inherit

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，通常只在覆盖原有的值的时候使用。

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; }
