The checkout in Magento 2 is built up from a series of Knockout JS components which are then rendered using the Knockout JS templating system. Magneto 2 defines each one of these components and their parent/child relationship in a large XML file which can be extended or overridden in your own theme or module.
First of all, it all starts in checkout_index_index.xml.
[Magento_Checkout_module_dir]/view/frontend/layout/checkout_index_index.xmlCreate this file in your theme, and we can start:
[Magento_Checkout]/layout/checkout_index_index.xmlExample 1: Remove field from Shipping form
Define the path to a component which you are planning to remove and add this item as a child:
(in this example Fax field)
<item name="visible" xsi:type="boolean">false</item>
<?xml version="1.0"?>
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" layout="checkout" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
