控制宽度变换( CSS )

Question

我在div中有一些卡片，希望它们在悬停时改变宽度，但是有两个问题：

1. 我想使用转换，但是那些没有悬停的卡会在悬浮卡结束后进行转换。我想这么做，simultaneously.

1. 如何更改第3和第4张卡的来源，从而使其宽度从右向左变化？

这是我的密码

问题是网格显示和错误的css选择器(.card:hover~ :not(:hover))。另外，在选择器中不要使用转换:悬停选择器。

​

body {
  background-color: #333;
  height: 100vh;
  display: flex;
  align-items: center;
  justify-content: center;
}

.cardBox {
  width: 800px;
  /* display: grid;
  grid-template-columns: repeat(4, 1fr); */
  display: flex;
  gap: 20px;
  background-color: rgb(200, 201, 202);
  padding: 20px;
  overflow: hidden;
}

.card {
  height: 450px;
  background-color: #fff;
  /* width: 100% */
  width: 25%;
  transition: all 1s ease;
}

.card:hover {
  width: 450px;
  /* transition: all 1s ease; */
}

/* .card:hover~ :not(:hover) {
  width: 100%;
  transition: all 1s ease;
} */

.card img {
  width: 100%;
  height: 90%;
}

.card span {
  text-transform: uppercase;
  color: rgb(41, 40, 40);
  font-weight: 600;
  letter-spacing: 1.2px;
  font-size: 20px;
  display: block;
  text-align: center;
  line-height: 30px;
}

<div class="cardBox">
  <div class="card">
    <!-- <img src="/1.jpg" alt=""> -->
    <span>CSS</span>
  </div>
  <div class="card">
    <!-- <img src="/3.jpg" alt=""> -->
    <span>image</span>
  </div>
  <div class="card">
    <!-- <img src="/2.jpg" alt=""> -->
    <span>hover</span>
  </div>
  <div class="card">
    <!-- <img src="/4.jpg" alt=""> -->
    <span>effect</span>
  </div>
</div>
