Usage

import { create } from 'teleport-css';
// Use your preferred hash algorithm
import fnv1a from '@sindresorhus/fnv1a';

function hashFn(value: string) {
  return fnv1a(value, { size: 64 }).toString(36).slice(0, 8);
}

const { styled, keyframes, cloneAs } = create({
  hashFn,
  context: {
    breakpoints: {
      md: '768px',
    },
  },
});

const animation = keyframes((context) => ({
  from: { transform: 'rotate(0deg)' },
  to: { transform: 'rotate(360deg)' },
}));

const Button = styled('button', (context) => ({
  animation: `${animation} 1s ease infinite`,
  backgroundColor: 'pink',
  [`@media (width >= ${context.breakpoints.md})`]: {
    backgroundColor: 'gold',
  },
}));

const ButtonAsLink = cloneAs(Button, 'a');

function App() {
  return (
    <>
      <Button
        type="button"
        css={(context) => ({
          '&:hover': {
            backgroundColor: 'lemonchiffon',
