- 通用选择器 | Universal selectors (Selectors) - CSS 中文开发手册
CSS 通用选择器（*）匹配任何类型的元素。
* { color: green; } - 从CSS3开始，星号可以与namespaces结合使用：
ns|*- 匹配命名空间ns中的所有元素 *|* - 匹配所有元素|*-匹配所有没有声明命名空间的元素
语法
* { style properties }
星号对于简单的选择器是可选的。例如，*.warning和.warning是等价的。
实例
* [lang^=en] { color: green; } *.warning { color: red; } *#maincontent { border: 1px solid blue; } .floating { float: left } /* automatically clear the next sibling after a floating element */ .floating + * { clear: left; } - <p class="warning"> <span lang="en-us">A green span</span> in a red paragraph.</span> </p> <p id="maincontent" lang="en-gb"> <span class="warning">A red span</span> in a green paragraph.</span> </p>
