Overview
What problem does it solve?
Carbon applies IBM’s design language through reusable foundations, components, patterns, content guidance, and maintained code packages.
What the system documents
- Use a single primary button per page context and lower-emphasis variants for other actions.Supporting reference: Button usage
- Use links for navigation and buttons for actions.Supporting reference: Button usage
- Carbon component accessibility status distinguishes automated, keyboard, advanced-state, and manual screen-reader testing.Supporting reference: Accessibility
Why this system is worth studying
Carbon is especially valuable for enterprise interfaces because its documentation confronts density: structured forms, data tables, multi-step workflows, system feedback, complex component combinations, and code-level status.
Carbon’s enterprise density and IBM visual language can be more machinery than a small consumer product needs. Material or native platform guidance may offer a lighter starting point.
