Web Design Guidelines

Use this skill after building or modifying web UI. It helps the agent review whether the interface is usable, readable, responsive, and polished.

Checklist

1. Layout: consistent alignment, predictable grid, no accidental crowding.
2. Typography: readable sizes, clear hierarchy, line length under control.
3. Color: sufficient contrast, semantic states, no random palette mixing.
4. Interaction: clear hover/focus/active/disabled states.
5. Responsiveness: mobile, tablet, and desktop layouts remain usable.
6. Accessibility: keyboard focus, labels, alt text, contrast, reduced motion where relevant.
7. Product states: loading, empty, error, offline, and success states exist when needed.
8. Polish: spacing, borders, shadows, icon sizes, and copy tone feel consistent.

Output

When reviewing, return: pass/fail summary, top issues, concrete fixes, and files/components likely affected.
