Introducing custom CSS for AuthKit: Unlock full styling flexibility

The introduction of custom CSS support in the WorkOS AuthKit branding editor enhances the visual customization capabilities for teams, allowing them to apply their own CSS styles to AuthKit components while maintaining security and stability. Previously, AuthKit offered simple global branding options like colors and logos, which were suitable for quick and cohesive branding but insufficient for teams with complex visual guidelines. The new feature enables precise styling of individual UI elements, global styling across all AuthKit pages, and the use of remote images for backgrounds, ensuring a consistent authentication experience. Additionally, the update includes a targeting tool that simplifies element customization within the editor and a smarter back button that preserves unsaved changes, encouraging experimentation and making the editing process more intuitive and efficient.
