CSS: How to drill all the underlying layers up to the background?

Question:

Tag: css,background-image

Is there any way to create div with a style to drill all the underlying layers up to the background? Wherever such DIV is placed, it should provide an eraser effect. Basically, I'm interested in CSS, but would appreciate if you could suggest any method to reach following result.
Sample is below:

  1. (1) - background
  2. (2) - middle layer's (can be multiple)
  3. (3) - upper div (like eraser, makes all underlying divs transparrent, except background)

enter image description here


Answer:

You can't actually 'drill' a hole but you can overlay your content with a box that eg. has same fixed background as the box in the background using background-attachment: fixed;

.box1, .box3 {
  background: url("http://placekitten.com/g/800/600") repeat fixed center center rgba(0, 0, 0, 0);
}

.box2 {
  background: rgba(255,255,255,0.6);
  min-height: 200px;
  width: 80%;
  margin: 0 auto;
  padding: 2em;
  position: relative;
}

.box3 {
  width: 200px;
  height: 200px;
  border-radius: 50%;
  position: fixed;
  top: 25%;
  left: 25%;
  border: 4px solid red;
  pointer-events: none; /* ignore pointer events */
}
<body class="box1">
  
  <div class="box2">
