  1. // lazy hack for css
  2. document.body.innerHTML = `
  3.   <style> 
  4.     button { 
  5.       cursor: pointer; 
  6.     }
  7.     .red { 
  8.       background-color: red; 
  9.     } 
  10.   </style>
  11. `
  12.  
  13. const btn = document.body.appendChild(
  14.   Object.assign(
  15.     document.createElement('button'), 
  16.     { innerText: 'click me' }
  17.   )
  18. )
  19.  
  20. btn.addEventListener('click', e => {
  21.   e.target.classList.toggle('red')
  22. })
