CSS类可以继承一个或多个其他类吗？

问题：

I feel dumb for having been a web programmer for so long and not knowing the answer to this question, I actually hope it's possible and I just didn't know about rather than what I think is the answer (which is that it's not possible). 我作为一个网络程序员已经这么长时间了，而且不知道这个问题的答案，这让我感到很愚蠢。我实际上希望这是可能的，我只是不知道答案，而不是我认为答案是什么（那是不可能的） 。

My question is whether it is possible to make a CSS class that "inherits" from another CSS class (or more than one). 我的问题是，是否有可能使一个CSS类从另一个CSS类（或多个CSS类）“继承”。

For example, say we had: 例如，假设我们有：

.something { display:inline }
.else      { background:red }

What I'd like to do is something like this: 我想做的是这样的：

.composite 
{
   .something;
   .else
}

where the ".composite" class would both display inline and have a red background 其中“ .composite”类将同时显示内联并具有红色背景
