如何指定 CSS 样式表的媒体依赖项

The following are two ways to specify media dependencies for a stylesheet

  • Specify the target media from the stylesheet using @media or @import at -rules.
  • Specify the target media in the document language.

Example

Let’s look at an example of a @media rule -

<style>
   <!--
      @media print {
         body { font-size: 10pt }
      }

      @media screen {
         body { font-size: 12pt }
      }

      @media screen, print {
         body { line-height: 1.2 }
      }

   -->
</style>
