+## 前端开发规范
+
+### UI 组件使用原则
+**重要**: 在开发前端页面时,必须优先使用 UI 框架的组件。
+
+- **优先使用 antd-mobile 组件**: 项目使用 antd-mobile 作为 UI 框架,开发时应优先查找并使用框架提供的组件
+- **常用组件示例**:
+  - 表单输入: 使用 `Input` 组件,而非原生 `<input>`
+  - 按钮: 使用 `Button` 组件,而非原生 `<button>`
+  - 表单: 使用 `Form` 和 `Form.Item` 组件
+  - 提示信息: 使用 `Toast` 组件,而非自定义提示框
+  - 对话框: 使用 `Dialog` 组件
+  - 列表: 使用 `List` 组件
+- **仅在必要时自定义**: 只有当 antd-mobile 没有提供对应组件时,才使用自定义组件
+- **样式处理**: 使用 CSS Modules (`.module.less`) 编写组件样式,避免全局样式污染
+
+### 前端项目结构
+- **web/src/pages/** - 页面组件
+- **web/src/components/** - 可复用组件
+- **web/src/pages/*.module.less** - 页面样式文件 (CSS Modules)
