问题描述

你怎么称呼这些:

What do you call these:

body > p + p

在 CSS 选择器中?他们是:

in a CSS selector? Are they:

• 关系运算符
• 基于职位的标准
• 还有什么?

我只是不知道该怎么称呼他们.有正式名称吗?

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

(另外，abc、def和abc中有abc的正式名称吗??)

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

推荐答案

根据https://www.w3.org/TR/selectors-3/#combinators 它们被称为组合器".

According to https://www.w3.org/TR/selectors-3/#combinators they are called "combinators".

1. (空格字符)= 后代组合符
2. >(尖括号或大于号)= 子组合子
3. +(加号)= 相邻兄弟组合子
4. ~ (波浪号) = 通用兄弟组合子

1. (space character) = descendant combinator
2. > (angle bracket or greater-than sign) = child combinator
3. + (plus mark) = adjacent sibling combinator
4. ~ (tilde) = general sibling combinator
