scss 格式：缩进和 NestingDepth

Question

我的 ionic 3 项目中有一个 scss 文件，当我运行这个命令时：npm 运行 scss-lint 来测试 scss 语法我在我的 cmd 中收到了这些警告：

这是我粘贴在 pastbin 中的 scss 文件 https://pastebin.com/1ZqC2Ptc

能否请您提供一些 link 帮助我格式化 scss 文件，或者是否有任何插件可以在可视化代码编辑器上配置，我尝试了很多时间来解决缩进问题和嵌套深度..?

Answer 1

错误NestingDepth: Nesting should be no greater than 1不是指大括号嵌套，它指的是选择器嵌套。

请记住，SASS 中的大括号嵌套只是帮助提高源代码可读性的糖分。

例如，

div {
    a {
      font-size: 15px;
    }
}

只是 SASS

的糖

div a {
    font-size: 15px;
}

这意味着，以你的例子为例：

page-profile {
   .profileinformations> h1 > ion-icon {
     font-size: 15px;
     color: color($colors, icon-color);
   }
}

嵌套深度为 4：page-profile .profileinformations > h1 > ion-icon。
