Quality, accessibility, and privacy audit

What you will build

Audit keyboard, zoom, responsiveness, performance, recovery, and data boundaries.

Understand the idea first

Audit keyboard, zoom, responsiveness, performance, recovery, and data boundaries.

Build it step by step

检查：键盘 / 200% 缩放 / 320px / 慢网 / 离线 / 损坏存储 / 无 Console 错误

1. Open the previous project and record its result.
2. Type the example and complete: Observe two new users complete the core task without coaching.
3. Change one input, predict, then verify.
4. Create and repair: Developer success is not user evidence; observe task completion.

Read the important lines

• Audit keyboard, zoom, responsiveness, performance, recovery, and data boundaries.
• Read input, processing, and output separately.
• Verify another input and an edge case.

Common mistakes and what to check

Practice without copying

Completion check

• I produced the required visible result
• I can explain the input, processing, and output
• I tested normal, edge, and failure cases
