css position pseudo elements stacking

Hello I use before & after in my element and it's work well, but the problem that when I set background-color for section the before & after will be disappear I know that this problem appear because of z-index: -1and I know that we can't stacking child element (before & after) above the parent element so what is the solution, I don't need to create any new elements to do this trick:


It's what I need: enter image description here 

section{
    height:400px;
    padding:50px 0;
    background-color:#00fb8f;
}
.box-shadow-1{
    height:200px;
    background-color:#e8e8e8;
    position:relative;
}
.box-shadow-1:before,
.box-shadow-1:after {
  z-index: -1;
  position: absolute;
  content: "";
  bottom: 25px;
  left: 10px;
  width: 50%;
  top: 80%;
  max-width: 300px;
  background-color:#ff0000;
  -moz-box-shadow: 0 20px 20px #777;
  -webkit-box-shadow: 0 20px 20px #777;
  box-shadow: 0 20px 20px #777;
  -webkit-transform: rotate(-8deg);
  -moz-transform: rotate(-8deg);
  -o-transform: rotate(-8deg);
  -ms-transform: rotate(-8deg);
  transform: rotate(-8deg);
}
.box-shadow-1:after {
  -webkit-transform: rotate(8deg);
  -moz-transform: rotate(8deg);
  -o-transform: rotate(8deg);
  -ms-transform: rotate(8deg);
  transform: rotate(8deg);
  right: 10px;
  left: auto;
}
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet"/>
<section>
    <div class="container">
        <div class="row">
            <div class="col-lg-11 col-lg-offset-1">
                <div class="box-shadow-1">
                    Hello World
                </div>
            </div>
        </div>
    </div>

You need to give the box-shadow-1's parent a z-index, like this

.col-lg-11.col-lg-offset-1 {
    position:relative;
    z-index: 0;
}

I also adjusted your pseudo elements a little, so you get the shadow like the posted image

Stack snippet

section{
    height:400px;
    padding:30px 0;
    background-color:#e8e8e8;
}
.col-lg-11.col-lg-offset-1 {        /*  added rule  */
    position:relative;
    z-index: 0;
}
.box-shadow-1{
    height:150px;
    background-color:#00fb8f;
    position:relative;
}
.box-shadow-1:before,
.box-shadow-1:after {
  z-index: -1;
  position: absolute;
  content: "";
  bottom: 25px;
  left: 10px;
  width: 50%;
  height: 20px;
  max-width: 300px;
  background-color:#ff0000;
  -moz-box-shadow: 0 30px 20px #777;
  -webkit-box-shadow: 0 30px 20px #777;
  box-shadow: 0 30px 20px #777;
  -webkit-transform: rotate(-8deg);
  -moz-transform: rotate(-8deg);
  -o-transform: rotate(-8deg);
  -ms-transform: rotate(-8deg);
  transform: rotate(-8deg);
}
.box-shadow-1:after {
  -webkit-transform: rotate(8deg);
  -moz-transform: rotate(8deg);
  -o-transform: rotate(8deg);
  -ms-transform: rotate(8deg);
  transform: rotate(8deg);
  right: 10px;
  left: auto;
}

    <div class="container">
        <div class="row">
            <div class="col-lg-11 col-lg-offset-1">
                <div class="box-shadow-1">
                    Hello World
                </div>
            </div>

Set a z-index value for the parent of box-shadow-1.

section{
    height:400px;
    padding:50px 0;
    background-color:#00fb8f;
}
.box-shadow-1-parent {
  position: relative;
  z-index: 0;
}
.box-shadow-1 {
    height:200px;
    background-color:#e8e8e8;
    position:relative;
}
.box-shadow-1:before,
.box-shadow-1:after {
  z-index: -1;
  position: absolute;
  content: "";
  bottom: 25px;
  left: 10px;
  width: 50%;
  top: 80%;
  max-width: 300px;
  background-color:#ff0000;
  -moz-box-shadow: 0 20px 20px #777;
  -webkit-box-shadow: 0 20px 20px #777;
  box-shadow: 0 20px 20px #777;
  -webkit-transform: rotate(-8deg);
  -moz-transform: rotate(-8deg);
  -o-transform: rotate(-8deg);
  -ms-transform: rotate(-8deg);
  transform: rotate(-8deg);
}
.box-shadow-1:after {
  -webkit-transform: rotate(8deg);
  -moz-transform: rotate(8deg);
  -o-transform: rotate(8deg);
  -ms-transform: rotate(8deg);
  transform: rotate(8deg);
  right: 10px;
  left: auto;

I think the only way to achieve this is to send the <section> to the back and then bring the parent of .box-shadow1 forward like this,

section{
    height:400px;
    padding:50px 0;
    background-color:#00fb8f;
    z-index: -2;
}

.col-lg-11 {
  z-index: 1;
}

As you can see below you achieve what you are looking for.

section{
    height:400px;
    padding:50px 0;
    background-color:#00fb8f;
    z-index: -2;
}

.col-lg-11 {
  z-index: 1;
}

.box-shadow-1{
    height:200px;
    background-color:#e8e8e8;
    position:relative;
}

.box-shadow-1:before,
.box-shadow-1:after {
  z-index: -1;
  position: absolute;
  content: "";
  bottom: 25px;
  left: 10px;
  width: 50%;
  top: 80%;
  max-width: 300px;
  background-color:#ff0000;
  -moz-box-shadow: 0 20px 20px #000;
  -webkit-box-shadow: 0 20px 20px #000;
  box-shadow: 0 20px 20px #777;
  -webkit-transform: rotate(-8deg);
  -moz-transform: rotate(-8deg);
  -o-transform: rotate(-8deg);
  -ms-transform: rotate(-8deg);
  transform: rotate(-8deg);
}

.box-shadow-1:after {
  -webkit-transform: rotate(8deg);
  -moz-transform: rotate(8deg);
  -o-transform: rotate(8deg);
  -ms-transform: rotate(8deg);
  transform: rotate(8deg);
  right: 10px;
  left: auto;
}
