I have made a new numeric field successfully (based on text field) but where do I change the class name that appears in the html. I need to be able to target this field specifically in the .css file and right now it has a class of "field text" -- as do all other text fields. I can see no .ss files that controls this. Do I need to make a new file .ss? If so, what do I call it and what should it contain?
