+## 核心功能实现 💡
+
+### 文件上传处理
+```javascript
+const handleFileUpload = () => {
+  const input = document.createElement('input')
+  input.type = 'file'
+  input.accept = activeTab === 'video' ? 'video/*' : 'image/*'
+  input.multiple = activeTab === 'image'
+  
+  input.onchange = (e) => {
+    const files = Array.from(e.target.files)
+    if (files.length > 0 && validateFiles(files)) {
+      simulateUpload(files)
+    }
+  }
+  
+  input.click()
+}
+```
+
+### 拖拽上传实现
+```javascript
+const handleDrop = (e) => {
+  e.preventDefault()
+  e.stopPropagation()
+  setIsDragOver(false)
+  
+  const files = Array.from(e.dataTransfer.files)
+  if (files.length > 0 && validateFiles(files)) {
+    simulateUpload(files)
+  }
+}
+```
+
+### 文件验证机制
+```javascript
+const validateFiles = (files) => {
+  const validImageTypes = ['image/jpeg', 'image/jpg', 'image/png', 'image/webp']
+  const validVideoTypes = ['video/mp4', 'video/mov', 'video/avi']
+  
+  const validTypes = activeTab === 'video' ? validVideoTypes : validImageTypes
+  const maxSize = activeTab === 'video' ? 2 * 1024 * 1024 * 1024 : 32 * 1024 * 1024
+  
+  return files.every(file => 
+    validTypes.includes(file.type) && file.size <= maxSize
+  )
+}
+```
+
+## 样式特色 🎨
+
+### 响应式设计
+- 桌面端：固定侧边栏布局
+- 移动端：隐藏侧边栏，堆叠布局
+- 自适应文件网格：根据屏幕大小调整列数
+
+### 动画效果
+- 拖拽时的放大效果
+- 进度条的流光动画
+- 文件项的悬停过渡
+- 页面切换的淡入效果
+
+### 色彩方案
+- 主色调：#ff4757（小红书红）
+- 背景色：#f5f7fa（浅灰蓝）
+- 文字色：#333（深灰）
+- 边框色：#e8eaed（浅灰）
+
+## 待扩展功能 🔮
+
+- **后端集成**：连接真实的文件上传 API
+- **用户认证**：登录注册功能
+- **内容编辑**：笔记内容编辑器
+- **数据统计**：真实的数据看板功能
+- **社交功能**：评论、点赞等互动功能
+
+## 开发说明 📝
+
+这个项目完全基于前端实现，所有的上传功能都是模拟的。文件预览使用了 `URL.createObjectURL()` 来生成本地预览链接。在实际部署时，需要：
+
+1. 集成后端文件上传 API
+2. 实现用户认证系统
+3. 添加数据持久化
+4. 优化性能和安全性
+
+## 浏览器兼容性 🌐
+
+- Chrome 90+
+- Firefox 88+
+- Safari 14+
+- Edge 90+
