首先，我使用的是mpvue开发。样式使用的less，并且全局会定义一套主题。

@primary-color         : #ff8730;
@second-color          : #F48B4A;
@background-color      :#F3F3F3;
@second-text-color     :#787878;.flex-center-row {display: flex;flex-direction: row;justify-content: center;align-items: center;
}.flex-center-column {display: flex;flex-direction: column;justify-content: center;align-items: center;
}

<style lang="less">@import "../../theme/orange.less";page {background-color: @background-color;}
</style>

页面效果如下
