Problem:
Widget styles can currently only be customized via designOption.json. Many widget structure elements cannot be targeted or modified globally.

Suggestion:
Add the ability to include a custom CSS file at the project or theme level. This stylesheet should allow global adjustments and overrides of Captivate’s core CSS.

In the long term, Captivate could – similar to the Adapt Framework – offer an open widget system, where custom or modified widgets are possible.

Custom CSS would be a useful, practical intermediate step that provides immediate benefits and paves the way toward a fully modular architecture.
