "text-primary underline-offset-4 hover:underline",
},
size: {
default: "h-9 px-4 py-2 has-[>svg]:px-3",
sm: "h-8 rounded-md px-3 has-[>svg]:px-2.5",
lg: "h-10 rounded-md px-6 has-[>svg]:px-4",
icon: "size-9",
},
},
defaultVariants: {
variant: "default",
size: "default",
},
}
)
function Button({
className,
variant,
size,
asChild = false,
...props
}) {
const Comp = asChild ? Slot : "button"
return (
(<Comp
data-slot="button"
className={cn(buttonVariants({ variant, size, className }))}
{...props} />)
);
}
export { Button, buttonVariants }
However only the "ghost" variant is working properly, other variants appear as a white button, and the issue seems to be the "primary" color not being recognized. Other components without variants do recognize the primary color though.
This happened after I added @import "tailwindcss"; to my index.css file, because without it the tailwind classes (i.e.: text-4xl`) were not being applied.
Note: I'm using tailwindcss V4.
My current structure looks like this:
- src/
- index.css
- components/
- ui/
- button.jsx <- shadcn component
- SomeComponent.jsx
I'm very new to web development, so I appreciate any help!
Edit:
My index.css file:
@import "tailwindcss";
@tailwind base;
@tailwind components;
@tailwind utilities;
@source "../components";
/* @plugin "tailwindcss-animate";
@custom-variant dark (&:is(.dark *)); */

The cn function being used by the button:
import { clsx } from "clsx";
import { twMerge } from "tailwind-merge"
export function cn(...inputs) {
return twMerge(clsx(inputs));
}
You can remove the css for button here:
@media (prefers-color-scheme: light) {
:root {
color: #213547;
background-color: #ffffff;
}
a:hover {
color: #747bff;
}
/* button {
background-color: #d36c6c;
} */
}
