nth-child选择器写法

Question

.list{
  border-radius: 5px;
  padding: 10px;
  position: relative;
}
.list:nth-child(odd) {
  background-color: white;
  }

nth-child前面要不重复写.list，要怎么直接跟第一个css连起来

Answer 1

scss的写法是

.list{
  border-radius: 5px;
  padding: 10px;
  position: relative;

  &:nth-child(odd) {
  background-color: white;
  }
}
