Modern Aesthetic (2025-2026)
Required Elements
- Bento grids (modular, varying card sizes)
- Glassmorphism (frosted glass, backdrop blur)
- Soft colored shadows (not black)
- Gradients (subtle, purposeful)
- Micro-interactions (hover states, transitions)
- Generous whitespace
Forbidden Elements
- Flat gray boxes
- Generic Lucide icons
- Pure black shadows
- Bootstrap aesthetic
- Static, lifeless UI
- Cramped layouts
Layout Default: Bento Grid
// Basic Bento structure
<div className="grid grid-cols-4 gap-4">
<div className="col-span-2 row-span-2">Large card</div>
<div className="col-span-1">Small card</div>
<div className="col-span-1">Small card</div>
<div className="col-span-2">Wide card</div>
</div>
Glassmorphism Pattern
.glass {
background: rgba(255, 255, 255, 0.7);
backdrop-filter: blur(10px);
border: 1px solid rgba(255, 255, 255, 0.2);
border-radius: var(--radius-lg);
}
Icon Rules
- NO Lucide icons (DEPRECATED)
- NO generic icon libraries
- USE AI-generated custom icons
- TWO variants: outline (UI) + duotone (brand)
Never
- Use Lucide icons
- Use pure black shadows
- Create flat, lifeless UI
- Ignore spacing scale
- Deviate from locked colors
