很好的时间。我有几个标签与正确的类,我想应用的风格,我想其余的正确的类时,我悬停在至少一个这些div。(记住,我不能改变html文件,只是css文件。)这里看到的图片。

body {
  margin: 0;
}

#container {
  position: relative;
  background-color: #d5d8dc;
  margin-top: 100px;
  margin-left: 100px;
  width: 400px;
  height: 400px;
}

.right {
  background-color: #2ecc71;
  position: absolute;
  width: 320px;
  height: 40px;
}

.right:nth-child(1) {
  left: 20%;
}

.right:nth-child(2) {
  transform: rotate(90deg);
  right: -140px;
  top: 140px;
}

.right:nth-child(3) {
  left: 20%;
  bottom: 20%;
}

.right:nth-child(4) {
  transform: rotate(90deg);
  right: +140px;
  top: 140px;
  z-index: 2;
}

.left {
  background-color: #e74c3c;
  position: absolute;
  width: 320px;
  height: 40px;
}

.left:nth-child(5) {
  left: 0;
  top: 20%;
}

.left:nth-child(6) {
  transform: rotate(90deg);
  right: -60px;
  top: 220px;
}

.left:nth-child(7) {
  left: 0;
  bottom: 0;
}

.left:nth-child(8) {
  transform: rotate(90deg);
  left: -140px;
  top: 220px;
}

.left:hover {
  z-index: 3;
}

.right:hover {
  z-index: 3;
}
<div id="container">
  <div class="right"></div>
  <div class="right"></div>
  <div class="right"></div>
  <div class="right"></div>
  <div class="left"></div>
  <div class="left"></div>
  <div class="left"></div>
  <div class="left"></div>
</div>

您可以在容器上执行此操作,如下所示:

#container:hover .right {
  background-color: yellow;
}

x一个一个一个一个x一个一个二个x

或者,如果您只想悬停在. right div上,那么使用CSS实现这一点的唯一方法是使用:has()等现代选择器,如下所示

#container:has(.right:hover) .right {
  background-color: purple;
}
body {
  margin: 0;
}

#container {
  position: relative;
  background-color: #d5d8dc;
  margin-top: 100px;
  margin-left: 100px;
  width: 400px;
  height: 400px;
}

.right {
  background-color: #2ecc71;
  position: absolute;
  width: 320px;
  height: 40px;
}

.right:nth-child(1) {
  left: 20%;
}

.right:nth-child(2) {
  transform: rotate(90deg);
  right: -140px;
  top: 140px;
}

.right:nth-child(3) {
  left: 20%;
  bottom: 20%;
}

.right:nth-child(4) {
  transform: rotate(90deg);
  right: 140px;
  top: 140px;
  z-index: 2;
}

.left {
  background-color: #e74c3c;
  position: absolute;
  width: 320px;
  height: 40px;
}

.left:nth-child(5) {
  left: 0;
  top: 20%;
}

.left:nth-child(6) {
  transform: rotate(90deg);
  right: -60px;
  top: 220px;
}

.left:nth-child(7) {
  left: 0;
  bottom: 0;
}

.left:nth-child(8) {
  transform: rotate(90deg);
  left: -140px;
  top: 220px;
}

#container:has(.right:hover) .right {
  background-color: purple;
}
<div id="container">
  <div class="right"></div>
  <div class="right"></div>
  <div class="right"></div>
  <div class="right"></div>
  <div class="left"></div>
  <div class="left"></div>
  <div class="left"></div>
  <div class="left"></div>
</div>

但是:has()选择器还没有登陆Firefox,希望很快就能登陆。

除了Glenn Flannagananswer之外,如果你想让绿色方块(.right)只在悬停时出现在前面(而不是在容器悬停时),你不需要使用has,你可以使用~兄弟选择器修改leftz-index

body {
  margin: 0;
}

#container {
  position: relative;
  background-color: #d5d8dc;
  margin-top: 100px;
  margin-left: 100px;
  width: 400px;
  height: 400px;
}

.right {
  background-color: #2ecc71;
  position: absolute;
  width: 320px;
  height: 40px;
  z-index: 1;
}

.right:nth-child(1) {
  left: 20%;
}

.right:nth-child(2) {
  transform: rotate(90deg);
  right: -140px;
  top: 140px;
}

.right:nth-child(3) {
  left: 20%;
  bottom: 20%;
}

.right:nth-child(4) {
  transform: rotate(90deg);
  right: +140px;
  top: 140px;
  z-index: 3;
}

.left {
  background-color: #e74c3c;
  position: absolute;
  width: 320px;
  height: 40px;
  z-index: 2;
}

.left:nth-child(5) {
  left: 0;
  top: 20%;
}

.left:nth-child(6) {
  transform: rotate(90deg);
  right: -60px;
  top: 220px;
}

.left:nth-child(7) {
  left: 0;
  bottom: 0;
}

.left:nth-child(8) {
  transform: rotate(90deg);
  left: -140px;
  top: 220px;
}

.right:hover~.left {
  z-index: 0;
}
<div id="container">
  <div class="right"></div>
  <div class="right"></div>
  <div class="right"></div>
  <div class="right"></div>
  <div class="left"></div>
  <div class="left"></div>
  <div class="left"></div>
  <div class="left"></div>
</div>

请注意,如果您想更改.right样式,在某些情况下,您需要选择以前的元素(不太受支持)
