There are a few different ways that you can customize the checkout layout in WooCommerce. One way is to use a plugin like WooCommerce Checkout Field Editor.
This plugin allows you to add, edit, and delete fields on the checkout page. You can also rearrange the order of the fields.
Another way to customize the checkout layout is by editing the code directly. You can do this by going to Appearance > Editor and selecting the WooCommerce template files you want to edit from the dropdown menu.
Keep in mind that if you make any changes to these files, they will be overwritten when you update WooCommerce. So, it’s always a good idea to create a child theme first.
And finally, you can also use CSS to style the checkout page. For example, you could add some custom CSS to change the color of the buttons on the checkout page.
So, there are a few different ways that you can customize the checkout layout in WooCommerce. Which method you choose will depend on your own individual needs and preferences.
