冲突Hover伪类

Question

在这种情况下，我使用悬停伪类来修改元素，无论是在父类上盘旋，还是当它悬停在上面时。不幸的是，它们有一个相互冲突的属性(都试图定义属性transform)，这就是为什么--我猜想--当按钮悬停但光标改变时，缩放不起作用。是否只使用CSS进行了工作？

​

body {
  overflow: hidden;
 }

#action-panel {
    align-items: center;
    box-sizing: border-box;
    display: flex;
    flex-direction: column;
    justify-content: center;
    padding: 20px 20px 20px 20px;
    position: absolute;
    right: 0;
    transform: translateY(-50%);
    top: 50%;
}

#action-panel:hover .action-button {
    opacity: 1;
    transform: translateX(0);
}

.action-button {
    background-color: lightblue;
    border-radius: 25px;
    height: 50px;
    margin-bottom: 20px;
    opacity: 0;
    transition: opacity 200ms ease-in-out, transform 200ms ease-in-out;
    transform: translateX(calc(100% + 20px));
    width: 50px;
}

.action-button:hover {
    cursor: pointer;
    transform: translateX(0) scale(1.2);
}

.action-button span {
    font-size: 30px;
    left: 50%;
    position: relative;
    transform: translate(-50%, -50%);
    top: 50%;
}

注：

如果您无法从代码中分辨，则需要将光标移动到右侧边缘的中间，以查看我所描述的效果。

通过在下面的样式之前添加#action-panel，提高了它的特异性。在您的代码中，父类型的悬停样式覆盖子元素的悬停样式。

 #action-panel .action-button:hover {
  cursor: pointer;
  transform: translateX(0) scale(1.2);
}

body {
  overflow: hidden;
}

#action-panel {
  align-items: center;
  box-sizing: border-box;
  display: flex;
  flex-direction: column;
  justify-content: center;
  padding: 20px 20px 20px 20px;
  position: absolute;
  right: 0;
  transform: translateY(-50%);
  top: 50%;
}

#action-panel:hover .action-button {
  opacity: 1;
  transform: translateX(0);
}

.action-button {
  background-color: lightblue;
  border-radius: 25px;
  height: 50px;
  margin-bottom: 20px;
  opacity: 0;
  transition: opacity 200ms ease-in-out, transform 200ms ease-in-out;
  transform: translateX(calc(100% + 20px));
  width: 50px;
}

#action-panel .action-button:hover {
  cursor: pointer;
  transform: translateX(0) scale(1.2);
}

.action-button span {
  font-size: 30px;
  left: 50%;
  position: relative;
  transform: translate(-50%, -50%);
  top: 50%;
}
