Core Rules

1. Mobile-First Always

Start with mobile layout, enhance upward
Every grid must collapse to single column
Touch targets minimum 44x44px
Test on real devices, not just simulators

2. Typography Matters

Avoid generic fonts (Inter, Roboto, Arial)
Use dramatic size jumps (2x+), not timid increments
Body text 16-18px minimum
See typography.md for specific recommendations

3. Color with Purpose

70-20-10 rule: primary, secondary, accent
Commit to light OR dark — no muddy mid-grays
Never solid white backgrounds — add depth

4. Feedback on Every Interaction

Acknowledge taps within 100ms
Optimistic updates for instant feel
Loading states for operations >1s
Preserve user input on errors

5. Accessibility Non-Negotiable

Color contrast 4.5:1 (text), 3:1 (UI)
Focus states on all interactive elements
Semantic HTML (nav, main, section, article)
Keyboard navigation works for everything

6. Performance from Start

Lazy load below-fold content
Image placeholders prevent layout shift
Code split heavy components
Target LCP <2.5s, CLS <0.1

7. One Memorable Element

Every page needs one unforgettable design choice
Typography treatment, hero animation, unusual layout
Timid designs fail — commit to an aesthetic

Frontend Traps

Trap	Consequence	Fix
Generic fonts	Looks like every other site	Use distinctive fonts
Solid white backgrounds	Flat, lifeless	Add gradients, grain, depth
Mobile as afterthought	Broken for 60% of users	Mobile-first always
Form error clears input	User rage	Preserve input, highlight error
No loading states	User thinks broken	Show progress immediately
Timid type scale	No visual hierarchy	Use 2x+ jumps for headlines

🤖 AI 評測

這個Skill質量較好，它把前端介面設計要做的事講得很清楚，從怎麼選字型顏色、怎麼做動畫效果、到怎麼適配手機螢幕都有涉及，還給了可以直接用的程式碼示例。優點是實用、規則明確，比如專門強調不要用那些爛大街的字型、要給背景加層次感等；缺點是一些小細節說得不夠詳細，而且有個小問題——文件裡版本號對不上，可能讓使用者困惑。總體適合需要做漂亮前端介面的人參考。
