Patterns worth repeating
-
Clear structure
Use headings, landmarks, and lists to make a page understandable before adding visual polish.
-
Keyboard first
Every destination and disclosure should work without a mouse or touch screen.
-
Resilient by default
Keep the core experience useful when scripts, networks, or advanced browser features are unavailable.
