Vue项目中关于全局css的处理

// 关于声明全局的CSS：
	1 我们可以直接定义我们需要的。比如margin-top：10px
	2 我们可以引用第三方定义好的样式(element-ui或者elementPlus)


例如：
// 1.我们自己对margin的定义
$base-margin-5: 5px;
$base-margin-10: 10px;
$base-margin-15: 15px;
$base-margin-20: 20px;
$base-margin-20: 25px;


// 2. 引用第三方的CSS
$base-color-primary: var(--el-color-primary);
$base-color-primary-light1: var(--el-color-primary-light-1);
$base-border-color: var(--el-border-color);

//  比如：覆盖elementPlus的主题背景
@forward 'element-plus/theme-chalk/src/common/var.scss' with (
  $colors: (
    'primary': (
      'base': #990066,
    )
  )
);

@use "element-plus/theme-chalk/src/message.scss" as *;
@use "element-plus/theme-chalk/src/message-box.scss" as *;
