Forbidden cursor?

The css cursor: not-allowed; also works.

here is complete sample:

.not-allowed {
  cursor: not-allowed;
}

<input type="submit" value="not-allowed" class="not-allowed" disabled />

The values of cursor that represent what you're looking for are not-allowed and no-drop. These values are new to CSS3, so if you need browser compatibility you should specify an image instead.
