推荐答案
级联在这个上下文中意味着，因为多个样式表规则可以应用于特定的的HTML，必须有一种已知的方法来确定哪个特定的样式表规则适用于哪一段HTML。
"Cascading" in this context means that because more than one stylesheet rule could apply to a particular piece of HTML, there has to be a known way of determining which specific stylesheet rule applies to which piece of HTML.
使用的规则是通过从较一般的规则级联到所需的特定规则来选择的。选择最具体的规则。
The rule used is chosen by cascading down from the more general rules to the specific rule required. The most specific rule is chosen.
