前提

我们使用的是Vab Admin Pro管理模板，它基于Vue2.x+element-ui。在线演示地址：https://chu1204505056.gitee.io/admin-pro/?hmsr=authorization&hmpl=&hmcu=&hmkw=&hmci=#/index

我还参考了element-ui的plain属性样式

代码

在public/static/css文件夹下新建公共样式 button.scss 文件

button.scss代码

::v-deep .hover-blue {
    color: #1890ff;
    background: #e8f4ff;
    border-color: #a3d3ff;
}

::v-deep .hover-blue:hover {

 在本页面引入button.scss样式

<style lang="scss" scoped>
@import 'public/static/css/button.scss';
::v-deep .el-divider--vertical {
  height: auto;

</style>
