│Small│Small │ 2) │
└─────┴──────┴──────┘
Template:
// 3-column bento with 192px row height
<div className="grid grid-cols-1 md:grid-cols-3 md:auto-rows-[192px] gap-4">
{/* Hero card — wide + tall */}
<div className="md:col-span-2 md:row-span-2 rounded-2xl border bg-card p-6 overflow-hidden group
hover:shadow-lg transition-shadow duration-300">

Layout Decision Framework
What is the primary content structure?
├── Data/app → Dashboard Layout
├── Marketing/landing → Hero + sections
│ ├── Feature showcase → Bento Grid
│ ├── Social proof → Masonry Cards
│ └── Stats → KPI Section
├── Content/editorial → Magazine Layout
├── Portfolio/gallery → Card Grid Masonry
└── Navigation needed → Sidebar Layout
Responsive Strategy (Always Apply)
- Mobile:
grid-cols-1, stack everything vertically - Tablet
md:: introduce 2-column, restore sidebars - Desktop
lg:: full grid complexity, max content width - Always:
max-w-7xl mx-auto px-4 sm:px-6 lg:px-8for content container
Output Rules
- Always provide the complete JSX component, not just a snippet
- Include a responsive breakdown comment at the top
- Export as a named component with TypeScript props interface
- Add
// Replace with your datacomments on data-driven sections - If animation is appropriate, note which Motion/GSAP pattern to add (handled by animation-design skill)
