我可以使用一个类名指定多个CSS类吗？

Question

我有几个css类,我想在一个元素上指定.但我不想每次都重复上3次,4次或更多次课程.

我想去

<span class ="class1 backgroundclass borderclass iconclass">Link</span>

至

<span class="linkClass">Link</span>

可以这样做吗？如果是这样,怎么样？

Answer 1

In normal CSS, you would have to include .linkClass into every class definition like this:

.class1, .linkClass { ...... }
.backgroundclass, .linkClass { ...... }
.borderclass, .linkClass { ...... }

Not very good for readability.

You could look into CSS pre-processors like LessCSS that make this easier. With LessCSS, it seems to be possible to do the following:

.linkClass {
  .class1;
  .backgroundclass;
  .borderclass;
}

然后LessCSS将编译最终的样式表.
