CSS 3 中删除了“position”属性吗？
在最新版本中 CSS 属性 position 没有“自动完成”后，我联系了市长 IDE 的支持人员。他们说 CSS 3 中不存在。我做了一些挖掘，并回复了
“CSS Level 3 逐个模块地构建在 CSS Level 2 的基础上，使用 CSS2.1 规范为其核心。每个模块添加功能和/或 取代 CSS2.1 规范的一部分。” http://www.w3.org/TR/2011/注意-css-2010-20110512/#css3
此外，这定义了位置属性，尽管它不是 完成： http://www.w3.org/Style/CSS/specs#positioning
但他们坚持自己的立场。这是他们经过长时间辩论后的答复。
[..] CSS3中确实有很多属性是1:1复制的 CSS2.1。在 CSS3 引入的新属性中，您可以发现许多 CSS 2.1 CSS3草案中的定义。不幸的是，情况并非如此 位置和一些其他属性 [..]
我对他们没有怨恨，但很好奇。 CSS 3 中真的不存在 position 吗？
I contacted the support of a mayor IDE, after the CSS property position didn't "auto-complete" in the latest version. They said it doesn't exist in CSS 3. I did some digging, and replied
"CSS Level 3 builds on CSS Level 2 module by module, using the CSS2.1
specification as its core. Each module adds functionality and/or
replaces part of the CSS2.1 specification."
http://www.w3.org/TR/2011/NOTE-css-2010-20110512/#css3Additionally, this defines the position property, although it's not
finished: http://www.w3.org/Style/CSS/specs#positioning
But they stood their ground. This is a reply from them, after a length debate.
[..] there are indeed many properties in CSS3 which are copied 1:1 from
CSS2.1. Among new properties introduced in CSS3, you can find many CSS
2.1 definitions in CSS3 draft. Unfortunately, it's not the case with
position and some other properties [..]
I have no grudge towards them, but am curious. Does position really not exist in CSS 3?

虽然它可能不存在于新规范（待定）中，但它仍然有效。
我通过 CSS3 级别的验证器运行了这个，一切都很好
http://jigsaw。 w3.org/css-validator/#validate_by_input+with_options
While it may not exist in the new Spec (which is TBD), it remains valid.
I ran this through the validator at CSS3 level and it was all good

我不这么认为。请参阅 Chris Hanscom 编写的这份快速参考指南。您可以在第二页右侧栏的底部找到定位规范

I don't think so. Look at this Quick Reference Guide compiled by Chris Hanscom. You'll find the positioning spec at the bottom of the right hand column on the second page

虽然从去年开始，css3状态的快照就包含了
positionpoperty。如前所述，它与 css 2.1 中众所周知的位置相同。据我所知，css3 并没有“禁止”以前版本中引入的任何内容。http://www.w3.org/TR/css-2010/#properties（向下滚动到表格）
Although from last year, the snapshot of css3 state contains
positionpoperty. As stated before, it is the same well knowpositionthat in css 2.1. As far as I know css3 doesn't "forbid" anything introduced in previous versions.http://www.w3.org/TR/css-2010/#properties (scroll down to table)
