CSS“选择器”之间的东西是什么，称为？ [英] What is that thing between CSS "selectors" called?

问题描述

：

p + p

是：

• 关系运算符


• 基于位置的条件


• 还有什么吗？

我不知道该叫什么。是否有官方名称？

（以及 abc 在 abc ？中的 abc，def 和 a $ b

解决方案

根据 http://www.w3.org/TR/CSS2/selector.html#selector-syntax ，它们被称为组合器。

感谢Duncan Babbage指出有（或只有）其中三个：

1. 空格字符=后裔


2. > =子


3. + plus mark = adjacent following（next）sibling


4. 而CSS3添加了一个符号〜 =一般关系同级

What do you call these:

body > p + p

in a CSS selector? Are they:

• Relational operators
• Position-based criteria
• Something else?

I just have no idea what to call them. Is there an official name?

(And, also, are there official names for a b c in a b c, d e f and a in a b c?)

解决方案

According to http://www.w3.org/TR/CSS2/selector.html#selector-syntax they are called "combinators".

Thanks to Duncan Babbage for pointing out there are (or were) only three of them:

1. space character = descendant
2. > = child
3. + plus mark = adjacent following (next) sibling
4. And CSS3 adds a tilde ~ = general following sibling
