Introduction
When you create a theme for Drupal 9, a recommended practice is to subtheme the core Classy theme, so you get common CSS classes and usual markup for a Drupal site. This means the Classy theme is used in the runtime as part of your theme.
The Classy core theem comes with a lot of CSS classes that can be reused.
Instead
of building on core, one may
use Bootstrap5 as
the base theme.
jQuery UI
The Drupal 8/9 core comes with jQuery UI. This is a set of user interface interactions, effects, widgets, classes and themes built on top of the jQuery JavaScript Library.
