javascript - 悬停时左侧边距不适用于 Carousel

Question

悬停时，我希望我的图像将其他图像向左和向右移动。目前，悬停时，它会将所有图像仅向右移动。

使用这段代码:

.item-img:hover {
  transform: scale(1.3);
  margin: 0 70px 0 70px;
  opacity: 1;
  z-index: 950;  
}

我本以为我会让两边的图像移动。但是不——还是对的!

因此而不是当前效果(仅右移)

我试图让它双向移动，就像这样

您必须使用 JQuery 来获得您正在寻找的效果，因为当前行为符合 CSS 规则...我所做的是将前一个元素向左推一点，以便它让路让我们的图像缩小...

工作代码段如下:

$(document).ready(function() {
  $("img").mouseenter(function() {
    $(this).prev().css('margin-left', '-10px')
  });
  $("img").mouseleave(function() {
    $(this).prev().css('margin-left', '0px')
  });
});
