Question

我正在尝试使用纯CSS来更改悬停时类的宽度。

到目前为止，过渡工作是在更改类方面进行的，但是类.b和.c不会影响到它们之前的类的宽度。将鼠标悬停在.b

上时，我需要上一个类（即.a类）进行收缩

我在下面发布了代码，希望有人提供理想情况下仅包含CSS的解决方案。

.box {
  width: 100px;
  height: 100px;
  border: 1px solid red;
  transition: width 0.2s ease-out;

}

.box:hover {
  width: 200px
}

Answer 2

您可以使用flexbox来执行此操作。您只需更改当前悬停的元素的宽度，它的兄弟姐妹就会适应它。

相反呢？ https://jsfiddle.net/jtnxL7cz/

.column {
  float: left;
  width: 33.33%;
  height:100%;
  transition: 0.3s;
}

.row:hover .column {
  width: 30%;
}

.row:hover .column:hover {
  width: 40%;
}

.a{
  background-color: #ff0000;
}

.b{
  background-color: #eeeeee;
}

.b:hover{
  background-color: #c41333;
}

.c{
  background-color: #cccccc;
}

.c:hover{
  background-color: #c41333;
}
