How to achieve picture stacking effect in css

1. Initial index.html

In order to create the first photo, which is the top one. We just need to add a div containing the img of the photo. That’s all, the rest of the effects are achieved through CSS. Make sure the div's class is stackone. 

<!DOCTYPE html>
<html>
 <head> 
  <meta charset="UTF-8" /> 
  <meta name="viewport" content="width=device-width, initial-scale=1.0" /> 
  <meta http-equiv="X-UA-Compatible" content="ie=edge" /> 
  <title>Photo Stack</title> 
  <style>
    * {
      margin: 0;
      padding: 0;
    }
    html,
    body {
      width: 100%;
      height: 100%;
      overflow: hidden;
    }
    .stackone {
      --img-width: 480px;
      --img-height: 320px;
      border: 6px solid #fff;
      float: left;
      height:var(--img-height);
      width: var(--img-width);
      margin: 50px;
      position: relative;
      -webkit-box-shadow: 2px 2px 5px rgba(0, 0, 0, 0.3);
      -moz-box-shadow: 2px 2px 5px rgba(0, 0, 0, 0.3);
      box-shadow: 2px 2px 5px rgba(0, 0, 0, 0.3);
    }
    .stackone img {
      width: var(--img-width);
    }
  </style> 
 </head> 
 <body> 
  <div> 
   <img  src="../../../assets/image/landscape-4378548_960_720.jpg" / alt="How to achieve picture stacking effect in css" > 
  </div>  
 </body>
</html>

The initial effect is as follows:

2. The First Pseudo Element

Now we add a layer of negative. The effect we want is that the bottom image appears to be underneath the top photo. We can use the CSS pseudo-class: before to achieve this. 

.stackone::before {
  content: "";
  height:var(--img-height);
  width: var(--img-width);
  background: #eff4de;
  border: 6px solid #fff;
  -webkit-box-shadow: 2px 2px 5px rgba(0, 0, 0, 0.3);
  -moz-box-shadow: 2px 2px 5px rgba(0, 0, 0, 0.3);
  box-shadow: 2px 2px 5px rgba(0, 0, 0, 0.3);
}

3. Improve before

Add some positioning to:before, and then set z-index to put it behind. 

.stackone::before {
  content: "";
  height:var(--img-height);
  width: var(--img-width);
  background: #eff4de;
  border: 6px solid #fff;
 
  position: absolute;
  z-index: -1;
  top: 0px;
  left: -10px;
 
  -webkit-box-shadow: 2px 2px 5px rgba(0, 0, 0, 0.3);
  -moz-box-shadow: 2px 2px 5px rgba(0, 0, 0, 0.3);
  box-shadow: 2px 2px 5px rgba(0, 0, 0, 0.3);
 
  -webkit-transform: rotate(-5deg);
  -moz-transform: rotate(-5deg);
  -o-transform: rotate(-5deg);
  -ms-transform: rotate(-5deg);
  transform: rotate(-5deg);
}

4. The Second Pseudo Element

.stackone::after {
  content: "";
  height:var(--img-height);
  width: var(--img-width);
  background: lightblue;
  border: 6px solid #fff;
  position: absolute;
  z-index: -1;
  top: 5px;
  left: 0px;
  -webkit-box-shadow: 2px 2px 5px rgba(0, 0, 0, 0.3);
  -moz-box-shadow: 2px 2px 5px rgba(0, 0, 0, 0.3);
  box-shadow: 2px 2px 5px rgba(0, 0, 0, 0.3);
  -webkit-transform: rotate(4deg);
  -moz-transform: rotate(4deg);
  -o-transform: rotate(4deg);
  -ms-transform: rotate(4deg);
  transform: rotate(4deg);
}
