Change font-size of popupdatefield with a stylename


I have a problem,I would like to change the popup datefield’s font size but if I change it was change for all the application.
I don’t know how to give a style name at the popup. I could to change textfield and button size but not the popup.

I don’t know if I’m clear.


I don’t think it is possible to add a class name to the popup div.
If nobody proves me wrong, I think you should open an enhancement request for it on the bug tracker.
