Although I can change css complete restyle the checkout forms, this is not what I want to discuss today. What I want to achieve are:
- fix City required asterisk not showing bug
- change Address lines from full width to half width as City
To show a field in full length, Magento uses
To show a field in half length, Magento uses
So just find the right place to insert <div> and close it for Address lines, I easily style them to the same length of City.
