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?)
