inherit - CSS（层叠样式表） 编辑

 inherit 关键字使得元素获取其父元素的计算值。它可以应用于任何CSS属性，包括CSS简写 all。

对于继承属性，inherit 关键字只是增强了属性的默认行为，只有在重载(overload)其它规则的时候被使用。对于非继承属性，inherit 这指定的行为通常没有多大意义，一般使用使用 initial 或 unset 作为替代。

继承始终来自文档树中的父元素，即使父元素不是包含块。

示例

/* 设置二级标题的颜色为绿色 */
h2 { color: green; }

/* ...but leave those in the sidebar alone so they use their parent's color */
#sidebar h2 { color: inherit; }

在下面这个例子中，如果sidebar 中h2元素的div匹配下面的规则的话，颜色会变成蓝色。

div#current { color: blue; }
