A small sandbox for experimenting with CKEditor 5 theming: tweak the editor's look with CSS custom properties and see how far the UI can bend before you need a custom build.
Released: Mon Oct 20 2025
What's inside
A minimal CKEditor 5 project wired up for theme experiments - the place where I try out how the editor's CSS custom properties respond before recommending an approach. Clone it, point it at your license (a free trial works), and restyle away.
