I wanted to change size of the table in checkout page [shipping label | shipping method] to 30% and 70%
But was easier to change Checkout layout to Multistep.
I found a mistake there too if I choose in woocommerce to sell only in my country. So I just added
#billing_country_field label{
visibility:hidden;
}
#billing_country_field label .required{
visibility:hidden;
}
