We would like to change the HTML created for some but not all of out fields in the checkout pages. Is this possible, and if it is, where do I start? I have looked at many TPL files and it seems all the HTML is generated and so I can't see how I could change a single field.
(We want to do this to add some friendly validation on some fields, particularly those used for credit card processing. At the moment, we can accept a surname which is too long for the credit card processor).
Thanks, Mike
