Styling multiple alerts differently?

[itsViney]

Is it possible to add an additional class to the alert when calling alertify? I have a page that calls alertify for two different alerts and I would like to style one differently to the other, but there doesn't appear to be a way to differentiate between the two in CSS. If I had a way to add an additional unique class to each alert I would be able to do this.

It is easy to make possible. I would suggest to add these lines in line 458 of /src/js/alertify.js:

custom: function(message, class, click) {
  _alertify.log(message, class, click);
  return this;
},

This will give us the possibility to write:

alertify.custom('my message', 'my_class');
