How to use the animate() function?
I tried this solution: Correct way to animate box-shadow with jQuery
like
...
  .animate({
    marginTop: '-20px',
    marginLeft: '-20px',
    width: '200px',
    height: '200px',
   'boxShadowX': '10px',
   'boxShadowY':'10px',
   'boxShadowBlur': '20px'
  }, 200);
...
but it doesn't work...
