Mantine Core 的独立组件，请不要替换为 JGuang UI/Base UI 的同名 API。

## 安装

```bash
npm install @mantine/core@9.7.1 @mantine/hooks@9.7.1
```

入口引入 `@mantine/core/styles.css`，并在根组件使用 `MantineProvider`；通过 `forceColorScheme` 同步深浅色主题。

## 使用与验证

在左侧选择组件，在预览中操作它的状态；使用“查看代码”检查真实源码。安装后执行类型检查和构建，再验证键盘焦点、手机布局与深浅色主题。

## 版本与兼容性

固定的 Mantine Core 9.7.1 要求 React 和 React DOM 满足 `^19.2.0`，并配套 `@mantine/hooks@9.7.1`。此条件来自实际 npm 包的 peerDependencies。React 18 或其他不兼容版本不能强行安装；先向项目负责人说明升级影响并确认方案，不使用 --force/--legacy-peer-deps 掩盖冲突。入口的原生 Provider 开启 `theme.respectReducedMotion`，并用 `forceColorScheme` 控制深浅色。

## 适用场景

组合相关信息和操作。

## 本地示例使用的原生参数

以下参数由本地、经过类型检查的 JSX 示例提取，按所属组件区分。不是全部属性清单；完整签名和继承关系见下方固定源码参考。

| 组件参数 | 说明 |
| --- | --- |
| `Card.withBorder` | 展示原生边框。 |
| `Card.shadow` | 主题阴影键或原生阴影值。 |
| `Card.radius` | 主题圆角键或原生圆角值。 |
| `Text.fw` | Mantine 字重样式参数。 |
| `Button.mt` | Mantine 顶部外边距样式参数。 |

## 交互与状态检查

当前场景：默认。切换支持的禁用、错误或只读场景后检查真实行为；无此原生状态的组件不会被强行添加统一属性。验证键盘焦点和退出方式，修改值后按原生回调签名连接业务状态。

## 业务接入边界

示例内容和状态仅保存在本地，不提供服务端持久化、授权或数据请求。静态展示组件不应被当作已完成的业务流程。

## 宿主配置

先安装固定版本 @mantine/core 和 @mantine/hooks，在入口引入 @mantine/core/styles.css，并使用 MantineProvider。示例的 theme 和 variant 是 JGuang 编写的宿主参数，不是所有原生组件都接受的统一 API；通过 forceColorScheme 同步应用主题。源码面板中的原生实现仅供阅读，使用 npm 导出，不要单独复制内部实现。此批只覆盖 Core，不包括日期、图表和表单扩展包。上游详细说明保留英文，不宣称全文中文化。


## 可运行用法

以下代码使用资源原生 API；不是把其他设计系统的同名组件替换进来。

```tsx
import { useState } from 'react';
import * as M from '@mantine/core';
import '@mantine/core/styles.css';


function ComponentPreview({ variant = 'Default' }: { variant?: string }) {
const content = <M.Text>Build something beautiful / 构建美好的界面</M.Text>;
return <M.Card withBorder shadow="sm" radius="md"><M.Text fw={600}>A complete foundation</M.Text>{content}<M.Button mt="md">Get started</M.Button></M.Card>;
}
export default function Example({ variant = 'Default', theme = 'light' }: { variant?: string; theme?: 'light' | 'dark' }) {
return <M.MantineProvider forceColorScheme={theme} theme={{ respectReducedMotion: true }}><ComponentPreview variant={variant} /></M.MantineProvider>;
}

```


## 可用状态与示例

默认

示例遵循 Mantine 原生 API。支持多状态的输入组件可将示例中的 variant 改为 Disabled、Invalid 或 Read only；这些只是示例标签，不是新增的组件属性。改造时保留组件要求的数据、受控值、store 和复合子组件结构。


## Usage

`Card` is a wrapper around the [Paper](/core/paper/) component with some additional styles and a `Card.Section`
component that allows you to split the card into sections. If you do not need sections, you can use the [Paper](/core/paper/) component instead.



## Horizontal orientation



## Polymorphic component

Card is a [polymorphic component](/guides/polymorphic/), you can change its root element:



## Card.Section

`Card.Section` is a special component that is used to remove Card padding from its children while other elements still have horizontal spacing.
`Card.Section` works in the following way:

- If the component is the first child in Card, then it has negative top, left and right margins
- If it is the last child in Card, then it has negative bottom, left and right margins
- If it is in the middle, then only the left and right margins will be negative

```tsx
import { Card, Text } from '@mantine/core';

function Demo() {
  return (
    <Card padding="xl">
      {/* top, right, left margins are negative – -1 * theme.spacing.xl */}
      <Card.Section>First section</Card.Section>

      {/* Content that is not inside Card.Section will have theme.spacing.xl spacing on all sides relative to Card */}
      <Text>Some other content</Text>

      {/* right, left margins are negative – -1 * theme.spacing.xl */}
      <Card.Section>Middle section</Card.Section>

      {/* bottom, right, left margins are negative – -1 * theme.spacing.xl */}
      <Card.Section>Last section</Card.Section>
    </Card>
  );
}
```

