Switching Themes For Progressive Enhancements
One of our recent projects required a progressive enhancement approach for visual changes. Instead of a full end-to-end rebuild of a Drupal theme, a progressive approach can be accomplished with theme switching. Many Drupal 8 projects leverage custom block types, Paragraphs, or Layout Builder to place one or more design components on a page. This provided the client with the ability to split up a larger architectural change into a small set of pages and components that can be gradually rolled out.
