Bento UI

"Everything in its right place. A highly structured, modular grid of distinct compartments."

When to Use

Use this sub-style when the user's request matches the aesthetic described above. This is a child reference of the design-it skill and is not meant to be triggered directly.

Core Principles

1. Strict Grid Structure: The entire UI is built on a responsive, multi-column grid (usually 3x3, 4x4, or irregular masonry).
2. Rounded Compartments: Every distinct piece of content lives inside a card (compartment) with consistent, usually large, border-radius.
3. Equal Spacing: The gap between compartments must be perfectly consistent everywhere.

Visual DNA

• Colors: Highly adaptable, but looks incredibly premium with Minimalist Slate or Yacht Club. Often uses a slightly off-white or light gray background to make the white compartments pop.
• Typography: Apple-esque (e.g., SF Pro, Inter). Headlines are usually bold and placed at the top-left or bottom-left of each compartment.
• Visuals: Often relies on high-quality, edge-to-edge images or single, large 3D icons inside specific grid cells to break up text-heavy cards.

Web Implementation

• CSS Grid is mandatory. Flexbox is too difficult to maintain the strict 2D structure.
• CSS Example:

.bento-container {
  display: grid;
  grid-template-columns: repeat(4, 1fr);
  grid-auto-rows: 200px;
  gap: 24px;
  padding: 24px;
  background-color: var(--bg-primary); /* Slightly darker than cards */
}

.bento-card {
  background-color: #fff;
  border-radius: 32px; /* Very large border radius */
  padding: 32px;
  box-shadow: 0 4px 24px rgba(0,0,0,0.04);
  /* Optional: subtle 1px border for crispness */
  border: 1px solid rgba(0,0,0,0.05);
  
  display: flex;
  flex-direction: column;
  justify-content: space-between;
}

/* Creating spans for different bento sizes */
.bento-span-2 { grid-column: span 2; }
.bento-span-2-row { grid-row: span 2; }
.bento-large { : span ; : span ; }

App Implementation

SwiftUI

struct BentoGrid: View {
    let columns = [
        GridItem(.flexible(), spacing: 16),
        GridItem(.flexible(), spacing: 16)
    ]
    
    var body: some View {
        ScrollView {
            LazyVGrid(columns: columns, spacing: 16) {
                // 2x1 Span (Full width)
                BentoCard(title: "Hero", color: .blue)
                    .frame(height: 180)
                
                // 1x1 Spans
                BentoCard(title: "Stats", color: .green)
                    .frame(height: 180)
                BentoCard(title: "Graph", color: .purple)
                    .frame(height: 180)
                
                // 1x2 Span (Tall)
                BentoCard(title: "Activity", color: .orange)
                    .frame(height: 376) // (180 * 2) + 16 spacing
                
                // 1x1 Spans next to the tall one
                VStack(spacing: 16) {
                    BentoCard(title: "A", color: .pink).frame(height: 180)
                    BentoCard(title: "B", color: .cyan).frame(height: 180)
                }
            }
            .padding(16)
        }
        .background(Color(.systemGroupedBackground))
    }
}

 :  {
     title: 
     color: 
     body:   {
        (cornerRadius: )
            .fill((.secondarySystemGroupedBackground))
            .overlay(
                (title).font(.headline).foregroundColor(color),
                alignment: .topLeading
            )
            .padding()
            
            .shadow(color: .black.opacity(), radius: , x: , y: )
    }
}

• Use LazyVGrid for uniform grids.
• For complex irregular bento layouts (like 1x2 spans), you often have to mix VStack and HStack inside the grid cells to fake the spans.
• Maintain absolute consistency with cornerRadius (usually 24-32pt) and spacing (usually 16pt).

Flutter

import 'package:flutter_staggered_grid_view/flutter_staggered_grid_view.dart';

class BentoScreen extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      backgroundColor: Colors.grey[100],
      body: SingleChildScrollView(
        padding: const EdgeInsets.all(16),
        child: StaggeredGrid.count(
          crossAxisCount: 4, // 4 columns total
          mainAxisSpacing: 16,
          crossAxisSpacing: 16,
          children: const [
            // 2x1 (Full width in a 2-col layout, spans 4)
            StaggeredGridTile.count(
              crossAxisCellCount: 4,
              mainAxisCellCount: 2,
              child: BentoCard(title: 'Hero'),
            ),
            // 1x1
            StaggeredGridTile.count(
              crossAxisCellCount: 2,
              mainAxisCellCount: 2,
              child: BentoCard(title: 'Stats'),
            ),
            // 1x1
