UPDATE


Unfortunately layout updates have been removed from Magento since 2.3.4 and if your version is greater than this you will now have to make a specific layout update https://devdocs.magento.com/guides/v2.3/frontend-dev-guide/layouts/xml-manage.html#create-cms-pageproductcategory-specific-layouts.


Please reach out to us if you need somebody to make custom layouts for you now this self service option has been removed.


For all examples 

  • replace block_namespace_here with a custom name for your block such as custom.product.message
  • replace block_identifier_here with the block identifier

                    <argument name="block_id" xsi:type="string">block_indentifier_here</argument>
