} 通用性分析：
✅ 可以直接使用的部分：
- CSS变量定义：断点变量（--breakpoint-xs、--breakpoint-sm 等）
- 基础网格系统：.container、.row、.col 等
- 响应式工具类：显示/隐藏、文本对齐、间距、字体大小等
- 基础响应式组件：表格、图片、按钮组、表单等
⚠️ 需要项目适配的部分：
- UI框架特定样式：
/* 这些是针对Element UI的，如果项目使用其他UI框架需要修改 */.datepicker-responsive .el-date-editor.cascader-responsive .el-cascader.tabs-responsive .el-tabs__nav颜色和主题
/* 这些颜色值可能需要匹配项目主题 */.focus-visible { outline: 2px solid #007bff; }.scrollbar-responsive::-webkit-scrollbar-thumb { background: #888; }建议使用方式：
- 作为基础模板：复制到新项目，然后根据需求调整
- 按需引入：只复制需要的部分，避免冗余
- 项目定制：根据具体项目的设计规范和UI框架进行适配
总的来说，这是一个很好的响应式设计起点，但建议根据具体项目需求进行适当修改和优化。
