I'm trying to add the bootstrap class "form-control" to all the woocommerce address fields under my account and also when you do a check out.
Basically I want to add the class "form-control" to all the billing address and shipping address input fields. I've tried everything and also looked at the documentation here https://docs.woocommerce.com/document/tutorial-customising-checkout-fields-using-actions-and-filters/
I also found another post Add custom css class to WooCommerce checkout fields
I've tried everything but nothing seems to update the fields or add a class. I've tried just adding one of the examples in my functions.php file but it doesn't seem to work.
Would anyone be able to help me?
Thank you in advance.
