Is it possible to arrange the checkout in 2 columns?
Yes, here is the simple snippet which helps to add 2 columns. This is useful when you want to shorten some fields in the billing form. So let’s give it a try.
Please practice this code in your child theme style.css file
@media (min-width: 993px) {
.woocommerce-checkout .col2-set .col-1 {
width:100%;
}
.woocommerce-checkout .woocommerce-billing-fields h3 {
margin-top:40px;
}
.woocommerce-checkout .col2-set,
.woocommerce-checkout .col2-set {
width:42%;
float:left;
}
#order_review_heading,
.woocommerce-checkout #order_review,
.woocommerce-checkout #order_review {
float:left;
width:42%;
margin-left:6%;
}
.woocommerce-checkout h3#order_review_heading {
margin: 18px 55px !important;
}
}
