Core Laws

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

12. "Wow Factor" Checklist

• Generous whitespace
• Subtle depth/​dimension
• Smooth animations
• Security cues
• Social proof
• Clear value proposition
• Social proof
