### Core

```tsx
import { klass, reklass } from "@klass/core";

const button = klass({
base: "inline-flex items-center justify-center rounded-md outline-none",
variants: {
color: {
default: "bg-neutral-700 text-white",
primary: "bg-indigo-700 text-white",
secondary: "bg-orange-700 text-white",
},
size: {
sm: "px-3 py-0.5 h-7 text-sm font-medium",
md: "px-4 py-1 h-8 text-base font-medium",
lg: "px-5 py-1.5 h-9 text-lg font-semibold",
},
block: {
true: "w-full",
},
},
defaults: {
color: "default",
size: "md",
},
});

const box = reklass({
conditions: [
{
base: "",
sm: "sm:",
md: "md:",
lg: "lg:",
xl: "xl:",
"2xl": "2xl:",
},
"base",
],
variants: {
m: {
"0": "m-0",
"1": "m-1",
"2": "m-2",
"3": "m-3",
"4": "m-4",
"5": "m-5",
"6": "m-6",
"7": "m-7",
"8": "m-8",
},
p: {
"0": "p-0",
"1": "p-1",
"2": "p-2",
"3": "p-3",
"4": "p-4",
"5": "p-5",

});

button({ color: "primary", block: true }); // "inline-flex items-center justify-center rounded-md outline-none bg-indigo-700 text-white px-4 py-1 h-8 text-base font-medium w-full"
// access variant
button.g.color("primary"); // "bg-indigo-700 text-white"

box({ m: "1", p: "2" }); // "m-1 p-1"
box({ m: { base: "1", md: "2" }, p: { base: "1", md: "2" } }); // "m-1 md:m-2 p-1 md:p-2"
// access revariant
box.g.m("1"); // "m-1";
box.g.p({ base: "1", md: "2" }); // "p-1 md:p-2"
```
