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。
