Add new region in subtheme

Hi @hopfrog → , you have to follow this steps for adding a reason.

Step 1: Define the region in subtheme -> themename.info.yml file.

regions:
header: 'Header'
sidebar: 'sidebar left'

Step 2: Adding Regions to Your Templates file like - page.html.twig (if you not find the template file in sub-theme just debug (settings.php -- debug:true;) to check which core theme in rendering on the browser and copy the twig file from there and paste it in your sub-theme template folder )

{{ page.header }}
