Get started with cssobj CDN

// Include the cssobj library
const cssobj = (() => {
  const script = document.createElement('script');
  script.src = 'https://cdn.cdnhub.io/cssobj/1.3.6/cssobj.min.js';
  document.head.appendChild(script);

  return new Promise((resolve) => {
    script.onload = () => {
      document.head.removeChild(script);
      resolve(window.CSSObj);
    };
  });
})();

// Define a CSS object
const myStyles = {
  'body': {
    'color': 'white',
    'background-color': 'black'
  },
  '.my-class': {
    'color': 'red'
  }
};

// Apply the CSS object to the document
async function applyStyles() {
  await cssobj;
  cssobj.apply(document.documentElement, myStyles);
}

applyStyles();
