如何“大于”或“>”。字符在CSS中使用？ [英] How is the "greater than" or ">" character used in CSS?

问题描述

我在CSS文件中看到过这个字符多次，但我不知道它的用法。

I have seen this character a number of times in CSS files but I have no idea how its used. Can anyone explain it to me and show how they are useful in making a page style easier?

推荐答案

这是一个CSS子选择器。 P> SPAN 表示将所有符合 P 标签的子标签的样式应用于所有SPAN标签。

It's a CSS child selector. P > SPAN means applying the style that follows to all SPAN tags that are children of a P tag.

请注意，儿童是指直系后裔，而不是任何后代。 P SPAN 是一个后代选择器，将后面的样式应用于所有 SPAN 是 P 标记的子项，或者是 P 标记的子项/后代的任何其他标记的递归子项。 P> SPAN 仅适用于 P 标签的子标签 SPAN 。

Note that "child" means "immediate descendant", not just any descendant. P SPAN is a descendant selector, applying the style that follows to all SPAN tags that are children of a P tag or recursively children of any other tag that is a child/descendant of a P tag. P > SPAN only applies to SPAN tags that are children of a P tag.
