How to edit element created in CSS with :after using jQuery?

I have created an element in CSS with pseudo-class :after. Is there a way to cha开发者_如何学Gonge it's CSS properties from jQuery?

I thinks you want

$('#object_id:after').css({
  color: blue
});

$('#my-thing').css({
  fontSize: 10em,
  width: 100px
});
