    脚本 | @media.scripting (Media Queries) - CSS 中文开发手册

    该scripting CSS @media媒体功能可基于脚本(如JavaScript)是否可用来应用样式。

    语法

    该scripting功能被指定为从下面的列表中选择的关键字值。

    none脚本在当前文档中完全不可用。

    initial-only在初始页面加载期间启用脚本,但不是之后。

    enabled当前文档支持并激活脚本。

    例子

    HTML

    You do not have scripting available. :-(

    Your scripting is only enabled during the initial page load. Weird.

    You have scripting enabled! :-)

    CSS

    p {
      color: lightgray;
    }
    
    @media (scripting: none) {
    ? .script-none {
    ?    color: red;
      }
    }
    
    @media (scripting: initial-only) {
    ? .script-initial-only {
    ?   color: red;
      }
    }
    
    @media (scripting: enabled) {
    ? .script-enabled {
    ?   color: red;
      }
    }
