精确定位将2张图像叠加到另一张（背景图像）上

Question

我有3张图片。一个是背景图片，它决定了包围它的div的大小（img {width：100％height：auto），它使我能够动态调整div的大小，同时保持图片的比例锁定。

我还有2张图片，它们的大小等于背景图片的尺寸。它们是透明的，禁止黑色圆形轮廓图像：

我试图将这2张图像放置在背景图像的上方，但我根本无法实现。我需要它们在背景图像上保持固定，以便在调整窗口大小时，它们在调整背景图像的大小时保持其在窗口顶部上方的位置（即与背景图像一起缩小）。这样结束：

有人可以帮我吗？预先感谢您的指导。

Answer 1

将#image-left和#image-right（不是img ）与position:absolute和width:50%（左边，右边一个）

所以基本上添加

#image-left, #image-right{
  position:absolute;
  top:0;
  width:50%;
}
#image-left{left:0;}
#image-right{right:0;}

并删除

#image-left img {
  left: 0;
  top: 0;
}

#image-right img {
  right: 0;
  top:0;
}
