ruoyi框架修改左侧菜单样式

菜单效果

ruoyi前端框架左侧的菜单很丑，我们需要修改一下样式，下面直接看效果。

修改代码

1、sidebar.scss

.el-menu-item, .el-submenu__title {overflow: hidden !important;text-overflow: ellipsis !important;white-space: nowrap !important;// 每个菜单增加下边框，新增border-bottom: 1px solid #3c4f66;}// menu hover.submenu-title-noDropdown,.el-submenu__title {&:hover {// background-color: rgba(0, 0, 0, 0.06) !important;// 菜单从左网友颜色渐变，新增background: linear-gradient(270deg, rgb(31, 45, 61), rgb(66 105 149)) !important;border-left: 3px solid rgb(145, 196, 247);}}

2、Navbar.vue

因为navbar这个文件，好多页面都引用了，所以在这个页面写的样式会全局通用。

 li.el-menu-item.is-active{background: linear-gradient(270deg, rgb(31, 45, 61), rgb(66 105 149)) !important;border-left: 3px solid rgb(145, 196, 247);font-size: 16px;}li.el-menu-item:hover{background: linear-gradient(270deg, rgb(31, 45, 61), rgb(66 105 149)) !important;border-left: 3px solid rgb(145, 196, 247);font-size: 16px;}.submenu-title-noDropdown:first-child{border-top: 1px solid #3c4f66;}.el-submenu .el-menu-item {padding: 0 20px 0 0px;}#app .sidebar-container .svg-icon{margin-right: 6px;}.el-submenu__title{padding-left: 10px !important;}.el-menu-item{padding-left: 28px !important;}.submenu-title-noDropdown{padding-left: 10px !important;}

 3、修改结束

经过上面的代码，就可以有左侧菜单的效果。
