How do i get the version of CSS that I am using?
推荐答案
虽然CSS规范定义在几个版本（v2，2.1，3），CSS版本并不真正与开发人员相关;您需要更关心哪些网络浏览器支持给定的功能。
Although the CSS specification is defined in several versions (v2, 2.1, 3), the CSS version isn't really relevant to the developer; you need to be more concerned with which web browsers support a given feature.
有用的是知道给定的功能在CSS2,2.1或3中定义，因为它可以给你一个想法的功能是多么老，因此浏览器将支持它的可能性 - 例如 border-radius 是一个CSS3功能，所以浏览器更多
It is useful to know that a given feature was defined in CSS2, 2.1 or 3 because that can give you an idea of how old the feature is, and therefore how likely it is that browsers will support it -- for example border-radius is a CSS3 feature, so browsers more than a couple of years old may not support it fully.
您可以从以下网站中了解哪些浏览器支持哪些CSS功能：
You can find out what CSS features are supported in which browsers from the following sites:
