在MDN中::: before/:: after + flexbox [英] ::before/::after + flexbox in MDN

问题描述

我在 MDN CSS 主页上看到以下新闻:

I see the following news item on MDN CSS homepage:

Gecko对柔性盒的支持已进行了调整，以匹配最近的规范说明:从Firefox 23开始，::before和::after将是flex项目，因此可以使用order和align-self重新定位.
(2013年5月3日)

Gecko's support of flexible boxes has been adapted to match a recent specification clarification: from Firefox 23 ::before and ::after will be flex items, and as such can be repositioned using order and align-self.
(May 3rd, 2013)

它指的是什么规格?
我在 CSS灵活框布局模块中找不到对::before/::after的任何引用.

What specification does it refer to?
I cannot find any references to ::before/::after in CSS Flexible Box Layout Module.

推荐答案

这是在 bug 867454 .正如评论#0所言，不执行它是一个错误.

This was implemented in bug 867454. Not implementing it was a mistake, as comment #0 tells.

规范说:

flex容器的内容由零个或多个flex项组成:flex容器的每个流入子元素都将成为一个flex项，而直接包含在flex容器中的每个连续文本都被包裹在一个匿名中弹性项目.

The contents of a flex container consists of zero or more flex items: each in-flow child of a flex container becomes a flex item, and each contiguous run of text that is directly contained inside a flex container is wrapped in an anonymous flex item.

而且确实包含::before/::after伪元素(至少现在，mozilla人士以这种方式解释它，我同意).

And that does include ::before/::after pseudo elements (at least the mozilla folks interpret it this way now, and I'd concur).

针对开发人员的Firefox 23" 也提供了此信息，明确引用了到::before和::after作为流入".

"Firefox 23 for developers" also features this information, explicitly referring to ::before and ::after as "in-flow".

流中:: after和:: before伪元素现在是flex项目(错误867454).

In-flow ::after and ::before pseudo-elements are now flex items (bug 867454).
