💫 Particle Movement Patterns
Normal State: No Particles
Hover State: 12 Particles Flying
Particle positions at different angles:
P1 (0°)
↑
|
P4 ←--( • )--→ P2 Center
|
↓
P3 (180°)
Each particle:
- Starts at center (opacity: 0)
- Moves outward along its angle
- Reaches max distance (80-100px)
- Fades out at edges
- Duration: 3s loop
Particle Pattern:
Angular distribution (12 particles):
0°, 30°, 60°, 90°, 120°, 150°,
180°, 210°, 240°, 270°, 300°, 330°
Staggered delays:
Each particle offset by 0.08s
Creates smooth orbital effect
Click State: Burst Pattern
▪ ← P1 (fast)
▪ ▪
▪ ( • ) ▪ ← Particles explode
▪ ▪ outward 2x speed
▪ ← then fade
Burst sequence:
0.0s: Particles at normal hover positions
0.3s: Particles shoot outward (2x distance)
0.6s: Particles start fading
1.2s: Particles invisible

Optimization Strategies:
-
Transform & Opacity Only
- No layout-triggering properties
- Hardware accelerated
-
Will-Change Applied
will-change: transform, opacity- GPU layer creation
-
Staggered Animation
- Spreads CPU load over time
- Smoother visual perception
📐 Geometric Calculations
Petal Position Formula:
For petal at angle θ:
x = centerX + cos(θ) * distance
y = centerY + sin(θ) * distance
Outer petals: distance = 38px (hover)
Middle petals: distance = 26px (hover)
Inner petals: distance = 16px (hover)
Particle Trajectory:
// Hover animation
translate(
cos(angle) * maxDistance,
sin(angle) * maxDistance
)
// Click burst
translate(
cos(angle) * maxDistance * 2,
sin(angle) * maxDistance * 2
)

💡 Design Philosophy
Visual Hierarchy:
- Center (Focal Point): Documentation pages = purpose
- Petals (Beauty): Organic, natural flower form
- Particles (Magic): Dynamic, alive feeling
- Sparkles (Polish): Finishing touch of elegance
Animation Principles:
- Anticipation: Slight scale-down before bloom
- Follow-through: Elastic bounce on close
- Staging: Staggered petal animation
- Timing: Slower start, faster middle, slower end
- Secondary Motion: Particles enhance main animation
Color Psychology:
- Pink/Purple: Creative, artistic, documentation
- Golden Center: Knowledge, enlightenment
- Gradient Flow: Natural, organic, alive
