I was wondering whether it is possible to modify the css files so that another language can be displayed when either error messages or warnings are shown (for example at failure to tick all checkboxes or to fill a field). I have browsed through the css_includes section but have no clue what should be added so that this option could be possible. I guess that adding something to the Form.css or to Message.css.
Do you have any ideas or tips for me?
Thank you so much for your help!
