我们可以在另一个css声明中导入额外的css文件。@import规则用于此目的,它在文档中链接样式表。通常在一个样式表依赖于另一个样式表时使用。它在<head>标签内的@charset声明之后的文档顶部指定。

@import规则的语法如下:
@import /*url or list-of-media-queries*/
The media queries can be compound statements which may specify the behavior of the document in different media.
Example
The following examples implement the @import rule −
