我不知道我是否以错误的方式使用了运算符,但是如果你看看它的&样式slider__slide和内部。&--active为什么不&--active继承 中定义的所有其他样式slider__slide?
您可以在此处查看代码笔
因为有两个不同的类.slider__slide和.slider__slide--active。在这种情况下你必须继承父类
.slider__slide {
background: blue;
position: absolute;
height: 100%;
width: 100%;
opacity: 0;
&--active {
@extend .slider__slide;
opacity: 1;
}
}

或者另一种方式,您必须使用两个类来修改元素:
<div class="slider__slide slider__slide--active"
