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

通过图片或首字母识别人或资源。

## 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 |
| --- | --- |
| `Avatar.color` | 原生颜色值或主题颜色键。 |
| `Avatar.radius` | 主题圆角键或原生圆角值。 |

## 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 }) {

return <M.Avatar color="blue" radius="xl">LU</M.Avatar>;
}
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



## Initials

To display initials instead of the default placeholder, set the `name` prop
to the name of the person, for example, `name="John Doe"`. If the name
is set, you can use `color="initials"` to generate a color based on the name:



## Allowed initials colors

By default, all colors from the default theme are allowed for initials. You can restrict them
by providing the `allowedInitialsColors` prop with an array of colors. Note that the default colors
array does not include custom colors defined in the theme – you need to provide them manually
if needed.



## Placeholder

If the image cannot be loaded or is not provided, `Avatar` will display a placeholder instead. By default,
the placeholder is an icon, but it can be changed to any React node:



## Variants



## Avatar.Group

The `Avatar.Group` component combines multiple avatars into a stack:



Note that you must not wrap child `Avatar` components with any additional elements,
but you can wrap `Avatar` with components that do not render any HTML elements
in the current tree, for example [Tooltip](/core/tooltip).

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

// Will not work correctly
function Demo() {
  return (
    <Avatar.Group spacing="sm">
      <div>
        <Avatar src="image.png" radius="xl" />
      </div>
      <Avatar src="image.png" radius="xl" />
      <Avatar src="image.png" radius="xl" />
      <Avatar radius="xl">+5</Avatar>
    </Avatar.Group>
  );
}
```

Example of usage with [Tooltip](/core/tooltip/):




Example of using `Avatar` as a link:



## Accessibility

Avatar renders an `<img />` HTML element. Set the `alt` prop to describe the image –
it is also used as the `title` attribute for the avatar placeholder when the image cannot be loaded.

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

function Demo() {
  // ❌ No alt for image
  return <Avatar src="./image.png" />;

  // ✅ alt is set
  return <Avatar src="./image.png" alt="Rob Johnson" />;

  // ✅ title is not required, but still recommended
  return <Avatar>RJ</Avatar>;

  // ✅ title is set on placeholder
  return <Avatar alt="Rob Johnson">RJ</Avatar>;
}
```


## 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。

  /** Width and height of the avatar, numbers are converted to rem @default 'md' */
  size?: MantineSize | (string & {}) | number;

  /** Key of `theme.radius` or any valid CSS value to set border-radius @default '1000px' */
  radius?: MantineRadius;

  /** Key of `theme.colors` or any valid CSS color @default 'gray' */

  name?: string;

  /** A list of colors that is used for autogenerated initials. By default, all default Mantine colors can be used except gray and dark. */
  allowedInitialsColors?: MantineColor[];
}

export type AvatarFactory = PolymorphicFactory<{

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

### 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: AvatarProps;
  defaultRef: HTMLDivElement;
  defaultComponent: 'div';
  stylesNames: AvatarStylesNames;
  vars: AvatarCssVariables;
  variant: AvatarVariant;
  staticComponents: {
    Group: typeof AvatarGroup;
  };
}>
MantineStyleProps
React.CSSProperties
MantineTheme
Partial<Record<Variable, string>>
Record<Variable, string>
Variable
MantineBreakpoint
Record<string, any>
StylesApiProps<AvatarFactory>
MantineSize
MantineRadius
MantineColor
MantineGradient
React.ComponentProps<'img'>
React.ReactNode
HTMLDivElement
```
