How to create a Subtheme in Drupal using Bootstrap and the Barrio?

We must run the following steps in order to create a subtheme in Drupal using Bootstrap and Bario:

1. Verify that Drupal is set up on the local system.

2. Set up the Barrio theme on Drupal.org. We have two options for doing this: manually adding it to the themes directory or using the control interface.

3. Make a new directory for the subtheme inside the themes directory of the Drupal setup. For instance, we would make a directory called my_subtheme if we wanted to call the subtheme “my_subtheme”.

4. Make a file called my_subtheme.info.yml inside the subtheme directory. The name, description, and dependencies of the subtheme are all included in this file.

5. Make a file called my_subtheme.libraries.yml inside the subtheme directory. This file contains the libraries that the subtheme will use.

6. If we need to add or modify any custom PHP functions, we can create a file called my_subtheme.theme inside the subtheme directory.

7. In order to enable the subtheme, go to the Appearance page in the Drupal interface.

8. Now that we have modified the CSS files, templates, and other theme files of the subtheme, we can alter its view as desired. Don’t forget to empty Drupal’s cache following the change.
