# Card-Based Design
> "Bite-sized consumption. Encapsulating discrete pieces of information into distinct visual containers."
## 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. **Encapsulation**: Every card is self-contained. It has an image, a title, a short description, and usually an action (like a button or a 'like' icon).
2. **Responsive Flow**: Cards easily reflow on different screen sizes (from a 4-column grid on desktop to a single column on mobile).
3. **Clear Boundaries**: Cards must visually pop off the background.
## Visual DNA
- **Colors**: Very flexible. The background should be slightly darker or distinct from the card color. **Sophisticated Neutral** works well for a premium feel.
- **Typography**: Clear hierarchy within the card (Header, Subheader, Body).
- **Styling**: Standard `border-radius: 8px` and a medium drop shadow.
## Web Implementation
- CSS Grid with `auto-fit` or a Masonry layout.
- **CSS Example**:
```css
body {
background-color: #f0f2f5; /* Standard app background */
padding: 40px;
}
.card-grid {
display: grid;
/* Auto-responsive magic */
grid-template-columns: repeat(auto-fill, minmax(300px, 1fr));
gap: 24px;
}
.card {
background: #ffffff;
border-radius: 12px;
overflow: hidden; /* Keep images inside the rounded corners */
box-shadow: 0 4px 12px rgba(0,0,0,0.08);
transition: transform 0.2s, box-shadow 0.2s;
display: flex;
flex-direction: column;
}
.card:hover {
transform: translateY(-4px);
box-shadow: 0 8px 24px rgba(0,0,0,0.12);
}
.card-image {
width: 100%;
height: 200px;
object-fit: cover;
border-bottom: 1px solid #eee;
}
.card-content {
padding: 20px;
flex-grow: 1; /* Pushes footer to the bottom */
}
.card-footer {
padding: 16px 20px;
border-top: 1px solid #eee;
display: flex;
justify-content: space-between;
}
```
## App Implementation
### SwiftUI
```swift
struct ContentCard: View {
var body: some View {
VStack(alignment: .leading, spacing: 0) {
// Image Area
Rectangle()
.fill(Color.gray.opacity(0.2))
.frame(height: 160)
// Content Area
VStack(alignment: .leading, spacing: 8) {
Text("Card Title")
.font(.headline)
Text("A brief description of the content inside this discrete card container.")
.font(.subheadline)
.foregroundColor(.secondary)
.lineLimit(2)
}
.padding(16)
}
.background(Color.white)
.cornerRadius(12)
// Clean, subtle drop shadow
.shadow(color: Color.black.opacity(0.08), radius: 12, x: 0, y: 4)
}
}
// In your view:
// LazyVGrid(columns: [GridItem(.adaptive(minimum: 160), spacing: 16)]) { ... }
```
- `VStack` inside a background with `.cornerRadius` and `.shadow` is the standard.
- Use `LazyVGrid` with `.adaptive(minimum: 160)` to automatically create a multi-column card grid that flows perfectly on iPad or iPhone.
### Flutter
```dart
class ContentCard extends StatelessWidget {
@override
Widget build(BuildContext context) {
return Card(
elevation: 4, // Handles shadow natively
shadowColor: Colors.black.withOpacity(0.4),
shape: RoundedRectangleBorder(borderRadius: BorderRadius.circular(12)),
clipBehavior: Clip.antiAlias, // Critical: stops images from bleeding over corners
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
mainAxisSize: MainAxisSize.min,
children: [
// Image Area
Container(
height: 160,
color: Colors.grey[300],
width: double.infinity,
),
// Content Area
Padding(
padding: const EdgeInsets.all(16.0),
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: const [
Text('Card Title', style: TextStyle(fontWeight: FontWeight.bold, fontSize: 18)),
SizedBox(height: 8),
Text(
'A brief description of the content inside this discrete card container.',
style: TextStyle(color: Colors.black54),
maxLines: 2,
overflow: TextOverflow.ellipsis,
),
],
),
),
],
),
);
}
}
// In your view: Use GridView.builder for the layout
```
- The native `Card` widget does almost all the heavy lifting.
- **Critical fix**: You must set `clipBehavior: Clip.antiAlias` on the `Card`, otherwise the top corners of your images will peek outside the border radius.
### React Native
```jsx
const ContentCard = () => {
return (
Card Title
A brief description of the content inside this discrete card container.
);
};
const styles = StyleSheet.create({
card: {
backgroundColor: '#FFF',
borderRadius: 12,
shadowColor: '#000',
shadowOffset: { width: 0, height: 4 },
shadowOpacity: 0.08,
shadowRadius: 12,
elevation: 4,
margin: 8,
overflow: 'hidden', // Keeps image inside borders
},
imageArea: {
height: 160,
backgroundColor: '#E0E0E0',
},
contentArea: {
padding: 16,
},
title: {
fontSize: 18,
fontWeight: '600',
marginBottom: 8,
},
description: {
color: '#666',
}
});
// In your view:
```
- Wrap everything in a View with `borderRadius` and `overflow: 'hidden'`.
- `elevation: 4` provides the drop shadow on Android, while the `shadow*` props handle iOS.
- For a Pinterest/Masonry style (columns of different heights), you must use a third-party library like `react-native-masonry-list`, as `FlatList` cannot do varying row heights in columns.
### Jetpack Compose
```kotlin
@Composable
fun ContentCard() {
// ElevatedCard provides the shadow and shape natively
ElevatedCard(
elevation = CardDefaults.elevatedCardElevation(defaultElevation = 4.dp),
shape = RoundedCornerShape(12.dp),
colors = CardDefaults.elevatedCardColors(containerColor = Color.White),
modifier = Modifier.fillMaxWidth().padding(8.dp)
) {
Column {
// Image Area
Box(
modifier = Modifier
.fillMaxWidth()
.height(160.dp)
.background(Color.LightGray)
)
// Content Area
Column(modifier = Modifier.padding(16.dp)) {
Text(
text = "Card Title",
style = MaterialTheme.typography.titleMedium,
fontWeight = FontWeight.Bold
)
Spacer(Modifier.height(8.dp))
Text(
text = "A brief description of the content inside this discrete card container.",
style = MaterialTheme.typography.bodyMedium,
color = Color.Gray,
maxLines = 2,
overflow = TextOverflow.Ellipsis
)
}
}
}
}
// In your view: LazyVerticalGrid(columns = GridCells.Adaptive(minSize = 160.dp)) { ... }
```
- `ElevatedCard` is the perfect Material 3 component for this. It handles clipping and shadows automatically.
- Use `GridCells.Adaptive(minSize = 160.dp)` in a `LazyVerticalGrid` to achieve an auto-flowing grid identical to CSS Grid `auto-fit`.
## Do's and Don'ts
- **DO**: Make the entire card clickable, not just the title or image.
- **DON'T**: Put too much text in a card. If the user has to scroll *within* a card, the card is too big.
## Limitations
- This is a styling reference and does not replace environment-specific validation, accessibility testing, or expert review.
- Ensure appropriate contrast ratios and responsive behaviors are verified separately.
