Custom classes to checkout fields

[wdmarketLV]

Hello, I am using firecheckout.
I added a custom address field.
I need to style it, but I cant, because it doesn't have a class, all other fields is possible,
what I need to do to add class checkout field?
Regards

You can use the CSS attribute selector:

input[name="company"] {
    //your styles here
}
