+# UI and Functional Improvements Spec
+
+## Why
+User reported several UI inconsistencies, visual bugs, and missing feedback mechanisms that affect the usability and aesthetic quality of the application. Specifically, the announcement feature needs polish, font colors need adjustment for dark mode, and feedback for save operations is missing.
+
+## What Changes
+
+### Announcement Feature
+- **Settings Dialog (`AnnouncementSettingsDialog.vue`)**:
+  - Fix Markdown toolbar layout to prevent conflicts/overflow (use `flex-wrap`).
+  - Fix Preview functionality (ensure `parseMarkdown` works).
+  - Add "Save Success" feedback when adding/modifying announcements.
+- **Widget (`AnnouncementWidget.vue`)**:
+  - **Hide the widget completely** when there are no active/upcoming announcements (User requirement: "only shows when there are announcements").
+  - Make the widget clickable to open a detail popup of the current announcement.
+- **Detail Popup (`AnnouncementOverlay.vue` or new)**:
+  - Ensure manually clicking the widget opens the detail view.
+
+### Homework UI
+- **Homework Grid (`HomeworkGrid.vue`)**:
+  - Change "Self Correction" (自批) tag color from Orange/Warning to **Green/Success**.
+- **Homework Edit Dialog (`HomeworkEditDialog.vue`)**:
+  - **Add Item Button**: Change style to be more obvious (White background, black text).
+  - **Metadata Buttons** (Submission Time, Self Correction): Adjust height and border-radius to match the "Preset" chips on the left for visual consistency.
+
+### General UI
+- **Font Colors**:
+  - Change gray text to **White** in key locations (e.g., Homework Edit dialog controls, Announcement widget text) for better contrast in dark mode.
+- **Floating Toolbar**:
+  - Fix the "Refresh" button loading state (it appears stuck).
+- **Feedback**:
+  - Implement a "Save Success" (green) notification (Snackbar/Toast) that triggers after successful save operations (Homework save, Announcement save, etc.).
+
+## Impact
+- **Affected Components**: `AnnouncementSettingsDialog`, `AnnouncementWidget`, `HomeworkGrid`, `HomeworkEditDialog`, `FloatingToolbar`, `index.vue`.
+- **User Experience**: Improved visual consistency, better feedback on actions, and cleaner interface when no announcements are present.
+
+## ADDED Requirements
+### Requirement: Save Feedback
+The system SHALL display a green "Save Success" notification (Snackbar) when:
+- A homework entry is saved (auto-save or manual).
+- An announcement is added or modified.
+- Attendance is saved.
+
+### Requirement: Announcement Widget Behavior
+- **WHEN** there are no active announcements, **THEN** the widget on the main board SHALL be hidden.
+- **WHEN** the widget is visible and clicked, **THEN** it SHALL open the announcement detail popup.
+
+## MODIFIED Requirements
+### Requirement: Visual Styles
+- **Self Correction Tag**: SHALL be Green.
+- **Add Item Button**: SHALL be White (filled).
+- **Metadata Buttons**: SHALL match Preset Chips in size and shape.
+- **Refresh Button**: SHALL NOT show loading state indefinitely.

+# Tasks
+
+- [x] Task 1: Update Announcement System
+  - [x] SubTask 1.1: Fix `AnnouncementSettingsDialog.vue`:
+    - Fix Markdown toolbar layout (flex-wrap).
+    - Ensure Preview works (check `parseMarkdown` usage).
+    - Add "Save Success" notification trigger on save.
+  - [x] SubTask 1.2: Update `AnnouncementWidget.vue`:
+    - Add logic to hide component if `notifications` is empty.
+    - Add click handler to open detail popup (emit event or call method).
+  - [x] SubTask 1.3: Update `index.vue` to handle widget click and show detail popup.
+
+- [x] Task 2: Update Homework UI
+  - [x] SubTask 2.1: Update `HomeworkGrid.vue`:
+    - Change "Self Correction" chip color to `success`.
+  - [x] SubTask 2.2: Update `HomeworkEditDialog.vue`:
+    - Style "Add Item" button (color="white", variant="flat").
+    - Style "Submission Time" and "Self Correction" buttons to match `v-chip` style (height, rounded).
+    - Ensure text colors are white where appropriate.
+
+- [x] Task 3: Fix General UI & Feedback
+  - [x] SubTask 3.1: Fix `FloatingToolbar.vue` refresh button loading state (debug `loading` prop).
+  - [x] SubTask 3.2: Implement Global "Save Success" Snackbar in `index.vue` and expose method/event to trigger it from child components.
+  - [x] SubTask 3.3: specific font color adjustments (Grey to White) in `AttendanceSidebar` and `HomeworkGrid` as requested.
+
+# Task Dependencies
+- Task 3.2 (Global Snackbar) should be done before Task 1.1 and 1.3 to ensure feedback works.

+# ClassHomeworkBoard - Docker 部署版本
+
+这是一个专门为服务器部署设计的 Node.js 后端程序，它包含了 Express 服务器和构建好的前端静态文件。此版本去除了对 Windows 特有功能（如通过 `user32.dll` 抓取 PPT 和 WPS 窗口）的依赖，完美适配 Linux 和 Docker 环境。
+
+## 包含内容
+
+- `server.js`: 提供 `/api/local-file/*` 本地存储接口的 Express 后端。
+- `dist/`: 已经构建好的前端静态资源文件。
+- `Dockerfile`: 用于构建 Docker 镜像的配置文件。
+- `package.json`: 服务器的 npm 依赖配置文件。
+
+## 如何使用 Docker 部署
+
+1. **构建 Docker 镜像**
+   在 `docker-server` 目录下运行以下命令：
+   ```bash
+   docker build -t classhomeworkboard .
+   ```
+
+2. **运行 Docker 容器**
+   ```bash
+   docker run -d -p 3001:3001 -v chwb_data:/app/data --name chwb classhomeworkboard
+   ```
+   > 这里的 `-v chwb_data:/app/data` 表示将容器内的 `/app/data`（存储 JSON 数据的文件夹）挂载到外部卷，防止数据随容器销毁而丢失。
+
+3. **访问服务**
+   打开浏览器，访问 `http://<服务器IP>:3001` 即可使用。
+
+## 如果你需要更新前端代码
+
+如果你在主项目中修改了 Vue 前端代码：
+1. 在项目根目录运行 `npm run build`（或 `pnpm run build`）重新打包前端。
+2. 将打包后生成的 `dist` 文件夹覆盖到本目录的 `dist` 文件夹。
+3. 重新执行 Docker 镜像的构建与部署步骤。
+
+## 本地（不使用 Docker）直接运行
+
+如果你想直接在服务器的 Node 环境中运行：
+```bash
+npm install
+npm start
+```
+默认会在 3001 端口启动。
