CSS page up box-shadow effect

We can style a lot with CSS, but the main thing is the imagination, the more you can imagine the more uniquely you can represent things. Web designing is becoming a trend nowadays and one of the most competitive field as well. Keeping this in mind I am going to discuss how we can use the box-shadow effect to make a beautiful page up effect and hence contributing a bit to your competition.


HTML markup used

The following HTML code is used to show the above page up effect.
<body>
  <div id="box">
    CSS Box shadow
  </div>
</body>


The necessary CSS

Following is the CSS code required to apply the page up effect to an HTML element, in this tutorial we are applying the page up box-shadow effect to the HTML div element with ID #box.
#box {
  width: 600px;
  height: 250px;
  background-color: #F5DA81;
  position: relative;
  left: 400px;
  top: 50px;
  text-align: center;
  line-height: 250px;
  font-size: 35px;
  border: 1px solid #EECF67;
  color: #222222;
  font-family: Segoe UI;
}

/*********THE SHADOW ON THE LEFT*********/
#box:before {
  content: "";
  width: 200px;
  height: 50px;
  position: absolute;
  top: 186px;
  left:30px;
   -moz-box-shadow: 0px 0px 20px 20px #BDBDBD;
  -webkit-box-shadow: 0px 0px 20px 20px #BDBDBD;
  box-shadow: 0px 0px 20px 20px #BDBDBD;
  -webkit-transform: rotate(-5deg);
  -moz-transform: rotate(-5deg);
  -ms-transform: rotate(-5deg);
  -o-transform: rotate(-5deg);
  z-index: -1;
}

/*********THE SHADOW ON THE RIGHT*********/
#box:after {
  content: "";
  width: 200px;
  height: 50px;
  position: absolute;
  top: 186px;
  right:30px;
   -moz-box-shadow: 0px 0px 20px 20px #BDBDBD;
  -webkit-box-shadow: 0px 0px 20px 20px #BDBDBD;
  box-shadow: 0px 0px 20px 20px #BDBDBD;
  -webkit-transform: rotate(5deg);
  -moz-transform: rotate(5deg);
  -ms-transform: rotate(5deg);
  -o-transform: rotate(5deg);
  z-index: -1;
}
To use this effect you might need to change the positioning of after: and before: pseudo elements, also don't forget to replace the id #box with your HTML element's ID or class.