Note that `Card` relies on mapping direct children and you cannot use fragments or other wrappers for `Card.Section`:

```tsx
import { Card } from '@mantine/core';

function Demo() {
  return (
    <Card padding="xl">
      <div>
        <Card.Section>Won't work</Card.Section>
      </div>

      <>
        <Card.Section>Won't work either</Card.Section>
      </>

      <Card.Section>Works fine</Card.Section>
    </Card>
  );
}
```

## Polymorphic Card.Section

`Card.Section` is a [polymorphic component](/guides/polymorphic/), you can change its root element:



## withBorder and inheritPadding props

- `withBorder` prop adds top and bottom borders to `Card.Section` depending on its position relative to other content and sections
- `inheritPadding` prop adds the same left and right padding to `Card.Section` as set in the `Card` component




## 源码参数参考

以下实现签名和类型从本地固定版本源码生成。保留可选属性、原生继承类型、联合分支和 never 限制；不会将其他设计系统的 API 混入。forwardRef 实现中的 ref 属于 React 引用，不是新增业务属性。此区域是原始类型参考，不是上游说明的全文翻译。


```ts
Card(_props)
```



```ts
export type CardStylesNames = 'root' | 'section';

export type CardCssVariables = {
  root: '--card-padding';
};

export interface CardProps extends BoxProps, StylesApiProps<CardFactory> {
  /** Key of `theme.shadows` or any valid CSS value to set `box-shadow` */
  shadow?: MantineShadow;

  /** Key of `theme.radius` or any valid CSS value to set border-radius, numbers are converted to rem @default theme.defaultRadius */
  radius?: MantineRadius;

  /** Adds border to the card */
  withBorder?: boolean;

  /** Key of `theme.spacing` or any valid CSS value to set padding @default 'md' */
  padding?: MantineSpacing;

  /** Card content */
  children?: React.ReactNode;

  /** Card orientation @default 'vertical' */
  orientation?: 'horizontal' | 'vertical';
}

export type CardFactory = PolymorphicFactory<{
  props: CardProps;
  defaultRef: HTMLDivElement;
  defaultComponent: 'div';
  stylesNames: CardStylesNames;
  vars: CardCssVariables;
  staticComponents: {
    Section: typeof CardSection;
  };
}>;

export type Mod = Record<string, any> | string;

export type BoxMod = Mod | Mod[] | BoxMod[];

export interface BoxProps extends MantineStyleProps {
  /** Class added to the root element, if applicable */
  className?: string | undefined;

  /** Inline style added to root component element, can subscribe to theme defined on MantineProvider */
  style?: MantineStyleProp;

  /** CSS variables defined on root component element */
  __vars?: CssVarsProp;

  /** `size` property passed down the HTML element */
  __size?: string;

  /** Breakpoint above which the component is hidden with `display: none` */
  hiddenFrom?: MantineBreakpoint;

  /** Breakpoint below which the component is hidden with `display: none` */
  visibleFrom?: MantineBreakpoint;

  /** Determines whether component should be hidden in light color scheme with `display: none` */
  lightHidden?: boolean;

  /** Determines whether component should be hidden in dark color scheme with `display: none` */
  darkHidden?: boolean;

  /** Element modifiers transformed into `data-` attributes, for example, `{ 'data-size': 'xl' }`, falsy values are removed */
  mod?: BoxMod;
}

export interface CSSProperties extends React.CSSProperties {
  [key: string]: any;
}

type MantineStyle = CSSProperties | ((theme: MantineTheme) => CSSProperties);

export type MantineStyleProp = MantineStyle | MantineStyle[] | MantineStyleProp[] | undefined;

export type CssVariable = `--${string}`;

export type CssVariables<Variable extends string = CssVariable> = Partial<Record<Variable, string>>;

export type CssVars<Variable extends string = CssVariable> =
  | CssVariables<Variable>
  | ((theme: MantineTheme) => CssVariables<Variable>)
  | CssVars<Variable>[];

export type CssVarsProp<Variable extends string = CssVariable> =
  | CssVars<Variable>
  | CssVars<Variable>[];
```


### 原生与外部类型

以下外部类型仍由 React 或资源自身依赖定义，没有手工展开为虚构属性。实际可用类型以安装版本的 TypeScript 检查为准。


```ts
PolymorphicFactory<{
  props: CardProps;
  defaultRef: HTMLDivElement;
  defaultComponent: 'div';
  stylesNames: CardStylesNames;
  vars: CardCssVariables;
  staticComponents: {
    Section: typeof CardSection;
  };
}>
MantineStyleProps
React.CSSProperties
MantineTheme
Partial<Record<Variable, string>>
Record<Variable, string>
Variable
MantineBreakpoint
Record<string, any>
StylesApiProps<CardFactory>
MantineShadow
MantineRadius
MantineSpacing
React.ReactNode
HTMLDivElement
```
