how to add custom block at shipping methods below in onepage checkout?
1. Declare module's checkout dependency
app/code/NameSpace/ModuleName/etc/module.xml
<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Module/etc/module.xsd">
<module name="NameSpace_ModuleName" setup_version="0.0.1" active="true">
<sequence>
<module name="Magento_Checkout"/>
</sequence>
</module>
</config>
2. Overwrite checkout layout
app/code/NameSpace/ModuleName/view/frontend/layout/checkout_index_index.xml
<?xml version="1.0"?>
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
<body>
<referenceBlock name="checkout.root">
<arguments>
<argument name="jsLayout" xsi:type="array">
<item name="components" xsi:type="array">
<item name="checkout" xsi:type="array">
<item name="children" xsi:type="array">
<item name="steps" xsi:type="array">
<item name="children" xsi:type="array">
<item name="shipping-step" xsi:type="array">
<item name="children" xsi:type="array">
<item name="shippingAddress" xsi:type="array">
<item name="children" xsi:type="array">
<item name="shippingAdditional" xsi:type="array">
<item name="component" xsi:type="string">uiComponent</item>
<item name="displayArea" xsi:type="string">shippingAdditional</item>
<item name="children" xsi:type="array">
<item name="additional_block" xsi:type="array">
<item name="component" xsi:type="string">NameSpace_ModuleName/js/view/checkout/shipping/additional-block</item>
</item>
</item>
</item>
</item>
</item>
</item>
</item>
</item>
</item>
</item>
</item>
</item>
</argument>
</arguments>
</referenceBlock>
</body>
</page>
3. Create JavaScript UI Component
Magento 2 checkout is manage in JavaScript (with Knockout). So you need to create a custom JS compnent. It's will create the link between checkout UI component and your custom HTML template.
app/code/NameSpace/ModuleName/view/frontend/web/js/view/checkout/shipping/additional-block.js
define([ 'uiComponent' ], function (Component) { 'use strict'; return Component.extend({ defaults: { template: 'NameSpace_ModuleName/checkout/shipping/additional-block' } }); });
4. Create HTML template
Then create the HTML template wich going to display in checkout.
app/code/NameSpace/ModuleName/view/frontend/web/template/checkout/shipping/additional-block.html
<div class="checkout-block" id="block-custom">
<p>Lorem ipsum dolor sit amet, consectetuer adipiscing elit.</p>
<p>Cum sociis natoque penatibus et magnis dis parturient montes.</p>
</div>
5. Clear cache

php bin/magento cache:clean
php bin/magento setup:upgrade
chmod -R 777 var/*
