```dart
WCard(
  className: 'bg-white shadow-lg rounded-lg p-4 dark:bg-gray-800',
  child: WText('Card Content', className: 'text-gray-800 dark:text-gray-100'),
);
```

## Basic Usage

`WCard` wraps a single `child` and applies Wind utilities for background color, elevation/shadow, border, border radius, and padding. Use it when you want a card surface; for a plain styled box use [WContainer](https://anilcancakir.com/wind_kit/docs/v0.0/widgets/wcontainer.md).

```dart
WCard(
  className: 'bg-white shadow-lg rounded-lg p-4 dark:bg-gray-800',
  child: WText('This is a card.', className: 'text-gray-800 dark:text-gray-100'),
);
```

## Constructor

```dart
WCard({
  Key? key,
  dynamic className = '',
  Color? color,
  Color? shadowColor,
  Color? surfaceTintColor,
  double? elevation,
  ShapeBorder? shape,
  bool borderOnForeground = true,
  EdgeInsetsGeometry? margin,
  Clip? clipBehavior,
  Widget? child,
  bool semanticContainer = true,
});
```

## Styling Examples

An elevated, padded card:

```dart
WCard(
  className: 'bg-white shadow-lg rounded-lg p-4 dark:bg-gray-800',
  child: WText('Elevated card', className: 'text-gray-800 dark:text-gray-100'),
);
```

A bordered, flat card:

```dart
WCard(
  className: 'bg-white border-2 border-gray-200 rounded-lg p-4 dark:bg-gray-900 dark:border-gray-700',
  child: WText('Flat bordered card', className: 'text-gray-700 dark:text-gray-200'),
);
```

## WCard vs WContainer

`WCard` is purpose-built for cards: it exposes `elevation`, `shadowColor`, and `surfaceTintColor`, which `WContainer` does not. `WContainer` is a general-purpose styled box. Reach for `WContainer` when you need a plain styled container, and `WCard` when you need a card surface with elevation and shadow.
