## 运行效果：  ## 第一步：复制代码到，`Home.vue`中 1. 打开`/views/Home.vue`，如果没有，请自行创建 2. 复制代码，到文件中，并运行看效果 代码如下： ``` <template> <div class="home"> <el-row> <el-col :span="24" class="panel-top"> <el-col :span="4"> <span class="p-l-20">后台管理系统</span> </el-col> <el-col :span="16" class="ofv-hd"> <div class="fl p-l-20 p-r-20 top-menu top-active">系统模块</div> </el-col> <el-col :span="4" class="pos-rel"> <el-dropdown @command="handleMenu" class="user-menu"> <span class="el-dropdown-link c-gra" style="cursor: default"> <span class="user-name">admin</span> <i class="el-icon-user-solid" aria-hidden="true"></i> </span> <el-dropdown-menu slot="dropdown"> <el-dropdown-item command="change_pwd">修改密码</el-dropdown-item> <el-dropdown-item command="logout">退出</el-dropdown-item> </el-dropdown-menu> </el-dropdown> </el-col> </el-col> </el-row> </div> </template> <script> export default { name: "Home", components: {}, methods: { handleMenu(val) { switch (val) { case 'logout': // 退出登录逻辑 break case 'change_pwd': // 修改密码逻辑 break } }, }, }; </script> <style scoped> .m-w-1280 { min-width: 1280px !important; } .panel { position: absolute; top: 0px; bottom: 0px; width: 100%; height: 100%; } .panel-top { height: 60px; line-height: 60px; background: #1f2d3d; color: #c0ccda; } .p-l-20 { padding-left: 20px !important; } .c-gra { color: #C0CCDA; } .user-menu { position: absolute!important; top: 0; right: 24px; } .user-name { margin-right: 6px; } .fl { float: left } .p-r-20 { padding-right: 20px !important; } .top-active { color: #44B5DF } .top-menu:hover { cursor: pointer; background: #324057; } .top-menu:active, .left-menu:active { color: #20a0ff; } </style> ``` ## 第二步：复制样式到App.vue ``` <style> body { background: #1f2d3d; font-family: Helvetica Neue, Helvetica, PingFang SC, Hiragino Sans GB, Microsoft YaHei, SimSun, sans-serif; font-weight: 400; -webkit-font-smoothing: antialiased; overflow: hidden; } body, html { height: 100%; width: 100%; margin: 0; padding: 0; } </style> ```
