9. UX Psychology Principles (Merged from frontend-design)
Core Laws
| Law |
Principle |
Application |
| Hick's Law |
More choices = slower decisions |
Limit options, use progressive disclosure |
| Fitts' Law |
Bigger + closer = easier to click |
Size CTAs appropriately |
| Miller's Law |
~7 items in working memory |
Chunk content into groups |
| Von Restorff |
Different = memorable |
Make CTAs visually distinct |
10. Advanced Layout Principles
Golden Ratio (φ = 1.618)
- Content : Sidebar = roughly 62% : 38%
- Heading Scale = previous × 1.618
- Spacing Scale = sm → md → lg (each × 1.618)
8-Point Grid
- Tight: 4px (micro)
- Small: 8px
- Medium: 16px
- Large: 24px, 32px
- XL: 48px, 64px, 80px
11. Visual Effects & Animation
Glassmorphism (Use with Restraint)
- Semi-transparent background
- Backdrop blur
- Subtle border
- Warning: Don't overuse; standard blue/white glass is a cliché.
Animation Timing
- Entering: Ease-out (decelerate)
- Leaving: Ease-in (accelerate)
- Emphasis: Ease-in-out
- Playful: Bounce
